Follow My Links is a very simple plugin that prevents WordPress from automatically adding a “rel=nofollow” attribute to the following two categories of authorial links: 
1. links in the post author‘s comments; 
2. links to the post author‘s URL (usually linked to from the comment author’s username).

Follow My Links

Do not automatically add the rel=nofollow attribute to links in authorial comments, strip nofollow from links to the post author's web page.

Simple plugin that will improve your onsite SEO a bit and make all links from the comment section dofollow, if they point to your own domain. Other links that point to external websites will remain nofollow. WP DoFollow Comment Links don’t have any configorations – simply activate it and that’s all.
It also works with WordPress installations that reside in a subfolder. For example, WordPress installed in example.com/blog, separate from the main website example.com.
