The advertising industry has faced a lot of problems, to a greater extent, when it comes to the accuracy of statistics. Advertising platforms, when counting clicks, usually give distorted statistics, it is difficult to distinguish live users from bots or hired "clickers" who artificially "wind" advertising statistics to charge increased fees to distributors. We offer a solution that "Cleans" traffic and improves quality. Advertising platform DiPlex.online developed its own digital placement algorithm, on the Blockchain technology, which has no analogues in the market. Using our technology, advertisers interact with an active and interested audience. Blockchain technology eliminates unnecessary intermediaries, which allows advertisers to increase the price for a thousand impressions, and companies will be able to directly reward the target audience for viewing advertising, bypassing the process of buying advertising at all. After all, the market is designed in such a way that advertising for a product or project is a mandatory attribute of productive work, so often third-party advertising services unreasonably increase the price for advertising services. User data is highly valuable, especially when it comes to online advertising, as the user purchase and search history reflects the behavior of specific customers, leaving invaluable hints. Blockchain technology transmits this data to the network as a whole, unlike a centralized system, where data is stored on secure servers of companies and used for commercial purposes by interested parties. The creators of advertising will not stand aside, using our algorithm and getting access to a huge array of relevant data already tested by other participants and the blockchain in particular, while advertising targeting becomes much more accurate and cheaper.
