AdKeeper was an online advertising platform that allowed consumers to keep online ads for future use. A button is inserted into advertising creative elements, and is visible to users as a small button in the ad with the letter “k” inside the button. Consumers can 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 have kept. The users can also share ads with others, via email or social networks.
