What is rel="nofollow"?
A nofollow tag is used to tell search engines not to count a link to another page as a “vote” in favour of that content (and therefore not to count that link towards the page’s search ranking).
Nofollow tags are often used to prevent search engines from thinking you are involved in link-building schemes they deem to be unacceptable. For example, you may use nofollow tags in sponsored content, to avoid penalties related to paid-for links.
The evolution of rel=”nofollow”
Since its introduction in 2005, Google has not counted any link marked with rel=”nofollow” as a ranking signal.
The update to nofollow will now mean that it’s treated as a ‘hint,’ rather than a complete block, about which links to consider or exclude as ranking factors. In short: nofollow links will no longer be ignored.
The nofollow attribute will continue to work as it does now until March 2020, from then on, it will be treated as a hint.
The new link attributes
Two new link attributes have been introduced. These will both also be treated as hints, and are already in effect:
rel="sponsored" - Use the sponsored attribute to identify links on your site that were created as part of advertisements, sponsorships or similar agreements.
rel="ugc" - Use the UGC attribute to identify links that appear within user generated content, such as comments and forum posts.
Don’t worry about changing all of your existing nofollow links. Google will continue to honour the attributes already in place. Moving forward, Google prefers the use of “ugc” and “sponsored”, but nofollow will still work as well.
Where appropriate, you can also use more than one attribute per link. For example, if you are linking to sponsored content that appears within user generated content, the link attribute rel=“ugc sponsored” would be valid.
According to Google, there’s no ‘wrong’ way to use the link attributes except in the case of sponsored links (which must use rel=“sponsored” or rel=“nofollow”.)
