AdWords is to be added new features – site targeting and cost per impression bidding – which will allow advertisers to tune their campaigns more accurately. These new features will be in beta testing for the next few weeks.

Site targeting allows the advertisers to choose the sites they wish for their ads to appear within the Google content network. Site targeted ads will not be displayed on other websites than the ones the advertiser chooses. The advertisers have thus the opportunity to decide by their own judgment the relevancy of their ads on one website or another – a feature they’ve long waited for.

Content targeting will work separately of search engine keyword targeting. Search engine placement algorithms will remain unchanged.

However, content targeting still left a problem unsolved: how do the advertisers pay for the placement of their ads? Google offers a cost per impression bidding model.

Similarly to the PPC bidding on AdWords, the advertisers can set a maximum amount of money they are willing to pay for the thousand of impressions they get being on a certain site.

For the first time in its history, Google allows image ads and animation in the ads – an aspect that it has permanently disapproved in web advertising up to this moment.

The minimum bid for a thousand impressions per ad is $2, and from there the sum can go up and high, depending on the competition it gets from other ads.
