What  are Nofollow links?

Nofollow is an HTML attribute value used to instruct search engines bots that a hyperlink should not influence the link target's ranking in the search engine's index.

"Nofollow" provides a way for webmasters to tell search engines "Don't follow links on this page" or "Don't follow this specific link."

Originally, the 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" />
Before 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>

A no follow link is a link that does not count as a point in the page's favor, does not boost PageRank, and doesn't help a page's placement in the SERPs. No follow links get no love. Theirs is a sad and lonely life.

A no follow link is created with the nofollow link HTML tag, which looks like this:

<a href="" rel="nofollow">Link Text</a>

The nofollow tag is basically a notice sign for search engines saying "don't count this."

Isn't that just mean and terrible? Why would anyone do such a thing? There's a reason for the nofollow attribute, and boy is it a good one!

A Nofollow link refers to backlinks that tell the search engines to not go any further, hence "nofollow". By adding the no follow tag in a backlink, these links don't transfer link juice. Remember that link juice is what determines Page Rank, and the more link juice you have, the higher the page rank a page has.

No-follow links means it tells the search engine don't follow those links so search engines give less importance for this kind of links.

No follows links are doesn't passes the link juice.

The no follow links are not crawled by google bots and those links does not pass any link juice to your site from where the back link located.

Nofollow links are links with a rel="nofollow" HTML tag applied to them. The nofollow tag tells search engines to ignore that link. Because nofollow links do not pass PageRank they likely don't impact search engine rankings.
