No-follow links are hyperlinks with a precise HTML tag instructing search engines not to transmit any form of "link juice" or SEO value to the referenced site. Though users can click on the link and reach the target webpage, search engines, such as Google, will not consider it an endorsement of the authority of a particular website. To avoid manipulating search engine rankings, no-follow links are commonly used for outward links in comments, forums, or advertisements. Sometimes, no-follow links are intentionally used by websites to prevent passing SEO value to other websites.
Several reasons advocate for the application of no-follow links. One main reason is to avoid the excessive manipulation of search engine rankings through link building. By marking certain links as no-follow, website owners can prevent giving poor quality and untrustworthy sites any SEO benefit. This is particularly advantageous in user-generated contexts such as blog comments, forums, and social media posts that often comprise spammy links.
In places like blogs and online discussions, no-follow links tend to be more prevalent than ever before. Blog comments and forums often entail vast amounts of content created by individuals who visit them. Those high traffic blogs and forums also carry a lot of domain authority with search engines. A link from one of those blogs or forums can help boost the referenced websites’ authority.
Back when the blog was quite new in the early ages of the internet, posting a comment on another website to link back to your own website was a common way for new bloggers to build link equity by leveraging the authority of established websites. This tactic became abused by spammers who would comment on a multitude of blogs to quickly build link equity.
Hence, blog comments and forums increasingly default to no-follow links, if links are actually allowed. No-follow links help to avoid search engine optimization (SEO) being hampered by junky or inferiority kind of links. Websites can turn on no-follow tags in order to retain some form of control over their services. Even if some hyperlinks are still manually added to the comments section, those links won’t accrue any SEO benefit whatsoever in their eyes.
Websites that host sponsored content or advertisements typically use no-follow links. This practice aligns with search engine guidelines to avoid passing link equity for paid links. For instance, if a blog post includes a paid promotion or affiliate link, it should be marked as no-follow to prevent it from unfairly boosting the linked site’s search rankings.
Social media platforms and other user profile-based websites also implement no-follow links extensively. For example, links in social media posts, bio sections, and user profiles are usually no-follow to prevent users from exploiting these platforms to manipulate SEO rankings. This practice helps maintain the credibility and fairness of link-building efforts.
Many news websites and press release distribution services use no-follow links for external URLs. This helps prevent any unintended SEO benefits from being passed to the linked sites, especially since these articles can be widely distributed and syndicated. By using no-follow links, these platforms ensure that the focus remains on delivering valuable content rather than influencing search engine rankings.
There are several situations where utilizing no-follow links can be more beneficial. If you wish to reference an untrustworthy website or one whose promotion you don’t desire, opt for a no-follow link. As per Google’s recommendations, almost all paid links or ads have to be created as no-follow so that link equity does not pass on to them. Likewise, no follow links are commonly preferred in affiliate marketing and promoted posts for search algorithms transparency and equality purposes.
No-follow links should only be used where they make sense in order to keep your linking strategy clean and honest. You should regularly check your site’s outbound links so that you will always know if the no-follow attributes are applied correctly. The purpose of this is to uphold the SEO integrity of your website and also to adhere to search engine rules.
