Anyone knows if there's a commercial serp tool available that would do the opposite of what most do? Usually serp ranking tools will help you find the position of one or multiple keywords for a single domain, but I would need that reversed. I would need a tool that supports 1000's of urls to be checked for a single (or multiple) keyword. Do you know if such a tool already exists? Or is it yet to be made? Then please post here. Thanks in advance.
