The idea of this thread was for everyone to add input for SEO tips. e.g the first person to responds says 1)don't buy recipricol links. And then we go from there. Just aiming out helping those people who know nothing about SEO.
first read http://forums.digitalpoint.com/showthread.php?t=413544 and second , focus on backlink building as much as you can do
Content, content, content! There are a lot of SEO techniques out there, but if you build a quality website, visitors will visit once and stick around for a while. Simple SEO tips are all over the place here, but if you build a crappy website that users don't like, then all the SEO in the world won't matter.
Pay less attention on keyword density. The idea is getting out of date. Meta tags are also getting less and less importance according to SEs.
