Google has said for years that selling links that pass PageRank violates our quality guidelines. We continue to reiterate that guidance periodically to help remind site owners and webmasters of that policy.

Please be wary if someone approaches you and wants to pay you for links or "advertorial" pages on your site that pass PageRank. Selling links (or entire advertorial pages with embedded links) that pass PageRank violates our quality guidelines, and Google does take action on such violations. The consequences for a linkselling site start with losing trust in Google's search results, as well as reduction of the site's visible PageRank in the Google Toolbar. The consequences can also include lower rankings for that site in Google's search results.

If you receive a warning for selling links that pass PageRank in Google's Webmaster Tools, you'll see a notification message to look for "possibly artificial or unnatural links on your site pointing to other sites that could be intended to manipulate PageRank." That's an indication that your site has lost trust in Google's index.

To address the issue, make sure that any paid links on your site don't pass PageRank. You can remove any paid links or advertorial pages, or make sure that any paid hyperlinks have the rel="nofollow" attribute. After ensuring that no paid links on your site pass PageRank, you can submit a reconsideration request and if you had a manual webspam action on your site, someone at Google will review the request. After the request has been reviewed, you'll get a notification back about whether the reconsideration request was granted or not.

We do take this issue very seriously, so we recommend you avoid selling (and buying) links that pass PageRank in order to prevent loss of trust, lower PageRank in the Google Toolbar, lower rankings, or in an extreme case, removal from Google's search results.

Today we’re happy to announce an updated version of our Webmaster Quality Guidelines. Both our basic quality guidelines and many of our more specific articles (like those on links schemes or hidden text) have been reorganized and expanded to provide you with more information about how to create quality websites for both users and Google.

The main message of our quality guidelines hasn’t changed: Focus on the user. However, we’ve added more guidance and examples of behavior that you should avoid in order to keep your site in good standing with Google’s search results. We’ve also added a set of quality and technical guidelines for rich snippets, as structured markup is becoming increasingly popular.

We hope these updated guidelines will give you a better understanding of how to create and maintain Google-friendly websites.

We’ve gotten several questions recently about whether website testing—such as A/B or multivariate testing—affects a site’s performance in search results. We’re glad you’re asking, because we’re glad you’re testing! A/B and multivariate testing are great ways of making sure that what you’re offering really appeals to your users.

Before we dig into the implications for search, a brief primer:
Website testing is when you try out different versions of your website (or a part of your website), and collect data about how users react to each version. You use software to track which version causes users to do-what-you-want-them-to-do most often: which one results in the most purchases, or the most email signups, or whatever you’re testing for. After the test is finished you can update your website to use the “winner” of the test—the most effective content.

A/B testing is when you run a test by creating multiple versions of a page, each with its own URL. When users try to access the original URL, you redirect some of them to each of the variation URLs and then compare users’ behaviour to see which page is most effective.

Multivariate testing is when you use software to change differents parts of your website on the fly. You can test changes to multiple parts of a page—say, the heading, a photo, and the ‘Add to Cart’ button—and the software will show variations of each of these sections to users in different combinations and then statistically analyze which variations are the most effective. Only one URL is involved; the variations are inserted dynamically on the page.

So how does this affect what Googlebot sees on your site? Will serving different content variants change how your site ranks? Below are some guidelines for running an effective test with minimal impact on your site’s search performance.

• No cloaking.
  Cloaking—showing one set of content to humans, and a different set to Googlebot—is against our Webmaster Guidelines, whether you’re running a test or not. Make sure that you’re not deciding whether to serve the test, or which content variant to serve, based on user-agent. An example of this would be always serving the original content when you see the user-agent “Googlebot.” Remember that infringing our Guidelines can get your site demoted or removed from Google search results—probably not the desired outcome of your test.
• Use rel=“canonical”.
  If you’re running an A/B test with multiple URLs, you can use the rel=“canonical” link attribute on all of your alternate URLs to indicate that the original URL is the preferred version. We recommend using rel=“canonical” rather than a noindex meta tag because it more closely matches your intent in this situation. Let’s say you were testing variations of your homepage; you don’t want search engines to not index your homepage, you just want them to understand that all the test URLs are close duplicates or variations on the original URL and should be grouped as such, with the original URL as the canonical. Using noindex rather than rel=“canonical” in such a situation can sometimes have unexpected effects (e.g., if for some reason we choose one of the variant URLs as the canonical, the “original” URL might also get dropped from the index since it would get treated as a duplicate).
• Use 302s, not 301s.
  If you’re running an A/B test that redirects users from the original URL to a variation URL, use a 302 (temporary) redirect, not a 301 (permanent) redirect. This tells search engines that this redirect is temporary—it will only be in place as long as you’re running the experiment—and that they should keep the original URL in their index rather than replacing it with the target of the redirect (the test page). JavaScript-based redirects are also fine.
• Only run the experiment as long as necessary.
  The amount of time required for a reliable test will vary depending on factors like your conversion rates, and how much traffic your website gets; a good testing tool should tell you when you’ve gathered enough data to draw a reliable conclusion. Once you’ve concluded the test, you should update your site with the desired content variation(s) and remove all elements of the test as soon as possible, such as alternate URLs or testing scripts and markup. If we discover a site running an experiment for an unnecessarily long time, we may interpret this as an attempt to deceive search engines and take action accordingly. This is especially true if you’re serving one content variant to a large percentage of your users.

