The situation

LumiAir does specialised cleaning: air scrubbing, disinfection, mould. Every conversion from Google Ads was costing over $90, and the account was paying for searches that had nothing to do with the work.

What we built

  • Keywords cut back to the ones that produced jobs
  • Negative keyword list rebuilt, so the budget stopped going to irrelevant searches
  • Ad variations tested against each other every month
  • Bidding reworked around the searches that converted
