On the internet, all links are considered Dofollow unless they are assigned a Nofollow attribute.
In the past, paid advertisement links and comments were tagged with the nofollow attribute. This let search engine algorithms know that the link should not pass any link equity (or “link juice”) and should not be considered in rankings.
Initially, Google recognized two types of links: dofollow and nofollow. The idea was that Google would follow dofollow links and pass link equity, while nofollow links wouldn’t pass any link authority.
However, since March 2020, Google has changed how it handles these links. Now, both types of links are considered “hints” for the algorithm. In practice, though, it still seems that the number and ratio of dofollow links hold significant weight.
An example of a standard Dofollow link:
<a href=”https://ad-ops.hu/en”>Click here</a>
The same link in Nofollow form:
<a href=”https://ad-ops.hu/en” rel=”nofollow”>Click here</a>
When analyzing a backlink profile, a healthy profile typically has a higher proportion of Dofollow links compared to Nofollow links.
