Your suspicions are correct. Unfortunately, this type of behave for locksmiths is fairly common. I used to run locksmith campaigns across the US and it’s pretty “territorial” Whenever you enter a new market the owner of the chain often will ask their techs to search on google and click your ads. What is challenging here is they are all traveling around the city and are remote. What they are trying to do is exhaust daily budgets so you aren’t competing in auction for that day anymore. If you use a click fraud software then what ends up happening is you exclude IP addresses From cellphone towers. It’s like having a “hit” on your ADs. Eventually it will stop so you may need to ride it out.
