In December 2023, I opted to adjust the 'Vignette ad frequency' from 10 minutes to 1 minute, aiming to see if it would boost my revenue. This change led to an increase in Vignette impressions from 1,000 to 5,000 per day. Despite this surge, the RPM fell from $10 to $2, leaving my daily revenue unchanged.
By February 2024, I chose to revert the 'Vignette ad frequency' back to 10 minutes to avoid disrupting users. I did this through the 'Ad Settings Preview' in the AdSense dashboard, specifically under Overlay formats. However, even after making this change, the AdSense reports still show 5,000 Vignette impressions per day instead of the expected 1,000, along with the lower RPM.
Despite the dashboard displaying the "10 minutes" setting, it seems to be ineffective. What am I doing wrong? I want to show lower number of Vignettes to get the same income without disrupting users.
