I want to create a Wordpress blog with different guides locked with AWM gateway and I'm not sure if it will be hard to get traffic. I mean - it's easier to rank and promote domain connected with keyword, but I want to run a portal with guides, and it definitely won't stand a chance to get ranked as guide site. Can I beat the problem using YouTube Videos and Yahoo Answers to promote niches? Is common site for different files such a bad idea? Or should i try THIS: Subdomains with simple landing pages on common domain, I can afford it and it looks like best idea? Try to help in picking best option.
