I have my own domain saved in the Allowed Sites in adsense. Also google.com , google.com.au , etc. and only allow the saved sites to show ads for my account. What I am not sure at all is; in the Unauthorized Sites list there appear still a several IP's that belong to Google (when opened in browser the IP's take me to Google search). Should I add these IP's into the Allowed Sites list? They must generate clicks if they show among unauthorized sites. What's better to do? Thanks!
you can add these sites in your allowed sites list but i was told that it is nearly impossible to add all of these IPs because there are over a hundred of them. if you don't add them, you may be losing revenue on some clicks. some site owners don't worry too much about this cause when they look at their stats, the visitors on these pages are not too many. this seems to be an issue that is hanging in the air.
Those are the cached browser pages. Most people who look at them instead of the main link probably don't click ads either.
