30-minute Google Ads audit framework we run across client accounts. Most accounts have 10-30% wasted spend hiding.
Quick answer
The short version: most teams overcomplicate this. Below is the actual sequence we run for clients, what works, what's a waste of time, and the order to do things in for compounding results.

Most Google Ads accounts hide meaningful wasted spend that a focused audit surfaces fast.
A 30-minute pass in a fixed order captures most of the value of a deep audit.
Search terms, structure, and conversion tracking are where the biggest waste usually lives.
End with a prioritized fix list, not an exhaustive report.
Wasted spend is usually hiding
Most Google Ads accounts carry a meaningful chunk of wasted spend — often a noticeable share of budget — that simply is not visible until someone looks for it. A focused audit surfaces it quickly, because the waste tends to cluster in predictable places. The point of the audit is not to admire the account but to find that waste and the few high-impact problems holding performance back, so you can redirect budget toward what works.
This is why a regular audit pays for itself. Spend leaks back in over time as search terms drift and structure decays, so a periodic focused review keeps the account efficient rather than slowly bleeding budget on traffic that never converts.
Follow a fixed sequence
Audits sprawl when you wander. The fix is a fixed order that covers the high-impact areas without rabbit-holing. Start with the search terms report, where irrelevant queries quietly consume budget — this is usually where the biggest waste hides. Then account structure and budget allocation. Then conversion tracking, confirming it fires accurately, since everything optimizes toward it. Then bidding, creative, and targeting. Moving through these in order surfaces the show-stoppers before the cosmetic issues.
This sequence naturally prioritizes by impact. A broken conversion setup or a flood of wasteful search terms matters far more than a suboptimal ad extension, and the order ensures you find the expensive problems first.
Prioritize fixes over findings
A thorough audit can generate a long list of observations, most of which barely move performance. The skill is separating the few issues that matter — wasted search terms, broken tracking, poor structure, misallocated budget — from minor flags that pad a report. Chasing every small issue keeps you busy without improving results.
End with a short, prioritized action list rather than an exhaustive document. A handful of high-impact fixes you will actually implement beats a comprehensive report that overwhelms and gets shelved. The value of the audit is entirely in what gets changed afterward — usually cutting the wasted spend and fixing the tracking — so optimize the whole exercise for action.
Common mistakes that quietly kill results
These come straight from audits we run every week. If any of them stings, you’re in good company — and the fix is usually faster than you think.
Ignoring landing page speed. A 1-second delay costs roughly 7% of conversions. You're paying for the click either way — make it land on something that loads in under 2.5 seconds.
Changing three things at once. New audience + new creative + new bid strategy = you learn nothing. One meaningful change per campaign per week. Boring, but it's how you build an account you actually understand.
Broad-matching your way to wasted spend. On Google, one unreviewed broad-match keyword can quietly burn 20-30% of budget on garbage queries. Review search terms weekly for the first month of any new campaign, then bi-weekly.
Judging ads on ROAS alone. Platform ROAS over-credits retargeting and under-credits prospecting. Watch new-customer CAC and contribution margin, or you'll keep feeding the campaign that's just harvesting people who'd buy anyway.
From the trenches
A furniture brand was thrilled with a 6.1 blended ROAS — until we split it: retargeting at 14, prospecting at 1.3. We rebuilt prospecting around video hooks from customer reviews. Ninety days later: blended 4.8, but new-customer revenue up 85%. Better business, 'worse' dashboard.

How long should a Google Ads audit take?
About 30 minutes for the issues that matter. The goal is a short, prioritized fix list — usually cutting wasted spend and fixing tracking — not an exhaustive report nobody acts on.
