1. Received an email: Ad serving limits placed on your AdSense account. Dear Publisher, Hello! We recently found invalid traffic issues in your AdSense account. For this reason, we have placed ad serving limits on your account. We will continue to monitor your traffic and will automatically evaluate and update this limit accordingly. See Figure 1
2. View details in the Google AdSense Policy Center. Ad serving limit start date June 25, 2023 Current status Due to invalid traffic issues, your account’s ad serving is currently limited. See Figure 2
3. In Google AdSense reports, starting from June 25, 2023, pageviews remained unchanged, but ad impressions dropped drastically. See Figure 3
4. There is currently no appropriate solution, because I did not intentionally generate invalid traffic. The email states: This type of ad serving limit typically affects publishers for no more than 30 days, but in some cases, it may take longer. I decided to wait 30 days before continuing to observe ad impressions. See Figure 4
5. After waiting for about 10 days, the ad serving limit has been lifted, and ad impressions have recovered to the level before the limit. See Figure 5
