What $1.33M+ in Google Ads taught me about where the money goes.

1. One dollar in five was wasted

I audited every search term we paid for from January 2024 to July 2026. $74,278, about 21% of the spend we could see, went to searches that were never going to become a customer. The biggest bucket, $40,665, was people asking "how do I get my keys out of my car" so they could do it themselves.

Wasted spend by type, in dollars. Buckets overlap, so they add up to more than the $74,278 total.

2. Google's automation spent most of it

97.5% of the waste came in through Google's own matching: broad match, "close variants" of phrase and exact keywords, and AI Max. Keywords I typed exactly as written wasted only $477. Automation isn't evil, but left alone it spends your money on searches you'd never choose.

3. If tracking is wrong, bidding is wrong

For a long time our account was optimizing for people who started a form, not people who paid. When I rebuilt tracking, I found 14 conflicting conversion goals (cleaned up to 2) and that about 52% of web-form "leads" were automated test submissions. Google's bidding learns from whatever you tell it is a win. Tell it the truth.

4. Send real revenue back

Now every ad click is tied to the job it became, and the real revenue goes back to Google. Bidding chases paying customers instead of clicks. It's the single change I'd make first in any account.

5. Fake clicks are real money

We paid a monthly subscription just to block fake and repeat clicks. I replaced it with software I built, which watches every click and blocks repeat offenders automatically.

What I'd tell any owner

Pull your search terms report and read it like a bank statement. Build your negative keyword lists before you raise budgets. Don't trust a "conversion" you can't tie to a paying customer. And never let anyone, me included, run your account without showing you those numbers every month.
