I recently noticed that when I look on the cache version of my frame based homepage (and some other sites like snookerusa.com) I no longer see the blank page ,or the content of the NoFrame that Google normally displays for pages with frames. What I see in Google cache version of the homepage is the content and meta tags of the page that is loaded to the inner frame. Does anyone know may be the cause of this or what possible implications it may have on the site's performance?
If you look at the source code of snookerusa.com (I can't give my site company's site) you will see that it has only a frameset and a noframe section. Up until now Google only showed the NoFrame section but now when I look at the cache text version of the page i see the content and metas of the page that is loaded to the frameset (snookerusa.comnews/home.php) and not the content of the homepage. Is Google treating frames differently now? or is there a reason why this site is treated differently?
