"Nofollow" provides a way for webmasters to tell search engines
"Don't follow links on this page" or "Don't follow this specific
link." 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> How
does Google handle nofollowed links? In general, we don't follow
them. This means that Google does not transfer PageRank or
anchor text across these links. Ess
