The changes behind the results
The challenge
O’ahu Electric and Air already had campaigns running, but they weren’t generating enough leads at an efficient cost. Brand and service terms were mixed together as well which made it harder to control spending and tailor ads to each search.
The goal was to grow enquiry volume across HVAC installations and repairs, residential electrical work, and commercial electrical services all with a stronger focus on lead quality.
What we changed
Built campaigns around specific services.
We launched new Search and Performance Max campaigns, with service-focused ad groups for air conditioning, residential electrical work, and emergency electrical services. This allowed us to better match ads to what potential customers needed.
Improved the journey from click to enquiry.
We built and optimised landing pages to make services clearer, highlight the companies benefits and help visitors take the next step. Alongside campaign improvements, this helped lift the conversion rate from 3.55% to 10.05%.
Refined traffic and scaled what performed.
We continually added negative keywords to filter out irrelevant searches and adjusted budgets based on performance, directing more spend towards campaigns delivering results. We also increased budgets based on performance, growing enquiry volume while bringing cost per conversion down from US$12.61 to US$7.21. This allowed us to scale campaigns successfully while improving efficiency.
The results
Monthly form submissions grew from an average of 7 to 20, and phone calls tripled. At the same time, cost per conversion fell by 43% meaning the account generated more tracked conversions for each dollar spent.
Search impression share also increased from 28.55% to 34.27%, giving O’ahu Electric and Air greater visibility in the searches it was eligible to appear in.
Results reflect reported performance changes during February–July 2026.
