Differentiate between a do-follow and a no-follow link.

Dofollow links are a way to pass on authority to a website, while a nofollow link does not pass on link juice.

Do follow links—we can say that do follow links tells the search engine to visit those links, and it will help the search engine ranking for the website and pass the link juice.

No follow links indicate to search engines that those links should not be followed, and they not help Google's search engine ranking. It does not pass the link juice, but it will help with website traffic.
