Free Google Ads Audit: What You Can Check Yourself in 20 Minutes (and When to Call a Pro)

You can run a useful free Google Ads audit yourself in about 20 minutes by checking three things: what people actually typed before clicking, whether your phone calls are being counted, and where your ads are aimed. A professional review is worth considering when those checks turn up problems you can't explain, or when you'd rather be on a roof than in a dashboard.

Here's the map. Three questions, roughly seven minutes each. No marketing degree required.

Picture this: the click that was never going to call

Picture a plumbing owner. Call him Dave. He's not real, but his Tuesday might feel familiar.

Dave bids on "water heater repair." Sounds right. He opens his account for the first time in a month and clicks into a report he's never touched. There it is: someone typed "how to relight a water heater pilot myself," saw his ad, clicked, watched nothing, and left. Below it, a search for a water heater job listing. Below that, someone in a town he doesn't serve.

Dave's not bad at business. He's just been paying for clicks without ever seeing the actual searches behind them. Whatever those clicks cost him, each one had close to zero chance of becoming a job. That's the whole audit in one scene. You're looking for the gap between what you think you're paying for and what you're actually paying for.

Before you start: what a self-audit can and can't do

Let's be honest about the limits. A 20-minute check finds leaks. It doesn't tell you whether your account is great, and it can't replace someone who builds campaigns for a living. Think of it like checking your tire pressure. Useful, quick, and not a substitute for a mechanic.

Also, some free audit offers may include a sales conversation. That's not automatically bad, but know what you're walking into. More on that below.

Grab your login, a coffee and a timer.

Check 1: Who are you actually paying to reach? (7 minutes)

Two terms first, because they sound alike and mean different things:

• Keywords are what you bid on.
• Search terms are what people actually typed.

The search terms report shows the real queries that triggered your ads. Open it and scan the list with one question: would I send a truck for this person?

Look for three kinds of junk:

1. DIY searchers. People who want to fix it themselves.
2. Job seekers and students. People looking for work or for training, not service.
3. Services you don't offer. You do air conditioning; they want a refrigerator repaired.

If you find junk, the fix is negative keywords, which are words you tell Google to skip. Two things worth knowing, straight from Google's help page:

• Negative keywords come in broad, phrase and exact match types, and they work differently from regular keywords. A negative broad match blocks the ad only if the search contains all of your negative terms, in any order.
• Negatives don't match close variants or synonyms. Block one wording and a close variation or a synonym can still trigger your ad. And piling on too many negatives can shrink your reach.

So this isn't a "block everything scary" exercise. It's a trim, not a chainsaw.

What this check tells you: whether your budget is chasing customers or curiosity. What it doesn't tell you: which of the good searches are worth more than others. That takes context on your jobs and margins.

Check 2: Are you counting the calls that pay the bills? (7 minutes)

If your customers call rather than fill out a form, Google needs to count those calls. If it isn't counting them, the account can look like it produces nothing, or it can make decisions off the wrong signals.

Go to your conversion settings and ask:

• Is call tracking set up at all? Google's call reporting counts calls to a Google forwarding number, from a call button or from manual dialing.
• How long does a call have to be to count? A phone call conversion is defined by call duration, and you set that. A five-second wrong number shouldn't be scored like a booked job.
• Is the form on your website tracked too? Conversions can include website actions as well as calls.

Now a wrinkle. Manually dialed calls count at the campaign and ad group level, but not for individual keywords and ads. So if you're trying to figure out which exact keyword produced a phone call, the data may be thinner than you'd hope. Also, calls are reported on the date they happen, while call conversions are reported on the date of the ad click. If your numbers look off by a day or two, that timing difference can be one reason.

Google's help pages on conversion tracking also have some older details about how calls from mobile versus computers are counted. Check the current behavior in your own account before you lean on any one number.

What this check tells you: whether your dashboard reflects reality. What it doesn't tell you: whether your office actually answers the phone. That's a separate audit, and it's a big one. The best ad in the world dies on voicemail.

Check 3: Is the money aimed at your real service area? (6 minutes)

Last one. Open your campaign settings (menu names can change, so if you can't find something, Google Ads Help can point you to it) and look at three items:

1. Location. Does the targeting match where your trucks actually go? A radius that made sense when you started may not match today's routes.
2. Schedule. Are ads running at times when nobody can pick up? Or when you'd rather they run, like emergencies?
3. Budget versus campaigns. Is one campaign eating most of the money while the service you want more of gets scraps?

Then do one small reality test. Pull up your own ad on your phone the way a customer would. Does the ad say what you do, where you do it and how to reach you? Does the page it lands on say the same thing? If a stranger would be confused, so is your customer, and confused customers don't call.

The turn: the problem can be more than one thing

It's tempting to expect the audit to find one dramatic villain. A keyword. A setting. A rogue button.

But think about how the three checks interact. Junk searches can inflate your spend. Uncounted calls can hide which searches were good. And loose location settings can let both problems grow. Fix one and you can still be misled by the other two.

That's why the order matters. Search terms first, so you know who's clicking. Conversions second, so you can tell what's working. Settings third, so you can aim the spend. Skip ahead and you're steering with a broken speedometer.

What this means for your wallet

Costs in Google Ads vary. They depend on your trade, your city, how much competition you have, how your ads and pages perform, and how your account is set up. So we won't hand you a number. What we can say is that every click you pay for that has zero chance of becoming a job is money you could have spent on one that does.

Your 20 minutes doesn't guarantee more leads. It shows you whether you might be leaking, and roughly where.

When a professional review is worth it

Do the self-audit first. Then consider a pro review if any of these are true:

• You found problems and don't know the fix. Or you fixed them and the picture still looks murky.
• You can't trust your tracking. If you're not sure calls are counted properly, every other number is shaky.
• Your time is worth more than the dashboard. If you'd have to learn the platform to keep it healthy, that's a real cost too.

When you ask for a review, ask three questions: What exactly will you look at? Will I get the findings even if I don't hire you? Who is actually doing the work afterward? A good answer is specific. A vague answer is a pitch.

Prior client work included 30 booked appointments in 30 days for a high-ticket service business. That was past work for that client, not a promise of what your account will do. Every account, market and budget is different.

The takeaway

You don't need a consultant to start finding out whether Google is sending you real customers or just clicks. You need 20 minutes, three questions and a willingness to look at the ugly searches. Do that once, and you'll have a better idea whether you need a tune-up or a new set of hands.

FAQ

Is a free Google Ads audit really free?

The one in this article is, because you run it yourself. Free audits from agencies may cost you a sales conversation. That's fine if you know it going in. Ask what they'll review and whether you keep the findings either way.

How often should I check my search terms report?

There's no magic schedule. Since search terms are what people really typed, new junk can show up any time your campaigns change or the market shifts. A regular check-in, on a rhythm you'll actually stick to, beats a big cleanup once a year.

Can I audit Local Services Ads the same way?

Not exactly. Local Services Ads are set up differently from Search campaigns. Industry guides say they charge per valid lead rather than per click, with a weekly budget you set, but check Google's Local Services help center for the current details. The mindset carries over: know what you pay for, and know whether it turns into booked jobs.
