How to Do a Google Ads Audit: A Step-by-Step Checklist

So you’ve been running Google Ads for a while, the spend keeps going out the door every month, and lately you’ve had this quiet little feeling in your stomach that some of that money isn’t coming back. First of all, breathe. That feeling is actually a good sign, because it means you’re paying attention. Learning how to do a Google Ads audit is exactly how you turn that worry into clarity.

A Google Ads audit is a structured, top-to-bottom review of your account where you check that conversion tracking is accurate first, then work through your account structure, search terms, keywords and match types, ad copy and assets, Quality Score signals, bidding, budgets, landing pages, and audiences to find where money is leaking and where performance is being left on the table. You don’t guess. You follow a checklist, you look at your own account’s real numbers, and you make a short list of fixes. That’s the whole idea, and I promise it’s more doable than it sounds.

Grab a coffee and a notebook, because we’re going to walk this whole thing together, one calm step at a time. By the end you’ll have a repeatable checklist you can run every quarter without dreading it. Let’s get into it.

How to do a Google Ads audit: what it really is

Let’s start soft, because the word “audit” makes everyone tense up like they’re about to get in trouble with the tax office. It’s not that. An audit is simply you sitting down and asking, honestly, “Is this account doing what I want it to do, and if not, where’s the disconnect?”

Think of it like a health checkup for your account. A good doctor doesn’t just glance at you and guess — they run through the same set of vitals every time, in a sensible order, so nothing important gets missed. That’s exactly what we’re building here: a set of vitals for your Google Ads account that you check in a deliberate sequence. The sequence matters more than people realize, and it’s the first thing most rushed audits get backwards.

Here’s the mindset I want you to hold the whole way through. You are not looking for a magic number or a single villain. You’re looking for gaps — places where your money and your intentions have quietly drifted apart. A keyword that made sense a year ago but doesn’t now. A conversion action that stopped firing after a website update and nobody noticed. A budget pouring into a campaign that was only ever meant to be a small test. These gaps are normal. Every account grows them over time, the way a garden grows weeds. The audit is just how you find them before they take over the bed.

And one more reassurance before we roll up our sleeves: you do not need to be a data scientist to do this well. You need patience, a checklist, and a willingness to look at things you might have been avoiding. That’s it. If you can make a to-do list, you can audit a Google Ads account.

How to do a Google Ads audit: where do you start?

Right here, and this is the single most important thing I’ll tell you in this whole piece, so let me say it plainly: you start every Google Ads audit by verifying that your conversion tracking is accurate. Not budgets, not keywords, not the shiny ad copy. Tracking. First. Always.

Here’s why I’m so firm about this. Every decision Google’s system makes — and every decision you make when you look at the account — leans on the conversion data. If that data is wrong, you’re not optimizing, you’re just confidently walking in the wrong direction. I’ve watched people spend weeks “improving” an account whose tracking had been silently broken the whole time. They were polishing numbers that meant nothing. It’s heartbreaking, and it’s completely avoidable.

So, gently, go check these things in your own account:

• Do your conversion actions actually reflect what you care about? Open your conversions and read them like a stranger would. Is a real lead or sale being counted, or is something loose like “clicked a button” being treated as a win? Make sure the conversions you’re optimizing toward are the ones tied to real business value.
• Are conversions firing recently and consistently? Look at the “last conversion” dates and recent volume. A conversion action that hasn’t recorded anything in a suspiciously long time is a red flag worth chasing down.
• Is anything being double-counted? If one lead is somehow counting as two or three conversions, your cost-per-conversion looks rosy and false. Check whether your count setting matches your goal — leads usually want one count per interaction, sales might want every purchase.
• Did a recent website change break anything? New site, new theme, new checkout, new consent banner — any of these can knock a tag loose. If your tracking predates a big site change, verify it survived.

If any of this feels shaky, that’s your very first fix, full stop. It’s such an important foundation that it deserves its own deep walkthrough — our guide on how to set up conversion tracking in Google Ads takes you through getting it right from scratch. Do not skip past this to the “fun” parts of the audit. I know the keywords are more exciting. Trust me and fix the foundation first, and everything you do afterward will actually mean something.

How do you audit your account structure?

Okay, tracking’s solid — now we can look at the bones of the account. Structure is one of those things that sounds boring but quietly controls everything, like the studs behind a wall. When it’s good, you barely think about it. When it’s messy, every other problem gets harder to see and harder to fix.

Here’s what a healthy structure tends to look like, and what to check for in yours. You want your campaigns organized around clear themes or goals, not thrown together randomly. Each campaign should have a job you can say out loud in one sentence — “this one drives demo bookings for the enterprise product,” for example. If you open a campaign and can’t explain its purpose simply, that’s a gap worth noting.

Then look inside at your ad groups. The gentle rule here is tight themes. Each ad group should hold a small, closely related set of keywords that all share the same intent, so the ads inside can speak directly to that intent. When an ad group becomes a junk drawer of loosely related keywords, your ads can’t be specific to any of them, and relevance suffers across the board. If you find sprawling ad groups stuffed with wildly different search terms, jot down “tighten this” and move on.

