The common basis for all Ojooo services is an innovative form of advertisement - the Earn per View Online and Mobile Advertising (EPV) from Ojooo. Ojooo offers companies advertising space and user data through the Ojooo app, as well as the Ojooo portal, based on blockchain technology. It can be advertised both with the help of text advertising, as well as all common graphic advertising formats. The app collects very high-quality user data. Advertisers may gain access to this information upon user consent. This data enables advertising that is optimally adapted to the context and perfectly personalized and thus can have the maximum effect.
