Why not ? A forum is a grate place to exchange idea talk and share stuff . why not having a grate Seocheckout forum .
can we exchange service that worth same prices ? let say i am offering 40$ VPS 8 core for seo job. and i will exchange it for a buyer who offer 1000000 youtube view . can we do that ?
can we offer a local services and we use this site to safe our payments ?
how we target? traffic using a good keyword. how we can know it's good one ? ?
