Directory submission is the process of submitting or listing your company in internet directories in order to increase the likelihood that it will be discovered by people conducting online searches.
That’s what a DoFollow link is. The term “DoFollow” is used to refer to links that Google and other search engines will follow to visit the connected website. As a result, the linked-to website gains credibility, sometimes known as “link juice,” from its original source.
Links with the “follow” attribute are given more weight by search engines, increasing the page rank of the destination website and increasing its visibility in the results.
