 One of the users of the service, Chris, Alex (Alex Chris), wrote in Twitter'e, that "many AdSense publishers say about the abnormally high growth index CTR for the last two days" . Some of them reported about 5,000 percent increase in CTR. In numerous forum discussions publishers have expressed their concerns about the possible penalties and sanctions for abnormally high numbers CTR. Fortunately, a strange surge observed by many users of the service. According to Barry Schwartz (Barry Schwartz) of the Search Engine Roundtable, this situation may be due to an error in reporting or to some other, more serious, cause. Google representatives have not yet provided comments on this issue. Recall that in January this year publishers also observed jump in CTR ads. At the time, it occurred after the update site design. This situation has raised concerns among publishers that Google may pay attention to it and count fraudulent changes, and then close the account and keep any future expenses / revenues.
