The `rel=”nofollow”` tag is an HTML feature that tells search engines not to follow a link or give any ranking power to the linked site. Introduced by Google in 2005, it helps website owners manage their links better and avoid endorsing untrustworthy content. This is especially useful for user-generated content like comments or ads, as it keeps spammy backlinks from affecting a site’s credibility while still allowing search engines to see those pages. Overall, it’s a tool for maintaining quality on your website.
