The Inside Adwords blog has announced a cost per click beta pricing model for site targeted campaigns. Site targetting allows advertisers to pick individual websites (who run adsense) where they wish their adverts to display.

At the moment the only pricing model for advertisers is a CPM (cost per thousand impressions), so the plan is to allow greater choice and flexibility by offering a CPC alternative.

The Inside Adwords blog explains-

CPC bidding has often been requested by advertisers who would like to utilize site targeting, but are not comfortable bidding on a CPM basis. Here are two examples of how CPC bidding can enhance your site targeting experience:

* Increased flexibility. Select the content network sites you want your ads to appear on and choose the bidding option that fits your needs. If clicks are your goal, try CPC bidding so you pay only when you get the result you want.

* Full control. Create new CPC site-targeted campaigns, or switch your existing campaigns between CPC and CPM at any time. As always, you retain full control over your budgets and bids.

The trial is only available to US advertisers, who can fill out a short form which can be found here.
