Case Study — First 21 Days
We paid $3.15 a click while Google charged us $35.
Same commercial jobs. A fraction of the cost. Every number on this page is honest — what closed, what didn't, and what it actually took to get here.
Cost per click, head to head
Same commercial intentA commercial lead runs us $125–$150 on Google. On ChatGPT, our cost per lead was $20.40.
Why we tested this
If you run a service business, you've probably been burned by a marketing company before. Big promises, a slick dashboard, a retainer that disappears every month — and leads that never quite show up. We have too. We don't blame you for being skeptical; you should be.
We're a door company first. The Door Fixer is our own shop here in DFW, and we're not interested in theories. We wanted to know if a new ad channel could actually put commercial jobs on our calendar for less than we pay everywhere else.
So we ran a small, controlled test on a channel almost nobody in the trades is using yet: ads inside ChatGPT.
The numbers, all of them
21 days. One controlled budget. Here's exactly what it produced.
Still open: 10 of the 25 leads are active jobs we haven't closed yet — so the $7,420 is what's already booked, not a projection.
What actually happened
- First leads landed within days of going live — not weeks.
- 25 total leads came in at a $20.40 average cost per lead.
- 5 jobs closed so far, averaging about $1,484 in revenue each.
- 10 more leads are still active in our pipeline right now.
A commercial builder reached out who needed metal frames installed across a large shop. Real scope, real timeline, a job we were glad to take.
From a single lead that cost us about twenty dollars to acquire.
Why the leads are this cheap — and why that won't last
Almost no one is bidding yet
There's no auction war inside ChatGPT for trade keywords. While everyone else fights over expensive Google clicks, this space is wide open — so prices haven't been driven up.
Higher intent than scrolling a feed
People asking ChatGPT for help are mid-decision, describing a real problem in their own words. That's a warmer starting point than someone half-watching ads between videos.
Cheap channels don't stay cheap
Every low-cost channel gets crowded eventually, and costs climb as more businesses pile in. The cheap clicks are an early-mover window — not a permanent rate.
Should you test ChatGPT ads?
Maybe. Maybe not — it depends on your market, your margins, and the jobs you actually want. That's the whole point of a consultation: an honest look at whether this fits your business, not a pitch with a contract attached.
No retainer, no pressure, no obligation. If it's not a fit, we'll tell you.
Want the full breakdown first?
No call required. We'll email you the complete case study — spend, leads, closes, and the open pipeline — so you can judge the numbers yourself.
No spam, no retainer pitch. Just the numbers, once.
