There are different definitions of a click depending on the advertising platform, so we need to check that we are talking about an outgoing click, which therefore brings traffic to the site. The difference may also be due to different tracking, such as a redirect to an untracked page. There may be clicks that are lost, and therefore not visited, because they are blocked by adblockers, or that lead to a page that does not load, or that are made by bots, and therefore excluded from the traffic. When faced with a huge difference, you need to take stock of the situation with the advertising platform to understand how it works and thus reduce the economic impact of the CPC.
