I am wondering which ad will show in the state where the regional ads are set to run. The regional campaign ads or the national ones or both? I have a higher bid on the national campaign.
This was their response: If the same keyword is contained in both your regionally-targeted campaigns and global or nationally-targeted campaigns, the highest ranking ad (with the higher maximum CPC setting) will appear. Ad ranking varies per keyword and is determined by a combination of your maximum cost-per-click (CPC) and your clickthrough rate (CTR) in relation to other advertisers' CPCs and CTRs. Therefore, as you and other advertisers change CPCs and CTRs, the positions of our ads will also change.
