So, once terminated the main parts of this system, i've posted a comment on html.it blog to make the search engines able to enter my site.  I've choosen that blog because is one of the most visited blogs in Italy so crawlers should be able to come earlier. In fact, Googlebot came only 12 hours and 51 minutes later on my home page. Exceptional. Yahoo came only 26 hours and 21 minutes later. In this exact moment Yahoo has visited just 4 pages while Google has visited all the pages. There is nothing to do. Google is superior. The are no companies at the same level of Google.
