What is the difference between a do-follow and no-follow and how are they used?

“Nofollow” and “dofollow” are attributes used in HTML to control how search engines follow and index links.

A “dofollow” link is a regular hyperlink that allows search engine bots to follow the link and pass link authority from the source page to the target page, potentially improving the target page’s search engine ranking.

A “nofollow” link, on the other hand, instructs search engines not to follow the link and not to pass any link authority. It’s often used for user-generated content, paid links, or to prevent link spam.
