nofollow
attribute appeared in the page-level meta tag, and instructed search engines not to follow (i.e., crawl) any outgoing links on the page. For example:<meta name="robots" content="nofollow" />
nofollow
was used on individual links, preventing robots from following individual links on a page required a great deal of effort (for example, redirecting the link to a URL blocked in robots.txt). That's why the nofollow
attribute value of the rel
attribute was created. This gives webmasters more granular control: instead of telling search engines and bots not to follow any links on the page, it lets you easily instruct robots not to crawl a specific link. For example:<a href="signin.php" rel="nofollow">sign in</a>
nofollow
causes us to drop the target links from our overall graph of the web. However, the target pages may still appear in our index if other sites link to them without usingnofollow
, or if the URLs are submitted to Google in a Sitemap. Also, it's important to note that other search engines may handle nofollow
in slightly different ways.nofollow
:
nofollow
attribute on links posted by members or users who have consistently made high-quality contributions over time.nofollow
on such links. Search engine guidelines require machine-readable disclosure of paid links in the same way that consumers online and offline appreciate disclosure of paid relationships (for example, a full-page newspaper ad may be headed by the word "Advertisement"). More information on Google's stance on paid links.nofollow
on these links enables Googlebot to crawl other pages you'd prefer to see in Google's index. However, a solid information architecture — intuitive navigation, user- and search-engine-friendly URLs, and so on — is likely to be a far more productive use of resources than focusing on crawl prioritization via nofollowed links.<a href="http://blog.example.com" rel="me">My blog</a>
However, because these links are user-generated and may sometimes point to untrusted pages, we recommend that these links be marked with nofollow. For example:
<a href="http://blog.example.com" rel="me nofollow">My blog</a>
With
rel="me nofollow"
, Google will continue to treat the rel="nofollow"
as expected for search purposes, such as not transferring PageRank. However, for the Social Graph API, we will count therel="me"
link even when included with a nofollow
.nofollow
link.