The recommendations above should result in your tests having little or no impact on your site in search results. However, depending on what types of content you’re testing, it may not even matter much if Googlebot crawls or indexes some of your content variations while you’re testing. Small changes, such as the size, color, or placement of a button or image, or the text of your “call to action” (“Add to cart” vs. “Buy now!”), can have a surprising impact on users’ interactions with your webpage, but will often have little or no impact on that page’s search result snippet or ranking. In addition, if we crawl your site often enough to detect and index your experiment, we’ll probably index the eventual updates you make to your site fairly quickly after you’ve concluded the experiment.

To learn more about website testing, check out these articles on Content Experiments, our free testing tool in Google Analytics. You can also ask questions about website testing in the Analytics Help Forum, or about search impact in the Webmaster Help Forum.

We’ve made a lot of progress on making the entire reconsideration request process more transparent. We aren’t able to reply to individual requests with specific feedback, but now many webmasters will be able to find out if their site has been affected by a manual action and they’ll know the outcome of the reconsideration review. In an ideal world, Google could be completely transparent about how every part of our rankings work. However, we have to maintain a delicate balance: trying to give as much information to webmasters as we can without letting spammers probe how to do more harm to users. We're happy that Google has set the standard on tools, transparency, and communication with site owners, but we'll keep looking for ways to do even better.

A popular question on our Webmaster Help Forum is in regard to best practices for organic link building. There seems to be some confusion, especially among less experienced webmasters, on how to approach the topic. Different perspectives have been shared, and we would also like to explain our viewpoint on earning quality links.

If your site is rather new and still unknown, a good way marketing technique is to get involved in the community around your topic. Interact and contribute on forums and blogs. Just keep in mind to contribute in a positive way, rather than spamming or soliciting for your site. Just building a reputation can drive people to your site. And they will keep on visiting it and linking to it. If you offer long-lasting, unique and compelling content -- something that lets your expertise shine -- people will want to recommend it to others. Great content can serve this purpose as much as providing useful tools.

A promising way to create value for your target group and earn great links is to think of issues or problems your users might encounter. Visitors are likely to appreciate your site and link to it if you publish a short tutorial or a video providing a solution, or a practical tool. Survey or original research results can serve the same purpose, if they turn out to be useful for the target audience. Both methods grow your credibility in the community and increase visibility. This can help you gain lasting, merit-based links and loyal followers who generate direct traffic and "spread the word." Offering a number of solutions for different problems could evolve into a blog which can continuously affect the site's reputation in a positive way.

Humor can be another way to gain both great links and get people to talk about your site. With Google Buzz and other social media services constantly growing, entertaining content is being shared now more than ever. We've seen all kinds of amusing content, from ASCII art embedded in a site's source code to funny downtime messages used as a viral marketing technique to increase the visibility of a site. However, we do not recommend counting only on short-lived link-bait tactics. Their appeal wears off quickly and as powerful as marketing stunts can be, you shouldn't rely on them as a long-term strategy or as your only marketing effort.

It's important to clarify that any legitimate link building strategy is a long-term effort. There are those who advocate for short-lived, often spammy methods, but these are not advisable if you care for your site's reputation. Buying PageRank-passing links or randomly exchanging links are the worst ways of attempting to gather links and they're likely to have no positive impact on your site's performance over time. If your site's visibility in the Google index is important to you it's best to avoid them.

