I work at an ad agency in Texas. We have a customer who is a franchise who decided for one location the parent location (A) to use a different agency while we still maintain Ads for the other location (B). The question I have is if we set up a new Ads account for B targeting a different geographical area but the Ads point to the same domain for A will this flag as double dipping or unfair advantage?

The only other 2 solutions I have is having B send ad spend money to A but we manage that campaign in the shared or let B go to the other agency. They do not want to create a new domain as they are franchises with other locations and want the name recognition.

Any help would be greatly appreciated.
