A dofollow It is a link that a search engine spider must follow to crawl a web. However, "dofollow" is not an actual attribute that a link receives, because the purpose of a hyperlink is for both trackers and visitors to follow it. The opposite of dofollow is nofollow, which can be deliberately added to a link. Dofollow links convey link juice and PageRank. It is for this reason that these backlinks play an important role in link building or link exchange.
Background
When the Internet was still in its infancy, search engine provider algorithms and indexes weren't as elaborate as they are now. Therefore, it was important that websites reference other websites in the form of hyperlinks. From this dynamic, users were able to discover new web pages and web content, and search engine robots were able to discover other web sites.
The default setting "dofollow" corresponds to the natural link on the Internet that could be thought of as a true global digital data network, growing and progressing solely through its cross-references. Hence, possibly no one deliberately spoke of "dofollow links" in the 1990s, since this was the foundation of a working Internet.
But in the early 2000s, SEOs discovered that the placement of websites in the SERPs could be positively influenced by linking or backlink building. To date, backlinks are used to strengthen domain popularity or link popularity. Until a few years ago, blog comments or forum links were used massively to create backlinks. Automated programs can create thousands of backlinks at the same time. The result was spam on forums and blogs.
The rel = »nofollow» attribute was introduced as a means to consciously prevent crawlers from following a link and to specify that the juice link should not be transmitted with a backlink. Links marked as such will not be included in the evaluation of a website's link profile, according to the official statements of the search engine provider.
The term "dofollow" was created based on "nofollow" to specify a backlink. However, "dofollow" is not a separate link attribute, as is often mistakenly thought.
SEO benefits
The benefits of dofollow backlinks are indisputable in SEO circles. Hence, dofollow remains the preferred link building option to strengthen domain popularity. However, it is increasingly important to evaluate incoming backlinks in terms of various factors such as content relevance or bad neighborhood. And since Google offers inbound link devaluation denial feature in Google Search Console, every SEO should be aware that quality is more important than quantity in terms of backlinks. Since the Google Penguin update, the text of the links is also crucial for the quality of the dofollow links. Any webmaster should strive to keep their link profile as natural as possible, so as not to run the risk of being classified as spam based on fake dofollow links.
