Hello, Would the following strategy give good results? Lets say I create a WP plugin that would be useful for adult wp blogs, make it available for free, but ask plugin users to have a link to my site in order to use the plugin. Is that considered as white hat SEO? What good would that make for my site ranking? If my plugin is fairly useful, would this thing work? Is something like this already available? It could probably be used on Joomla, as well. Same is true for all opensource CMS-es.
