How to Find Wasted Spend in Google Ads

The average Google Ads account wastes 25–30% of its budget. Here’s where that money usually leaks.

1. The search-terms report

Shows what people actually typed. Irrelevant terms = wasted spend. Add them as negative keywords.

2. Loose location targeting

Default settings often target far beyond your service area. Tighten it.

3. Broad match without negatives

Powerful — or a budget sink without a strong negative list.

4. Fake conversions

If page views count as conversions, Google optimises toward cheap, useless clicks. (Here’s how that happens.)
