A useful tool to have in in your WordPress toolbelt is the ability to quickly and easily search for, find, and replace specific strings of text directly from the MySQL database. We can do this by entering SQL queries either directly or through one of those handy interface applications like phpMyAdmin, which seems like one of the most prevalent PHP applications on servers today.
If you have posts that include the
nofollow attribute on links, you may at some point decide to remove them. By default, WordPress doesn’t insert
nofollow attributes in post content, but there are a variety of plugins that will insert
nofollow into all links in post content. Or perhaps you have been manually adding
nofollow tags to your post links for SEO purposes. Regardless of how they got there, it’s very easy to clean things up and remove all
nofollow attributes from post content.
