Compare the domain listed in AdSense with the address visitors use. Test HTTP/HTTPS and www/non-www variants, and note the final canonical URL. Confirm that verification and code are applied where Google instructs. Google’s site connection guide explains the connection process; the account remains the source for site-specific steps.
Example: AdSense lists the apex domain, but a security plugin redirects to www and a DNS migration left the apex pointing to an old host. Fix the redirect or DNS configuration, then verify the public site and account status. Do not add duplicate site entries without understanding the account workflow.
Run SiteReadyScore for public reachability checks across the live URL. It cannot determine which site entry Google should review or see private ownership status.
