Hey guys, quality site can be tracted this way (www.veoreport.com) it's the visitor behavior on the site.

For example, google and yahoo as well alexa has toolbars, so they can check every page request by visitor this also means they can track visitor behavior on site, for example, visitor lenght, return visitrs, pageviews per visitor, etc;

I think this is very serious quality score, if they look for "x topic" and they stay on site 20 minutes, this site is good on that topic, but if he clicks and then clicks away, it might be bad for the site quality;

AdSense is not helping much for this approach as it's more like cookie cutter site to just get visitors to click on adsense; and these things could hurt many fast buck makers quite seriously;
