Bidvertiser can be a useful alternative to Google and offer some intriguing ad formats including what they refer to as free design. This lets you specify the look and dimensions of your text ads. While a useful feature I have not investigated how well it works but imagine that while it sounds good on paper it could result in lower priced ads being displayed. I.e. most advertisers will probably want to keep control of the layout of their ads and so turn off support for Free design ads.
Bidvertizer pays you either in $25.00 increments by check or $10.00 increments by PayPal.
Customize the layout of your ads: BidVertiser gives you a simple point-and-click tool to help you customize the layout of the ads to fit your site's look and feel, in order to retain the high quality of your website. Bidvertizer also offers the opportunity to block unwanted ads. The reports provided by Bidvertiser are adequate but not outstanding. The only real problem is that they can be picky with who they accept into their program and can be quick to ban users whose websites show what may be perfectly valid fluctuating visitor behaviour.
