Welcome to WebmasterWorld Guest from 22.214.171.124
When we have this Url as Showing-URL (not the aim Url!) in the adgroup, constantly utopian Minumum-CPCs are here demanded. If we take for a test an another domain as showing Url (not aim URL), we donīt have these utopian CPCs demands.
Unfortunately, the support team is very uncooperative.
Knows somebody, because of which factors a domain can be devalued so and what we can do against this?
If I make it right I think what Armi means is he/she has tried using two different domains as the display URL for the same ads but Google asks for different min CPCs.
For that you'd better still contact Adwords support. I personally haven't experienced that problem and I can't think of any proper explanation.
