Somewhere in your Google Ads account, money is leaking. Not maybe. Almost certainly.
That’s not a scare tactic, it’s just the math. A massive WordStream study that ran more than 15,000 accounts through its grader found the average Google Ads account wastes about $1,127 every month, which works out to roughly $3,383 over a 90-day window. And since that same dataset put the median account’s spend at around $3,127 a month, the waste represents more than a third of a typical budget going to clicks that produce nothing. Even more startling: nearly 29% of accounts recorded zero conversions over a 90-day period. One in four advertisers, paying for clicks, getting nothing measurable back.
The good news? Most of that waste is findable, and a proper audit finds it. Here’s the checklist a real one runs through.
Why most audits miss the money leaks
First, a warning about audits themselves, because not all of them are worth the PDF they’re printed on.
A lot of “free audits” are sales theater. They run an automated tool, spit out a generic report full of yellow warning icons, and conclude, shockingly, that you need their help. They check surface metrics and ignore the plumbing underneath, which is exactly where the expensive problems hide. A real audit goes deeper than “your click-through rate is below average.” It traces the money. It asks where every dollar goes and whether each one has a job.
The twelve items below are the ones that actually move the needle. Work through them honestly and you’ll find your leaks.
The 12-point Google Ads audit checklist
- Conversion tracking. Start here, always. Verify that every conversion action is firing correctly, counting real outcomes, and not double-counting. How to spot trouble: run a test conversion and watch whether it registers, and check for duplicate tags or goals firing on page load instead of actual submission. If tracking is broken, every other number in the account is fiction, and the algorithm is optimizing toward a lie.
- Search terms report. This is where you see what people actually typed to trigger your ads, as opposed to the keywords you bid on. Why it matters: thanks to broad match, the gap between the two can be enormous. How to spot the problem: sort by spend and look for irrelevant queries eating budget. In healthy accounts, very little goes to junk searches; in neglected ones, a painful share does.
- Negative keywords. The flip side of the search terms report. Check whether you have a real, maintained negative keyword list, or just a token few. Why it matters: negatives are how you stop paying for the junk you found in item two. How to spot the problem: a thin or empty negative list on an account running broad or phrase match is a guaranteed leak.
- Match types. Look at how much of your spend rides on broad match without tight controls. Why it matters: broad match casts a wide net, and without strong negatives and good signals, it drifts toward low-intent traffic. How to spot the problem: heavy broad-match spend paired with a weak search terms report is a classic waste pattern.
- Campaign structure. Is the account organized logically, with tight themes, or is it a tangle of overlapping campaigns and bloated ad groups? Why it matters: messy structure makes optimization nearly impossible and dilutes relevance. How to spot the problem: ad groups crammed with dozens of unrelated keywords are a tell.
- Geographic targeting. Confirm you’re targeting the right locations, and the right kind of targeting. Why it matters: the wrong setting can serve your ads to people merely “interested in” your area rather than actually in it, including clicks from other countries. How to spot the problem: open the locations report, sort by cost, and look for spend outside the places you actually serve.
- Ad scheduling. Check when your ads run versus when you can actually convert. Why it matters: paying for clicks at 3 a.m. when nobody answers the phone is money down the drain for many lead-gen businesses. How to spot the problem: conversions clustering in certain hours while spend spreads evenly across all of them.
- Device performance. Break performance down by device. Why it matters: an account can convert beautifully on desktop and abysmally on mobile, often because the mobile experience is broken. How to spot the problem: a big gap in conversion rate between devices, with budget still flowing to the weak one.
- Landing page alignment. Look at where your ads send people and whether the page matches the ad’s promise. Why it matters: a great ad pointing at a slow, off-message, or generic page wastes the click you paid for. How to spot the problem: ads driving to the homepage instead of a dedicated, relevant page is a common and costly miss.
- Quality Score. Review Quality Scores across your key keywords. Why it matters: low scores mean you pay more per click for worse positions, a compounding tax on the whole account. How to spot the problem: scores below 5 on important keywords flag relevance or landing-page problems worth fixing.
- Bidding strategy. Examine whether your bid strategy fits your goals and whether it has enough conversion data to work. Why it matters: smart bidding starved of clean conversion data, or set to an unrealistic target, throttles your best campaigns. How to spot the problem: a target CPA set far below your actual average, choking volume.
- Wasted spend overall. Finally, zoom out. Add up the spend on zero-converting keywords, irrelevant searches, and underperforming segments. Why it matters: this is the bottom-line number that tells you how much budget you could reclaim. How to spot the problem: it’s the sum of everything above, and it’s usually bigger than anyone expects.
That’s the Google Ads audit checklist in full. Twelve items, each one a place money commonly hides.
How to score your account
Reading the list is one thing; turning it into a decision is another. Here’s a simple way to score.
Go through the twelve items and mark each one green, yellow, or red. Green means it’s solid. Yellow means it needs attention. Red means it’s actively costing you money right now. Be ruthless; grading on a curve here only fools yourself.
Then count the reds. Zero to two reds, and you’ve got a healthy account that needs tuning, not surgery. Three to five reds, and you’ve got real leaks worth fixing soon, in priority order, biggest first. Six or more reds, and you’re not looking at a tune-up anymore. You’re looking at a rebuild, which brings us to the uncomfortable question most audits dodge.
When the answer is “rebuild,” not “tweak”
Sometimes an account is too far gone to optimize, and the honest move is to start fresh.
