SEO like Advertising is not a single way related to forum content... even if you say the opposite. vBulletin is at first a forum, with some added solutions to suite clients requests...

all of the forums i've seen open lately regarding ads and adsense and seo are closed now, because there is nothing to say (ask Floris, with his own site)... you put ads to your site, you install seo, and tada... what is to be discussed there?!... everybody have a different way to see ads placement, or seo usages... and it was proven even by google that seo is completely useless on private boards and off-topic forums. so what would you say to half the clients of Jelsoft about the content of their site?!... vbSEO team is already trying to build a content regarding seo, and the only thing they can grab is clients testimonials... 50% were opening boards, they could not even compare what was the change before seo installation because they were not having a site to do so...

if you think the subject worth opening a forum, why aren't you starting one ?!
