Nofollow Case by Case is a WordPress plugin designed to enhance the management of comment links on your site. This free tool allows users to convert nofollow links into follow links on a case-by-case basis, which can be beneficial for SEO. Users can easily modify comment links by adding '/dontfollow' to the end of a link, ensuring that potentially valuable links are not lost due to spam concerns.

The plugin performs several automated tasks, including removing unwanted attributes like rel="nofollow" and rel="external" from comment links. It also ensures that external links open in new windows, enhancing user experience while maintaining semantic correctness. For those looking for additional features, an NFCBC SEO Plugin ADD-on is available, which aims to simplify comment management further.
