I'm working on a site about Windows 7 now. It proves Windows 7 Wallpapers, Software and Tips for free. I have tried many ways to improve the rank in Google, but it doesn't work. And i have no money to ad it, so i have no idea about it now. Can you tell me how do you submit your site to Google search engine? Thank you every much! PS：What i want to do contains that when somebody search things my site have, my site would appear in the first page, I know it's difficult but I'm trying.
