Etology is an excellent new service similar to Project Wonderful that allows webmasters to sell ad space on their blogs or websites for free.
As a publisher you can offer potential advertisers the opportunity to purchase either text or image based advertisements in a variety of standard ad formats, such as 125x125, 468x60, etc.
With this program, the sky is really the limit as to how much a publisher can earn. A lot of other programs decide how much your ad space is worth, thus greatly limiting your earning potential. With Etology, you decide how much your ad space is worth!
In addition to selling ad space, publishers can advertise as well. Earnings can be credited into your account allowing you to purchase advertising while selling ad space on your blog at the same time!
The minimum payout rate is $30 via check or credited to your account. Where as international publishers are paid via check, PayPal, Epassporte, or bank wire.
Overall, Etology is a promising advertising service giving bloggers and website owners a chance to monetize their empty sidebars.