Directory entries are often mentioned as another way to promote young sites in the Google index. There are great, topical directories that add value to the Internet. But there are not many of them in proportion to those of lower quality. If you decide to submit your site to a directory, make sure it's on topic, moderated, and well structured. Mass submissions, which are sometimes offered as a quick work-around SEO method, are mostly useless and not likely to serve your purposes.

It can be a good idea to take a look at similar sites in other markets and identify the elements of those sites that might work well for yours, too. However, it's important not to just copy success stories but to adapt them, so that they provide unique value for your visitors.



Finally, consider making linking to your site easier for less tech savvy users. Similar to the way we do it on YouTube, offering bookmarking services for social sites like Twitter or Facebook can help spread the word about the great content on your site and draw users' attention.

As usual, we'd like to hear your opinion. You're welcome to comment here in the blog, or join our Webmaster Help Forum community.

Webmaster level: Intermediate/Advanced

Webmasters who check their incoming links in Webmaster Tools often ask us what they can do when they see low-quality links. Understandably, many site owners are trying to build a good reputation for their sites, and some believe that having poor-quality incoming links can be perceived as "being part of a bad neighbourhood," which over time might harm their site's ranking.


If your site receives links that look similarly dodgy, don't be alarmed... read on!

While it's true that linking is a significant factor in Google's ranking algorithms, it's just one of many. I know we say it a lot, but having something that people want to look at or use—unique, engaging content, or useful tools and services—is also a huge factor. Other factors can include how a site is structured, whether the words of a user's query appear in the title, how close the words are on the page, and so on. The point is, if you happen to see some low quality sites linking to you, it's important to keep in mind that linking is just one aspect among many of how Google judges your site. If you have a well-structured and regularly maintained site with original, high-quality content, those are the sorts of things that users will see and appreciate.

That having said, in an ideal world you could have your cake and eat it too (or rather, you could have a high-quality site and high-quality backlinks). You may also be concerned about users' perception of your site if they come across it via a batch of spammy links. If the number of poor-quality links is manageable, and/or if it looks easy to opt-out or get those links removed from the site that's linking to you, it may be worth it to try to contact the site(s) and ask them to remove their links. Remember that this isn't something that Google can do for you; we index content that we find online, but we don't control that content or who's linking to you.

If you run into some uncooperative site owners, however, don't fret for too long. Instead, focus on things that are under your control. Generally, you as a webmaster don't have much control over things like who links to your site. You do, however, have control over many other factors that influence indexing and ranking. Organize your content; do a mini-usability study with family or friends. Ask for a site review in your favorite webmaster forums. Use a website testing tool to figure out what gets you the most readers, or the biggest sales. Take inspiration from your favorite sites, or your competitors—what do they do well? What makes you want to keep coming back to their sites, or share them with your friends? What can you learn from them? Time spent on any of these activities is likely to have a larger impact on your site's overall performance than time spent trying to hunt down and remove every last questionable backlink.

Finally, keep in mind that low-quality links rarely stand the test of time, and may disappear from our link graph relatively quickly. They may even already be being discounted by our algorithms. If you want to make sure Google knows about these links and is valuing them appropriately, feel free to bring them to our attention using either our spam report or our paid links report.

About a year ago, in response to user feedback, we created a paid links reporting form within Webmaster Tools. User feedback, through reporting paid links, webspam, or suggestions in our Webmaster Help Group, has been invaluable in ensuring that the quality of our index and our tools is as high as possible. Today, I'd like to highlight the impact that reporting paid links and webspam has had on our index. In a future post, I'll showcase how user feedback and concerns in the Webmaster Help Group have helped us improve our Help Center documentation and Webmaster Tools.

Reporting Paid Links

As mentioned in the post Information about buying and selling links that pass PageRank, Google reserves the right to take action on sites that buy or sell links that pass PageRank for the purpose of manipulating search engine rankings. Even though we work hard to discount these links through algorithmic detection, if you see a site that is buying or selling links that pass PageRank, please let us know. Over the last year, users have submitted thousands and thousands of paid link reports to Google, and each report can contain multiple websites that are suspected of selling links. These reports are actively reviewed, and the feedback is invaluable to improve our search algorithms. We also are willing to take manual action on a significant fraction of paid link reports as we continue to improve our algorithms. More importantly, the hard work of users who have already reported paid links has helped improve the quality of our index for millions. For more information on reporting paid links, check out this Help Center article.

