I'm looking for a WordPress plugin that will insert a random code (text, banner, link, etc.) after every existing and future blog post. The idea is to rotate your profile links on some well-indexed blog in order to get them indexed. Example: 1. We have 10000 profile links (vBulletin, SMF, PHPBB profiles or whatever). 2. We spread them over 1000 already indexed blog posts (10 random profile links under every post). 3. Once we got the profiles indexed by Google, we remove them from the blog posts. Repeat steps from 1 to 3 to index an infinite number of forum profiles There should be a WordPress plugin that do that. Which is it?
