Hello Guys, Today I logged into my account and got the following message "Your ads have recently appeared on websites you haven't authorised. To avoid lost revenue, make sure that you authorise any sites where you display ads by visiting your account settings" I have updated the setting and everything is verified but I still get the message it says the last crawl attempt was oct 7th how often will google attempt to crawl my site so that this message dissapears and they update there system?.
