hello, does anyone knows what are google criteria to index forums when you search within google.com --> press "show options" under the search box --> and choose "forums" ? when i search for a specific forum normaly (google.com), my forum is in SERP, when i search it with the method mentioned above, i don't get any reasult. i wonder how it works....
If you can see your site normally in results, then its google indexed. But, you have to optimize your forum for the keyword "forum" to get a high ranking in that option.
