Google AdSense has introduced two new features to improve site ownership verification. The first feature allows for real-time site ownership checks, which makes it faster and easier for Google to verify ownership when a new site is added to AdSense. The second feature is a new verification method that allows users to add a meta tag instead of using the AdSense code snippet, making it possible to display ads on all pages except the homepage. These improvements aim to streamline the verification process and prevent unnecessary delays. Additionally, Google AdSense has made other changes including enhancements to the ads.txt section and the ability to request a recheck of the ads.txt file.
