hi,
Before explaining something, i would like to tell you that, to get your forum, rank in first 10 positions and to get high traffic, there are other things apart from vbseo, on which you have to think on.
What vbseo do - is to create regular sitemaps, and generating static urls. Your sites pages will take weeks to index on google. It all depends on how big your forum is. I already implemented vbseo, and getting great results, but with vbseo i'm also implementing seo things and page managements like..
I can offer the same thing to you, with 100% success. But optimization cannot to be seen in 24hrs, it will take atleast 2-3 months. Our rates are on per month basis. More on vbseo can be explained w.r.t what exactly you want..apart from seo and ranking. and ofcourse getting indexed.