This feels wasteful, like throwing away work. But pouring optimization into a fundamentally broken account is the actual waste. If the structure is a mess, the tracking is unreliable, the history is polluted with bad data the algorithm has learned from, and half the checklist is red, tweaking around the edges just delays the inevitable. A clean rebuild, proper structure, correct tracking, tight match types, fresh campaigns, often outperforms months of patching within weeks.
How do you know which camp you’re in? Roughly: if your bones are good and the problems are fixable in place, optimize. If the foundation itself is rotten, rebuild. A good auditor will tell you the truth here even when “rebuild” is the harder sell, because recommending endless tweaks on a doomed account is how agencies keep billing without fixing anything.
The takeaway? An audit isn’t a formality or a sales gimmick. Done right, it’s a treasure map to money you’re already spending but not capturing. The twelve points above are where the treasure tends to be buried.
How often should you actually audit?
A full twelve-point audit isn’t a once-and-forget thing, but it’s also not something you do every week. The right rhythm depends on how much you spend and how fast your account moves.
For most accounts, a thorough audit once a quarter strikes the right balance. Enough time passes for patterns to emerge, but not so much that a leak runs for half a year before anyone notices. Between those deep audits, a lighter monthly check on the high-risk items, conversion tracking, the search terms report, and wasted spend, catches the fast-moving problems before they compound. New irrelevant search queries appear constantly as Google reinterprets broad match keywords in creative ways, so the search terms report in particular rewards frequent attention.
Higher-spend accounts deserve more frequent eyes, simply because the dollar cost of any given leak is bigger. If you’re spending $50,000 a month, a problem that wastes 10% of budget is $5,000 walking out the door, and waiting three months to catch it is expensive patience. Scale the cadence to the stakes.
And one underrated trigger: audit after any major change. A site redesign, a new tracking setup, a campaign overhaul, a switch in bidding strategy. These are exactly the moments tracking quietly breaks or structure drifts, and catching it immediately beats discovering it a quarter later in a report.
What a good audit report should look like
Since we’re on the subject of audits, it’s worth knowing what separates a useful report from a sales prop.
A real audit report quantifies the problem. It doesn’t just say “your negative keywords need work,” it tells you roughly how much that gap is costing you and what reclaiming it would look like. Numbers, not adjectives. It also prioritizes, because not every issue is equally urgent, and a report that flags forty problems with no sense of which three matter most is just noise dressed up as thoroughness.
It should be specific to your account, too. If the findings could apply to literally any advertiser, an automated tool generated them and nobody actually looked. The valuable insights are the ones that reference your campaigns, your search terms, your structure by name. And it should end with a clear recommendation: tune up, fix these specific things, or rebuild, stated plainly rather than buried under a pile of vague “opportunities.”
If a report doesn’t do those things, it’s not an audit. It’s a brochure with a chart on it.
Who put this together
This checklist comes straight out of the audits Digital Drew SEM runs on accounts every week. Drew Blumenthal founded the agency after years managing digital marketing for Fortune 500 companies and leading agencies, and he’s the one in the accounts personally, tracing where the money goes rather than handing clients a vanity report. The agency is a Google Premier Partner and a Semrush Certified Partner, which in plain terms means the audits have to actually find and fix real waste, not just generate yellow warning icons.
The difference between an audit that helps and one that wastes your time usually comes down to whether the person running it cares more about your results or their next invoice.
Run it yourself, or have it run for you
A couple of ways forward:
- Want the full thing as a working document? Grab the downloadable version and more from the checklists library and run your own audit at your own pace.
- If the account needs more than a checklist, Google Ads management is where the fixing and, when needed, the rebuilding happen.
- Or book a call and have this exact 12-point audit run on your account for free. You’ll get a straight answer on what’s leaking, what it’s costing you, and whether you’re a tune-up or a rebuild, with no obligation to do anything about it.
Every account tells a story in its numbers. The only question is whether anyone’s bothered to read yours closely. Most of that wasted $1,127 a month is sitting there waiting to be found.
Frequently Asked Questions
What should a Google Ads audit include?
A real audit checks the plumbing, not just surface metrics. At minimum, it should cover conversion tracking, the search terms report, negative keywords, match types, campaign structure, geographic targeting, ad scheduling, device performance, landing page alignment, Quality Score, bidding strategy, and total wasted spend. Each item is a place where money commonly hides.
How much money does the average Google Ads account waste?
A study of more than 15,000 accounts found the average account wastes roughly $1,127 a month, which is over a third of a typical budget. Even more striking, nearly 29% of accounts recorded zero conversions over 90 days. Most of that waste is findable, which is exactly what a proper audit is for.
How often should I audit my Google Ads account?
A thorough audit once a quarter works for most accounts, with lighter monthly checks on the high-risk items like conversion tracking, the search terms report, and wasted spend. Higher-spend accounts deserve more frequent attention, and you should always audit after a major change like a site redesign, a new tracking setup, or a campaign overhaul.
When should I rebuild my Google Ads account instead of optimizing it?
Rebuild when the foundation itself is broken, meaning the structure is a mess, tracking is unreliable, the history is polluted with bad data, and most of the checklist is red. Optimizing a fundamentally broken account just delays the inevitable. If the bones are good and the problems are fixable in place, optimize; if the foundation is rotten, a clean rebuild often outperforms months of patching.
