Top Online Advertising Verification Services

List of online advertising verification products and services. Online ad verification involves placing ads along with a bit of code (usually javascript) that reports back information and data about not only the ad's performance but the users looking at that ad. The goal is to allow marketers and advertisers to make quick decisions about the efficacy of an advertising campaign, and to make changes if necessary. (A good example would be an advertiser who only wanted to advertise to a certain demographic - say, people living in Los Angeles. Ad verification can show them how many users saw the ad who were or were not living in that geographical area, so that they can measure the effectiveness of the campaign compared to their goals and evaluate their working relationship with the publishers or ad networks.

Some of the advertising verification companies included on this list are DoubleVerify, Mpire and TagMan.
