For Blogger

Advart has a unique way of bringing traffic to your blog. You sign-up for free and its very simple to do that. Once you have signed-up you can create up to 6 ads with a title 3 description lines, choose a category in which it would fit and of course you link it to a url.

Once you do that these ads will be displayed all over other peoples site and blogs all over the net, by how many impressions you have allocate to each of your ads automatically or manually. You receive impressions by posting other peoples ads on your blog. They will give you a url to place on your blog. You may of course get as many ads on your blog as you like.
You will receive 3 impressions for every ad for every time your blog or site loads on a computer screen, easy right. Every time someone clicks one of those ads on your blog or site your ad will be shown until some one clicks on your ad.

 It's recommended that you have a blog. You may also give your favorite program link.
 It's absolutely free. Plus you will get 2500 free impressions. So if you don't have a blog I  recommended that  you signed up.
PS: see the sidebar you find  advart ads under google ads.
