For a millennial, full-time digital marketing professional who runs ad campaigns for the tech startup she’s employed for, learning AdWords seems quite feasible.
For an electrician, roofer, locksmith, or contractor, PPC can be more of a challenge. They may not have grown up with the internet, and they certainly did not attend school to become digital advertisers. They more likely attended a trade school to master the jobs they do now. Their priorities are fixing your pipes, repairing your roofs, and ensuring your televisions are installed properly.
