Hello,
What is the difference between do follow and no follow links?

Dofollow Links do pass the link juice while nofollow ones don't pass it on

Dofollow links are those links which do not contain Rel=”Nofollow” attribute. These links have the potential to improve the ranking & credibility of your website in search engines. If a webmaster is linking back to you with this type of link, then both Search Engine and Humans will be able to follow you.

Do follow and no follow are link attributes and contain instructions for search engine robots. Do follow links are crawled and indexed in search engines whereas no follow links are never crawled and indexed in search engines.

Do-follow backlinks help in traffic & backlinks both while No-follow links in traffic only.
