I am not an agency. I am a customer who uses an agency.
Facebook and Google are the enemy. They do everything humanly possible to get you to overspend and broaden the search to unnecessary things to trick you to make an unnecessary spend.
Google software constantly has pop ups to try to get you to broaden search filters after we intentionally limited them.
Google’s salesmen (excuse me “consultants”) would constantly call to try to trick the customer into increasing spend, until I stopped taking their calls.
Google has a history of trying to hide data in order to stop the client from organizing effective targeting and this forcing the client to overspend. They got rid of Average Position, then they got rid of search term reports.
Only a fool does not use an independent PPC consultant.
