In Google Ads, you pay for clicks, not customers.
If your targeting is too broad, you're paying for:
People searching "free project management software" when you sell a $500/year enterprise tool
"DIY leather wallet tutorial" when you sell premium wallets
"Best cheap alternatives to [your product]" when you're the premium option
The worst part? You don't see this in standard reports.
Google Ads shows you: Campaign A — 1,000 clicks, $2,500 spend, 45 conversions, 5x ROAS. Looks great.
But drill down into the search terms:
700 clicks from high-intent searches → 45 conversions
300 clicks from "free," "cheap," "diy" searches → 0 conversions
That's $750 wasted hiding inside a "winning" campaign.
The Search Hygiene Cockpit is your surgical cleanup tool. It finds those 300 garbage clicks, shows you exactly what people searched for, and gives you a one-click button to block them forever.
