They customised every ad headline based on the location of their product.
Eg: "Buy Red Widget New York", "Buy Red Widget Boston", etc
However, the adgroup also has a default ad with headline: "Buy Widgets"
Q - Bearing in mind that ads are shown based on cost & CTR, what defines which ad appears?
Is it the ad sent on the spreadsheet to Google & posted by them,
OR, is it the Default ad?
Having done a few tests, we're not sure. It seems to be a mixture which should not be the case. ie only ads uploaded by Google on the spreadsheet should be appearing - not the default ad - Assume same CPC.
CTR should not be relevant here as we don't (typically) want the default ad to show.
We dropped the default ad temporarily, and only the ads uploaded via spreadsheet were shown but when the default ad was enabled again, it started showing up again.
We think this is a bug but are happy to be proved wrong!
Anyone care to comment?
TIA
