I'll start with the fact that a-ads reduces performance.I have a website pythonpedia.ru and I decided to monetize traffic from them.the yandex.metrica counter is running on the site, so according to Yandex statistics, there are 800 unique users in 24 hours, and according to the a-ads statistics, I have only 65 unique users.I do not know where 735 more people have gone.The next day, I had 690 units and a-ads showed statistics of 35 units.I turned to tech support, they never answered my question.They replied that he did not know about such as serfs Yandex continents and Google atletica.How do they think I don't understand, I think some kind of a-ads is strange
