In SEO, a “No Follow” link is a type of link that tells search engines not to consider it as a factor when determining the ranking and authority of the linked page. Essentially, it’s a way for website owners to tell search engine crawlers that while they are linking to a specific page, they don’t necessarily endorse it.
When a link is marked as “No Follow,” it means that the website linking to another page is not passing “link juice” or “PageRank” to that page. In other words, a No Follow link does not have an SEO value for the page it is linking to. This is unlike a “Do Follow” link, which passes link equity and can help to improve the linked page’s ranking in search engine results.
<a href="https://example.com" rel="nofollow">Link Text</a>
The “rel” attribute with the “nofollow” value signals to search engine crawlers not to follow this link and not to use this link in calculating the PageRank of the linked page.
No Follow links were initially introduced to combat spam and prevent people from improving their site’s rankings by leaving links in comments on other websites. They are also commonly used when linking to pages that you don’t want to implicitly endorse, such as advertisements or sponsored content.
While No Follow links may not directly improve the search ranking of a webpage, they still have value. They can drive traffic to your site when visitors click on them, and having a natural mix of Do Follow and No Follow links is generally seen as a sign of a natural, healthy link profile.
