AdKeeper was an online advertising platform that allowed consumers to keep online ads for future use. A button was inserted into advertising creative elements, and was visible to users as a small button in the ad with the letter “k” inside the button. Consumers could click on the k button to keep the ads, and then return to the cloud-based Adkeeper at a future time, to review the ads they had kept. The users could also share ads with others, via email or social networks.
