The Negative Keyword List Every Contractor Should Start With

Negative keywords tell Google which searches should never trigger your ads. Without them, a plumber bidding on "plumbing" can pay for clicks from people looking for plumbing jobs, plumbing school, or how to fix a toilet themselves. Every one of those clicks costs real money and never becomes a booked job.

Job seekers

  • jobs, hiring, career, careers, employment
  • salary, pay, wage, apprentice, apprenticeship
  • license, licensing, certification, school, training, course

Do it yourself searchers

  • how to, diy, yourself, tutorial, video, youtube
  • parts, part, supply, supplies, store
  • home depot, lowes, amazon

Wrong intent

  • free, cheap (test this one, some markets convert)
  • used, salvage, scrap
  • reviews of products, brand names you do not service
  • manual, diagram, specs

Review your search terms every week

A starter list blocks the obvious waste, but every market is different. Open the Search Terms report in Google Ads once a week, look at what people actually typed, and add anything that would never turn into a job. Most contractors find a few new ones every single week.

The goal is not the most clicks. It is the most calls from homeowners ready to hire, at a cost per lead that makes sense for your jobs.
