Google adds a new level of granular blocking for AdSense for content. "With site-level blocking, you can block by URL; if sensitive and general category blocking are available in your language, you'll be able to apply these options as well," google wrote.
Adding, "there's a product-wide limit of 500 URLs that can be added to a block list."
To get started with these new flexible controls follow the two steps, once they're enabled in your account:
Site management: To take actions on a site-level basis, Google says publishers must first tell the AdSense system of about "which domains and subdomains they own."
To do this, "under 'Home' tab, visit the 'Account Settings' page and navigate to the 'Access and authorization' section. From here, you can create Owned sites list which already contains domains from existing URL channels and manually add further domains or subdomains," explains google.
Or, "publishers can also claim a site from an automatically populated "Unclaimed" sites list, which shows all sites where your ads are receiving impressions," google added.
"Owned sites list will now appear under 'AdSense for content' in the navigation bar."
"Note that manually entering subdomains into the list will enable you to block ads from those specific pages while still allowing the ads to appear on the top-level domain."
Site-level blocking: Once Owned sites list is set up, publishers can visit 'Allow and block ads' tab. To block ads from a specific domain or subdomain, "just select it from the list in the left-hand navigation and make updates. If you'd like to apply any blocking changes to all of your sites, just select 'All my sites' from the left navigation," google said.
Also, the Allow and block ads tab now has some updates, including "a new navigation bar, new horizontal tabs, and an option for site-level blocking."
