New here and Need Help in “Natural SEO”!

I own and operate two sites for fun. If possible I may be able to get a business' to place ad's on my site. Like I said these sites are for fun not profit. I want to get more members though. How do I get my sites to pull in more members with search engines. Are there any tricks you could show an average person to make their site more visible. I have been able to figure out quite a bit from hands on experience as far as operating the sites goes. I thought it might be more than I could handle but sar far so good. Thanks ahead of time for any help you may be able to give.
Thanks again

If you want to pull members from SEO first your site must be visible from SEO's. You can target a particular keywords and optimize your site on it. You can learn a lot from these forum on how to do that but it takes time.
I also suggest you a site called Natural SEO, This site can help you a lot..
Goodluck and welcome!

The best way to rank in the search engines is to have a niche specific site that is optimized for certain keywords relevant to your niche
You also need to generate backlinks from relevant sites
Also frequently updated content that is unique really helps

Optimize your titles and the links. Change the meaningless page3.htm into internet-marketing.htm

I've been posting video with the highest degree of success for google spiders. The more you post keywords in lots of places the better.
