Has anyone else had continuous trouble with AdWords displaying the wrong ads for PPC campaigns? I have several campaigns that display ads from other, unrelated campaigns in my AdWords account. I have checked all of the usual suspects, and there is no rhyme or reason other than a technical mistake on the part of Google. I have had no success in getting Google to admit that they are at fault, even when I know they are. I am tired of the run around from their Technical team and I am looking for any input from other PPC advertisers?
If you are hoping that the Adsense will pick up "what to sell" on your main text, it does not always work.
If you have Adsense tagged key areas (section targeting, see https://www.google.com/adsense/support/bin/answer.py?hl=en&answer=23168 ) and that does not help, you are probably a victim of the new "Interest Based" ad system. Go into the Adsense account and check that the site is not marked to "Display Interest Based Ads".
