If its for the site in your sig then $350 wont do shit man.The type of site you are trying to get search engine traffic for is very,very hard to do.Takes 12 months of hard work and planning.
For some reason everybody wants to copy Jays or Hoes and they haven't a clue what it entails.If you are new to the game of SEO start of with a smaller niche siteand use plenty of original text.Don't just fill it up with links.Stop chasing the "free porn" words and get some decent original pic content.Make it a site worth linking to and then find other related quality sites with minimun outbound links on it and trade links with them.If they wont trade with you because you have no pr then buy a couple of links to get some pr.With that $350 you could've had a pr5 for 2 months.
Then when you have done all that the hard work begins and then you hire a SEO like myself
for $200 hr to give you the edge over the thousands of others doing the same thing.