Reporting Webspam

Google has also provided a form to report general webspam since November 2001. We appreciate users who alert us to potential abuses for the sake of the whole Internet community. Spam reports come in two flavors: an authenticated form that requires registration in Webmaster Tools, and an unauthenticated form. We receive hundreds of reports each day. Spam reports to the authenticated form are given more weight and are individually investigated more often. Spam reports to the unauthenticated form are assessed in terms of impact, and a large fraction of those are reviewed as well. As Udi Manber, VP of Engineering & Search Quality mentioned in his recent blog post on our Official Google Blog, in 2007 more than 450 new improvements were made to our search algorithms. A number of those improvements were related to webspam. It's not an understatement to say that users who have taken the time to report spam were essential to many of those algorithmic enhancements.

Going forward

As users' expectations of search increase daily, we know it's important to provide a high quality index with relevant results. We're always happy to hear stories in our Webmaster Help Group from users who have have reported spam with noticeable results in our Webmaster Help Group. Now that you know how Google uses feedback to improve our search quality, you may want to tell us about webspam you've seen in our results. Please use our authenticated form to report paid links or other types of webspam. Thanks again for taking the time to help us improve.

Many of you have asked for more information regarding webserving techniques (especially related to Googlebot), so we made a short glossary of some of the more unusual methods.

• Geolocation: Serving targeted/different content to users based on their location. As a webmaster, you may be able to determine a user's location from preferences you've stored in their cookie, information pertaining to their login, or their IP address. For example, if your site is about baseball, you may use geolocation techniques to highlight the Yankees to your users in New York.
  
  The key is to treat Googlebot as you would a typical user from a similar location, IP range, etc. (i.e. don't treat Googlebot as if it came from its own separate country—that's cloaking).


• IP delivery: Serving targeted/different content to users based on their IP address, often because the IP address provides geographic information. Because IP delivery can be viewed as a specific type of geolocation, similar rules apply. Googlebot should see the same content a typical user from the same IP address would see.
  
  (Author's warning: This 7.5-minute video may cause drowsiness. Even if you're really interested in IP delivery or multi-language sites, it's a bit uneventful.)


• Cloaking: Serving different content to users than to Googlebot. This is a violation of our webmaster guidelines. If the file that Googlebot sees is not identical to the file that a typical user sees, then you're in a high-risk category. A program such as md5sum or diff can compute a hash to verify that two different files are identical.


• First click free: Implementing Google News' First click free policy for your content allows you to include your premium or subscription-based content in Google's websearch index without violating our quality guidelines. You allow all users who find your page using Google search to see the full text of the document, even if they have not registered or subscribed. The user's first click to your content area is free. However, you can block the user with a login or payment request when he clicks away from that page to another section of your site.
  
  If you're using First click free, the page displayed to users who visit from Google must be identical to the content that is shown to the Googlebot.

Still have questions?  We'll see you at the related thread in our Webmaster Help Group.

Our goal is to provide users the best search experience by presenting equitable and accurate results. We enjoy working with webmasters, and an added benefit of our working together is that when you make better and more accessible content, the internet, as well as our index, improves. This in turn allows us to deliver more relevant search results to users.

If, however, a webmaster chooses to buy or sell links for the purpose of manipulating search engine rankings, we reserve the right to protect the quality of our index. Buying or selling links that pass PageRank violates our webmaster guidelines. Such links can hurt relevance by causing:

- Inaccuracies: False popularity and links that are not fundamentally based on merit, relevance, or authority
- Inequities: Unfair advantage in our organic search results to websites with the biggest pocketbooks

In order to stay within Google's quality guidelines, paid links should be disclosed through a rel="nofollow" or other techniques such as doing a redirect through a page which is robots.txt'ed out. Here's more information explaining our stance on buying and selling links that pass PageRank:

February 2003: Google's official quality guidelines have advised "Don't participate in link schemes designed to increase your site's ranking or PageRank" for several years.

September 2005: I posted on my blog about text links and PageRank.

December 2005: Another post on my blog discussed this issue, and said

Many people who work on ranking at search engines think that selling links can lower the quality of links on the web. If you want to buy or sell a link purely for visitors or traffic and not for search engines, a simple method exists to do so (the nofollow attribute). Google’s stance on selling links is pretty clear and we’re pretty accurate at spotting them, both algorithmically and manually. Sites that sell links can lose their trust in search engines.

