For some time trying to find out what tools use some webmasters to get their back links on different sites with PageRank, visible only to search engine bots. For example : This affiliate link has in yahoo more than 15,000 back links: livejasmin.com/listpage.php?tags=girl&psid=thierto When I go and look for affiliate Urls in the HTML of the sites where it appears to have back links, but this does not exist. What tool does this type of work? Does anyone know?!
