My CTR has been droping since January. July was only 50% of January. I have not done any major changes to my sites. What's wrong? Anyone has similar experience?
Maybe you now displaying irrelevant ads? For example, your website is about credit card debt, but Google triggers only ads related to flowers and house cleaning services.
a lot has changed since january for one google has been acting very strange, they have de-index a lot of webpages. reducing the amount of traffic most website usually get.
