The nofollow attribute on a web page hyperlink instructs search engines not to use the link in page ranking calculations. It was initially proposed to combat comment spam on blogs.

The authors copyrighted the nofollow specification in 2005–07 and it is subject to a royalty-free patent policy, such as the W3C Patent Policy 20040205.

The standard was originally developed by Google however has since been adopted by many major search engines like Bing, Yahoo!, Yandex and Baidu.

Nofollow links still pass value however are designed to not pass as much power and infer that the website doesn’t necessarily endorse the link.

Example code:

<a href=”” rel=”nofollow”>Link text</a>


This refers to all other links that don’t make use of the nofollow attribute and pass maximum power to search engines.

It is also used for best practice with affiliate links in order to prevent the flow of pagerank and is a commonly accepted standard by search engines for this purpose.

Nofollow UGC (User-Generated Content)

This is a variation of the nofollow standard and clearly tells search engine that the content was created by an independent user and not published directly by the website.