September 2006: In an interview with John Battelle, I noted that "Google does consider it a violation of our quality guidelines to sell links that affect search engines."

January 2007: I posted on my blog to remind people that "links in those paid-for posts should be made in a way that doesn’t affect search engines."

April 2007: We provided a mechanism for people to report paid links to Google.

June 2007: I addressed paid links in my keynote discussion during the Search Marketing Expo (SMX) conference in Seattle. Here's a video excerpt from the keynote discussion. It's less than a minute long, but highlights that Google is willing to use both algorithmic and manual detection of paid links that violate our quality guidelines, and that we are willing to take stronger action on such links in the future.

June 2007: A post on the official Google Webmaster Blog noted that "Buying or selling links to manipulate results and deceive search engines violates our guidelines." The post also introduced a new official form in Google's webmaster console so that people could report buying or selling of links.

June 2007: Google added more specific guidance to our official webmaster documentation about how to report buying or selling links and what sort of link schemes violate our quality guidelines.

August 2007: I described Google's official position on buying and selling links in a panel dedicated to paid links at the Search Engine Strategies (SES) conference in San Jose.

September 2007: In a post on my blog recapping the SES San Jose conference, I also made my presentation available to the general public (PowerPoint link).

October 2007: Google provided comments for a Forbes article titled "Google Purges the Payola".

October 2007: Google officially confirmed to Search Engine Land that we were taking stronger action on this issue, including decreasing the toolbar PageRank of sites selling links that pass PageRank.

October 2007: An email that I sent to Search Engine Journal also made it clear that Google was taking stronger action on buying/selling links that pass PageRank.

We appreciate the feedback that we've received on this issue. A few of the more prevalent questions:

Q: Is buying or selling links that pass PageRank a violation of Google's guidelines? Why?
A: Yes, it is, for the reasons we mentioned above. I also recently did a post on my personal blog that walks through an example of why search engines wouldn't want to count such links. On a serious medical subject (brain tumors), we highlighted people being paid to write about a brain tumor treatment when they hadn't been aware of the treatment before, and we saw several cases where people didn't do basic research (or even spellchecking!) before writing paid posts.

Q: Is this a Google-only issue?
A: No. All the major search engines have opposed buying and selling links that affect search engines. For the Forbes article Google Purges The Payola, Andy Greenberg asked other search engines about their policies, and the results were unanimous. From the story:

Search engines hate this kind of paid-for popularity. Google's Webmaster guidelines ban buying links just to pump search rankings. Other search engines including Ask, MSN, and Yahoo!, which mimic Google's link-based search rankings, also discourage buying and selling links.

Other engines have also commented about this individually, e.g. a search engine representative from Microsoft commented in a recent interview and said

The reality is that most paid links are a.) obviously not objective and b.) very often irrelevant. If you are asking about those then the answer is absolutely there is a risk. We will not tolerate bogus links that add little value to the user experience and are effectively trying to game the system.

Q: Is that why we've seen some sites that sell links receive lower PageRank in the Google toolbar?
A: Yes. If a site is selling links, that can affect our opinion about the value of that site or cause us to lose trust in that site.

Q: What recourse does a site owner have if their site was selling links that pass PageRank, and the site's PageRank in the Google toolbar was lowered?
A: The site owner can address the violations of the webmaster guidelines and submit a reconsideration request in Google's Webmaster Central console. Before doing a reconsideration request, please make sure that all sold links either do not pass PageRank or are removed.

Q: Is Google trying to tell webmasters how to run their own site?
A: No. We're giving advice to webmasters who want to do well in Google. As I said in this video from my keynote discussion in June 2007, webmasters are welcome to make their sites however they like, but Google in turn reserves the right to protect the quality and relevance of our index. To the best of our knowledge, all the major search engines have adopted similar positions.

Q: Is Google trying to crack down on other forms of advertisements used to drive traffic?
A: No, not at all. Our webmaster guidelines clearly state that you can use links as means to get targeted traffic. In fact, in the presentation I did in August 2007, I specifically called out several examples of non-Google advertising that are completely within our guidelines. We just want disclosure to search engines of paid links so that the paid links won't affect search engines.

Q: I'm aware of a site that appears to be buying/selling links. How can I get that information to Google?
A: Read our official blog post about how to report paid links from earlier in 2007. We've received thousands and thousands of reports in just a few months, but we welcome more reports. We appreciate the feedback, because it helps us take direct action as well as improve our existing algorithmic detection. We also use that data to train new algorithms for paid links that violate our quality guidelines.

