Google and Duplicate Content Guidelines

Duplicate content generally refers to substantive blocks of content within or across domains that either completely match other content or are appreciably similar. Mostly, this is not deceptive in origin. Examples of non-malicious duplicate content could include:

Discussion forums that can generate both regular and stripped-down pages targeted at mobile devices
Store items shown or linked via multiple distinct URLs
Printer-only versions of web pages
If your site contains multiple pages with largely identical content, there are a number of ways you can indicate your preferred URL to Google. (This is called “canonicalization”.) More information about canonicalization.

However, in some cases, content is deliberately duplicated across domains in an attempt to manipulate search engine rankings or win more traffic. Deceptive practices like this can result in a poor user experience, when a visitor sees substantially the same content repeated within a set of search results.

Google tries hard to index and show pages with distinct information. This filtering means, for instance, that if your site has a “regular” and “printer” version of each article, and neither of these is blocked with a noindex meta tag, we’ll choose one of them to list. In the rare cases in which Google perceives that duplicate content may be shown with intent to manipulate our rankings and deceive our users, we’ll also make appropriate adjustments in the indexing and ranking of the sites involved. As a result, the ranking of the site may suffer, or the site might be removed entirely from the Google index, in which case it will no longer appear in search results.

There are some steps you can take to proactively address duplicate content issues, and ensure that visitors see the content you want them to.

Use 301s: If you’ve restructured your site, use 301 redirects (“RedirectPermanent”) in your .htaccess file to smartly redirect users, Googlebot, and other spiders. (In Apache, you can do this with an .htaccess file; in IIS, you can do this through the administrative console.)

Be consistent: Try to keep your internal linking consistent. For example, don’t link to and and

Use top-level domains: To help us serve the most appropriate version of a document, use top-level domains whenever possible to handle country-specific content. We’re more likely to know that contains Germany-focused content, for instance, than or

Syndicate carefully: If you syndicate your content on other sites, Google will always show the version we think is most appropriate for users in each given search, which may or may not be the version you’d prefer. However, it is helpful to ensure that each site on which your content is syndicated includes a link back to your original article. You can also ask those who use your syndicated material to use the noindex meta tag to prevent search engines from indexing their version of the content.

Use Webmaster Tools to tell us how you prefer your site to be indexed: You can tell Google your preferred domain (for example, or

Minimize boilerplate repetition: For instance, instead of including lengthy copyright text on the bottom of every page, include a very brief summary and then link to a page with more details. In addition, you can use the Parameter Handling tool to specify how you would like Google to treat URL parameters.

Avoid publishing stubs: Users don’t like seeing “empty” pages, so avoid placeholders where possible. For example, don’t publish pages for which you don’t yet have real content. If you do create placeholder pages, use the noindex meta tag to block these pages from being indexed.

Understand your content management system: Make sure you’re familiar with how content is displayed on your web site. Blogs, forums, and related systems often show the same content in multiple formats. For example, a blog entry may appear on the home page of a blog, in an archive page, and in a page of other entries with the same label.

Minimize similar content: If you have many pages that are similar, consider expanding each page or consolidating the pages into one. For instance, if you have a travel site with separate pages for two cities, but the same information on both pages, you could either merge the pages into one page about both cities or you could expand each page to contain unique content about each city.

Google no longer recommends blocking crawler access to duplicate content on your website, whether with a robots.txt file or other methods. If search engines can’t crawl pages with duplicate content, they can’t automatically detect that these URLs point to the same content and will therefore effectively have to treat them as separate, unique pages. A better solution is to allow search engines to crawl these URLs, but mark them as duplicates by using the rel=”canonical” link element, the URL parameter handling tool, or 301 redirects. In cases where duplicate content leads to us crawling too much of your website, you can also adjust the crawl rate setting in Webmaster Tools.

Duplicate content on a site is not grounds for action on that site unless it appears that the intent of the duplicate content is to be deceptive and manipulate search engine results. If your site suffers from duplicate content issues, and you don’t follow the advice listed above, we do a good job of choosing a version of the content to show in our search results.

However, if our review indicated that you engaged in deceptive practices and your site has been removed from our search results, review your site carefully. If your site has been removed from our search results, review our webmaster guidelines for more information. Once you’ve made your changes and are confident that your site no longer violates our guidelines, submit your site for reconsideration.

If you find that another site is duplicating your content by scraping (misappropriating and republishing) it, it’s unlikely that this will negatively impact your site’s ranking in Google search results pages. If you do spot a case that’s particularly frustrating, you are welcome to file a DMCA request to claim ownership of the content and request removal of the other site from Google’s index.

How To Create Good Meta Descriptions?

How to create good meta descriptions? Why? Google has just released the detail guide about this topic. We would like to share this useful information with our site visitors. We do hope it will help webmasters to have a more friendly site with Google to dirve more website traffics, more business.

The HTML suggestions page in Webmaster Tools lists pages where Google has detected missing or problematic meta descriptions. (To see this page, click Diagnostics in the left-hand menu of the site Dashboard. Then click HTML suggestions.)
Differentiate the descriptions for different pages. Using identical or similar descriptions on every page of a site isn’t very helpful when individual pages appear in the web results. In these cases we’re less likely to display the boilerplate text. Wherever possible, create descriptions that accurately describe the specific page. Use site-level descriptions on the main home page or other aggregation pages, and use page-level descriptions everywhere else. If you don’t have time to create a description for every single page, try to prioritize your content: At the very least, create a description for the critical URLs like your home page and popular pages.
Include clearly tagged facts in the description. The meta description doesn’t just have to be in sentence format; it’s also a great place to include structured data about the page. For example, news or blog postings can list the author, date of publication, or byline information. This can give potential visitors very relevant information that might not be displayed in the snippet otherwise. Similarly, product pages might have the key bits of information – price, age, manufacturer – scattered throughout a page. A good meta description can bring all this data together. For example, the following meta description provides detailed information about a book.

In this example, information is clearly tagged and separated.

Programmatically generate descriptions. For some sites, like news media sources, generating an accurate and unique description for each page is easy: since each article is hand-written, it takes minimal effort to also add a one-sentence description. For larger database-driven sites, like product aggregators, hand-written descriptions can be impossible. In the latter case, however, programmatic generation of the descriptions can be appropriate and are encouraged. Good descriptions are human-readable and diverse, as we talked about in the first point above. The page-specific data we mentioned in the second point is a good candidate for programmatic generation. Keep in mind that meta descriptions comprised of long strings of keywords don’t give users a clear idea of the page’s content, and are less likely to be displayed in place of a regular snippet.
Use quality descriptions. Finally, make sure your descriptions are truly descriptive. Because the meta descriptions aren’t displayed in the pages the user sees, it’s easy to let this content slide. But high-quality descriptions can be displayed in Google’s search results, and can go a long way to improving the quality and quantity of your search traffic.

Good luck to your online business.
