Google Ads is facing a rare bug that has led to over-reporting of click-through rates (CTR), prompting concerns from advertisers. Brad Geddes highlighted the issue, noting an ad group with an anomalous 107% CTR, while some search terms showed even higher rates. Ginny Marvin, the Google Ads Liaison, confirmed the issue, stating it occurred due to invalid clicks being processed later than their corresponding impressions. Despite the rarity of this issue, it remains unresolved as the Google team works on a solution.
I'm looking at an ad group with over 3,000 impressions and a 107% CTR. The highest CTR search term is 1000%.
It was a rare instance when invalid clicks were processed at a later date than the corresponding impressions.
For a period of time, the reporting reflected clicks without corresponding impressions and thus the >100% CTR.
This is a rare occurrence and the team is looking to mitigate it altogether.
