Optimization
How to Find Wasted Spend in Google Ads
Wasted spend is usually found by reviewing search terms, weak locations, poor device performance, low-intent keywords, and pages that do not convert.
Review search terms
The search terms report often shows the clearest waste. Irrelevant searches, research-heavy phrases, job seekers, competitors, and support queries may need negative keywords.
Check locations
A campaign can spend outside the most valuable area if location settings are too broad. Review performance by location and compare cost, leads, and lead quality.
Compare devices
Mobile and desktop users can behave differently. If one device spends heavily without producing useful conversions, the campaign may need landing page improvements or bid adjustments.
Look beyond the ad account
Sometimes the waste is not caused by keywords or bids. A slow page, unclear offer, broken form, or weak follow-up process can turn paid traffic into poor results.
