What a Google Ads audit actually finds: 7 places budget leaks
Most Google Ads accounts waste a meaningful share of spend in the same predictable places. Here's the checklist we run — and the leaks that show up almost every time.
Nearly every Google Ads account we audit is leaking budget in the same handful of places. The good news: these leaks are fixable, and plugging them often lifts performance faster than adding spend. Here's what a real audit looks for.
1. Search terms you never meant to pay for
The single most common leak. Broad and phrase match quietly pull in irrelevant searches — wrong intent, wrong location, job-seekers, competitors, "free" hunters. The fix is a disciplined negative keyword list and a regular search-terms review. Money spent on the wrong query is money gone.
2. Optimising to the wrong conversion
If the account counts every form fill or "any conversion" as success, Google will optimise toward cheap conversions — including junk. Auditing what's actually tracked, and whether it reflects qualified leads or revenue, usually reveals the biggest strategic problem. (More: why your Google Ads clicks don't become customers.)
3. Paying for your own brand
Performance Max and broad campaigns often claim credit for branded searches you'd have won organically for free. Without brand exclusions, your "great ROAS" is partly just harvesting existing demand. An audit separates incremental sales from recycled ones.
4. Landing pages that don't match the ad
You can win the click and still lose the lead if the landing page is slow, off-message, or asks too much. A click that lands on a page built to convert is worth several that land on a homepage. This is where ads and CRO meet.
5. Quality Score you're overpaying for
Low Quality Scores mean you pay more per click for the same position. The audit checks the ad-to-keyword-to-landing-page relevance chain, because raising Quality Score lowers cost without touching budget.
6. Wrong campaign type for the goal
Running everything through one campaign type — or defaulting to Performance Max without guardrails — leaves performance on the table. Different goals need different structures. (See which Google campaign type fits you.)
7. Device, location and schedule blind spots
Accounts often spend evenly across devices, regions and hours that convert very differently. The audit compares performance by segment and reallocates budget toward what actually books enquiries — and away from what doesn't.
What to do with an audit
An audit is only useful if it turns into changes. Ours produces a waste map — what to cut now, what to fix next, and what to rebuild — sequenced by impact, not effort. The pattern is almost always the same: fix tracking, cut waste, match landing pages, then scale what's proven.
