Ultimate Blog Marketing

When Adsense was first available, publishers needed to have access to a website which they controlled, that is, they needed to have their own registered domain and url. Now there are more opportunities to make money with adsense even if you don’t own your own domain.
(1) Creating a free blog on Blogger. Since Blogger.com is owned by Google, it integrates seamlessly with Adsense. If you apply for an Adsense acct using a Blogger blog as your website, be sure you have enough content on your blog or else your application might get turned down.
(2) Adsense revenue-sharing article directories. The big 3 are Infobarrel, Xomba, and Hubpages. If you post articles on these sites, you can have your own Adsense ads displayed on the articles too and generate extra money. Plus you keep the rights to everything you write as long as it is your own unique content.
To date, Myspace and Facebook don’t let you customize your pages with adsense ads (at least not the last time I tried, I haven’t logged on in several months and I never used either site very much) but someone can correct me if I’m wrong.

you can put those ads into every site or blogs you own.
