What is the difference between dofollow and nofollow links?

Dofollow and nofollow are attributes used in the HTML code of a link to indicate to search engines whether the link should pass on link equity (also known as "link juice") or not.

A dofollow link is a link that passes on link equity and helps to improve the search engine rankings of the linked-to website. When a website links to another website using a dofollow link, it is essentially telling search engines that it vouches for the quality and relevance of the linked-to website. This can help the linked-to website to rank higher in search engine results pages (SERPs) for relevant keywords.

A nofollow link, on the other hand, does not pass on link equity. It is a way for website owners to link to other websites without endorsing them or passing on link equity. Nofollow links are often used for user-generated content, such as comments on blogs, to prevent spam and manipulation of search engine rankings.

In summary, dofollow links pass on link equity and can help to improve the search engine rankings of the linked-to website, while nofollow links do not pass on link equity and are used to prevent spam and manipulation of search engine rankings. It's important to have a balance of both dofollow and nofollow links in your backlink profile to appear natural to search engines.