Q: Can I get more information?
A: Sure. I wrote more answers about paid links earlier this year if you'd like to read them. And if you still have questions, you can join the discussion in our Webmaster Help Group.

First, a brief recap: In late 2005, we started emailing webmasters to let them know that their site is violating our Webmaster Guidelines and that we have temporarily removed some of their pages from our index. A few months ago we put these emails on hold due to a number of spoofed messages being sent from outside Google, primarily to German webmasters. Then, in mid-July, we launched Message Center in our webmaster console, which allows us to send messages to verified site owners.

While Message Center is great for verified site owners, it doesn't allow us to notify webmasters who aren't registered in Google's Webmaster Tools. For this reason, we plan to resume sending emails in addition to the Message Center notifications. Please note that, as before, our emails will not include attachments. Currently, the Message Center won't keep messages waiting if you haven't previously registered, but we hope to add that feature in the next few months. We'll keep you posted as things change.

Written by Maile Ohye
Today we're launching our Message Center, a new way for webmasters to receive personalized information from Google in our webmaster console. Should we need to contact you, you'll see a notification in your Webmaster Tools dashboard.


Initially the messages will refer to search quality issues, but over time we'll use the Message Center as a communication channel for more types of information. Here's an example: informing the site owner about hidden text, a violation in our webmaster guidelines.


For our webmasters outside the U.S., we’re also pleased to tell you that Message Center is capable of providing information in all supported Webmaster Tools languages (French, Italian, German, Spanish, Danish, Dutch, Swedish, Russian, Chinese-Simplified, Chinese-Traditional, Korean, Japanese, etc.), across all countries.

Right now the number of sites we’re contacting is small, but we hope to expand this program over time. We’re also really happy that the Message Center lets us communicate with webmasters in an authenticated way. As time goes on, we’ll keep looking for even more ways to improve communication with site owners, but right now, why not claim your site in our webmaster tools so that we can give you a heads-up of any issues that we see?

At Google, we are always working hard to provide searchers with the best possible results. We've found that our spam reporting form is a great way to get your input as we continue to improve our results. Some of you have asked for a way to report paid links as well.

Links are an important signal in our PageRank calculations, as they tend to indicate when someone has found a page useful. Links that are purchased are great for advertising and traffic purposes, but aren't useful for PageRank calculations. Buying or selling links to manipulate results and deceive search engines violates our guidelines.

Today, in response to your request, we're providing a paid links reporting form within Webmaster Tools. To use the form, simply log in and provide information on the sites buying and selling links for purposes of search engine manipulation. We'll review each report we get and use this feedback to improve our algorithms and improve our search results. in some cases we may also take individual action on sites.

If you are selling links for advertising purposes, there are many ways you can designate this, including:

• Adding a rel="nofollow" attribute to the href tag
• Redirecting the links to an intermediate page that is blocked from search engines with a robots.txt file

We value your input and look forward to continuing to improve our great partnership with you.

At SMX Advanced on Monday, Matt Cutts talked about our webmaster guidelines. Later, during Q&A, someone asked about adding more detail to the guidelines: more explanation about violations and more actionable help on how to improve sites. You ask -- we deliver! On Tuesday, Matt told the SMX crowd that we'd updated the guidelines overnight to include exactly those things! We work fast around here. (OK, maybe we had been working on some of it already.)

So, what's new? Well, the guidelines themselves haven't changed. But the specific quality guidelines now link to expanded information to help you better understand how to spot and fix any issues. That section is below so you can click through to explore these new details.

Quality guidelines - specific guidelines

• Avoid hidden text or hidden links.
• Don't use cloaking or sneaky redirects.
• Don't send automated queries to Google.
• Don't load pages with irrelevant keywords.
• Don't create multiple pages, subdomains, or domains with substantially duplicate content.
• Don't create pages that install viruses, trojans, or other badware.
• Avoid "doorway" pages created just for search engines, or other "cookie cutter" approaches such as affiliate programs with little or no original content.
• If your site participates in an affiliate program, make sure that your site adds value. Provide unique and relevant content that gives users a reason to visit your site first.

As Riona MacNarmara recently posted in our discussion forum, we are working to expand our webmaster help content even further and want your input. If you have suggestions, please post them in either the thread or as a comment to this post. We would love to hear from you!
