Both campaigns are EXACTLY the same, same keywords, same PPC costs, etc - Exact.
The only difference is that the display ads are totally different as are the display URL and the Destination URL and the daily budget is different.
siteA.com is a campaign that has been running since 12/04
siteB.com is a campaign that is new.
When I start the campaign for siteB.com you no longer see the ads for siteA.com.
They should not be competing with each other as destination URLs and display URLs are totally different.
Any ideas?
