We are running an Adwords campaign for this client since 5 months. There is a very strange bug that we need to resolve. Our client is unable to see the ad on the results page; however we are able to see all the other competitors. This problem only occurs when testing from the client headquarters and other remote locations on the same corporate network. Geo settings and budget are OK, we tested with them and we were unable to provide an explanation.
It can be IP exclusion, however I don’t think we can exclude an IP adress at the result page level. Is that right? I'm sure other large advertisers may have experienced this problem. HELP!
