After googling "improve user experience", how to increase "eCPM" - Lin Wang Blog

Previously, we discussed the joys and concerns of modifying Google AdSense ad click formats, and mentioned that Google's effective click-through rate (CTR) might decrease. However, don't worry—here are some moderate optimization strategies to increase your effective clicks and improve your eCPM. In practice, Google’s previous high impression volume often resulted in a relatively low actual click-through rate, leading to a very low effective eCPM. After consulting with Google AdSense, they suggested I remove Google ads from certain pages and moderately reduce Google ads on other sites as well. Additionally, we made appropriate adjustments to the position and size of the Google ads, moving and enlarging them as needed. Furthermore, for controlling ad display, it is important to use the Google AdSense Preview Tool effectively to limit ads that are irrelevant to your website content. As a result, the eCPM improved significantly!
