AdToll pays on a CPC basis. Their user interface is great and navigating through the user panel is both easy and pleasant. Payments are available via Cheque, Paypal, ePassporte and Wire/Bank Transfer. It is also possible to use the revenue you earn as a publisher to advertise your website further. Such integration is something that is entirely missing from Google's adsense-adwords.
The newest technology by AdToll is a Peel Away Ad technology that shows a peel on the top right hand side of a web site. When the mouse moves over the peel it opens smoothly to reveal the advert within. This new ad format allows you to make use of the lesser used, yet highly visible top corners of web sites. It is very non intrusive to the site visitor. Since it uses a small amount of space, it is efficient use of web site real estate. An additional plus is that such a new advertising format always draws curious clicks for visitors.
