Dofollow links allow google (all search engines) to follow them and reach our website. Giving us link juice and a backlink. If a webmaster is linking back to you with this link both Search Engine and Humans will be able to follow you. The best way to give someone dofollow love is allowing keyword in the anchor text. This means when you are linking to any website or page, use the targeted keyword as anchor text.
Dofollow links pass along what the SEO community commonly calls “link juice.” Links are a vote for quality. By learning which webpages are often linked to, search engines can determine how highly websites should rank in search results. Links are just one of many ranking factors.
