Reminder: Your subdomain blocks will be promoted to the domain level in 3 days.

If you use Google AdSense to monetize your website, you may have received a notification that reads, "Reminder: Your subdomain blocks will be promoted to the domain level in 3 days." This message is important to understand because it affects how your blocking controls work.

Reminder: Your subdomain blocks will be promoted to the domain level in 3 days.

Essentially, any blocking controls that you have set up for a subdomain (such as blog.example.com) within your AdSense account will now also apply to the entire domain (example.com) instead. This change is part of the Sites tab changes in AdSense, and it is set to take effect in three days from the time of the notification.

For example, if you previously had specific blocking controls for a subdomain, those settings will now also apply to the main domain. This means that if you had blocked certain types of ads on your subdomain, those same types of ads will also be blocked on the main domain.

It's worth noting that any blocking controls for subdomains that are visible at the top level of the Sites table will remain unchanged. This means that if you have specific blocking controls set up for a subdomain that are already visible at the top level of the Sites table, those settings will not be affected by this update.

Overall, it's important to be aware of these changes and to check your blocking controls to ensure that they are set up correctly. By doing so, you can help to ensure that your website is displaying the types of ads that you want, and that your users are having a positive experience on your site.
