i'm setting up a campaign where i only want specific geographic searches. so i only want searches such as "widgets London" or "widgets brighton". on bigger towns it accepts my ad, but on smaller more obscure towns it doesn't telling me it is "low search volume".
my question is when i search on google for one of the more obscure ones that google regected from me it shows other peoples ads. how can i get my ads shown on searches that google says are "low search volume"?
