We'll create fresh WordPress site with SEO SearchTerms Admin installed. You have 20 minutes to test the plugin after that site we'll be deleted.
This simple plugin will list all the incoming search terms generated by SEO SearchTerms Tagging 2 in a metabox under the post editor. This way you can easily use these incoming search terms to find potential keywords and update your content accordingly.
A simple tick or cross will indicate if the term is already present in the post content (using case insensitive match).
You will need to have SEO SearchTerms Tagging 2 in order to make this plugin work.
