It's the vertical that's the problem now. Adwords has been clamping down heavily on home services and travel (flight bookings) over the last 6 months.
There have been a lot of scams being run out of India for flight bookings where someone books a flight, the agent deliberately makes a mistake (wrong date/flight/name) and then charges an extortionate fee to amend the booking. The agent has a grace period to make changes so it doesn't cost them anything with the airline, but they still charge the customer.
With travel, they are checking that the business is genuine (i.e. has a physical building, is registered as a travel agent etc., making dummy calls to see where the calls end up etc.). I know a number of agencies that won't touch travel anymore because of account suspensions.
With the introduction of the Google Guaranteed Local Services in the US, affiliates will struggle to run home services PPCall ads.