A few more structural things to eyeball in your own account:

• Duplicate keywords competing with each other. The same keyword sitting in multiple ad groups or campaigns means your own account is bidding against itself. Note where this is happening.
• Campaign settings that don’t match intent. Check that Search and Display aren’t quietly bundled together in one campaign, since they behave completely differently and lumping them hides where results actually come from.
• Geographic and language targeting that still makes sense. Businesses change. Make sure you’re not still paying to show ads in a region you stopped serving, or in a language your landing pages don’t even speak.
• Naming that a future-you can understand. This one’s small but kind to yourself. Clear names make every future audit faster.

If you’re realizing the structure needs more than a tidy-up, it can be worth revisiting the fundamentals of how a campaign should be built in the first place. Our walkthrough on how to set up a Google Ads campaign lays out the structure the right way from the ground up, and it’s a lovely refresher even for seasoned accounts.

What does the search terms report reveal?

Oh, I love this part. If conversion tracking is the foundation, the search terms report is the confession booth. It shows you the actual phrases people typed before your ad appeared — not the keywords you chose, but the real, messy, human things they searched. And friend, this is where the truth lives.

Here’s the thing nobody tells you clearly: your keywords are not the same as the searches you’re paying for. Especially with broader match types, Google can match your keyword to searches you never imagined, some brilliant and some wildly off-base. The search terms report is how you see the difference between what you intended and what you’re actually buying.

To audit it, open your search terms report and read through it slowly, like you’re reading someone’s diary. For each term, ask one calm question: “Would I happily pay for this click?” You’ll quickly sort them into a few piles:

• Great matches — searches that fit your offer beautifully and are converting. Note any strong ones that aren’t yet their own keyword; they might deserve to be promoted.
• Irrelevant matches — searches that clearly don’t fit. Someone looking for a free version, a job, a competitor, or something adjacent but wrong. These are quietly draining your budget.
• Ambiguous matches — ones you’re unsure about. Set these aside to watch rather than acting hastily.

That middle pile — the irrelevant matches — is your negative keyword goldmine. Every clearly-wrong search you spot is a chance to add a negative keyword so you stop paying for that kind of click going forward. This is honestly one of the highest-value things you’ll do in the whole audit, because it directly stops waste. If negatives are new to you or you want to do them properly rather than haphazardly, our guide on how to use negative keywords in Google Ads walks through building a clean negative strategy without accidentally blocking the good traffic too.

Make this a habit, not a one-time thing. Search behavior shifts constantly, new irrelevant terms sneak in, and a search terms review every couple of weeks keeps the leaks sealed. During the audit, though, just do one thorough pass and build your negative list from what you find.

How do you review keywords and match types?

Now let’s look at the keywords themselves, and the match types that decide how loosely or tightly they trigger. This is where a lot of quiet inefficiency hides, so let’s shine a light on it together.

Start by pulling up your keywords sorted by spend. I want you to look, specifically, at your biggest spenders and ask whether each one is earning its keep. A keyword taking a big slice of budget while bringing in little in return isn’t a villain, exactly, but it’s a conversation. Is the intent right? Is the match type too broad? Is the landing page wrong for it? Note it for a closer look.

Then check the flip side: keywords with lots of impressions but very few clicks, or clicks but no conversions. Each pattern tells a little story. Lots of impressions and few clicks can mean the keyword is technically matching but your ad isn’t resonating, or the intent is off. Clicks but no conversions can point at a landing page problem or a mismatch between what people expected and what they found.

Match types deserve their own gentle pass. Here’s a simple way to hold them in your head:

Match type	How broadly it triggers	What to check in your audit
Broad match	Widest reach; Google interprets intent generously	Pair with strong negatives and watch the search terms report closely, or it can wander
Phrase match	Middle ground; the meaning of your phrase must be present	Good balance for many accounts; confirm the searches still fit your intent
Exact match	Tightest; close variants of your specific meaning	Highest control; check you’re not so narrow that you’re missing valuable variations

There’s no universally “right” match type — it depends on your goals, your budget, and how much you want to control versus discover. The audit question isn’t “am I using the correct one,” it’s “does my match-type mix match how much wandering I can afford right now?” A tight budget usually wants more control; a bigger budget with strong negatives can afford more exploration. Look at your own mix through that lens and note anything that feels out of step with your situation.

Are your ads and assets actually pulling their weight?

Let’s talk about the part your audience actually sees. You can have perfect structure and clean tracking, but if your ads don’t make someone want to click, none of it matters. This is where a little creativity meets the checklist.

Go through your ads and check the honest basics first. Does every ad group have enough ads for the system to test and rotate? A single lonely ad gives Google nothing to optimize between. You generally want a few strong options competing so the best one can rise. If you find ad groups running on one tired ad, that’s a note.

Then read your ads as a customer, not as the person who wrote them. Ask yourself:

• Does the ad speak to the actual search? If someone searched for a specific thing, does your ad reflect that specific thing, or is it generic? Relevance between the search, the keyword, the ad, and the page is the thread that ties good performance together.
• Is there a clear, single reason to click? A benefit, an offer, a reason you’re the right choice. Vague ads get vague results.
• Are your assets complete and useful? Check that your ad extensions and assets — sitelinks, callouts, structured snippets, images where relevant — are actually filled in and current. Empty or outdated assets are free real estate you’re leaving on the table. Confirm the specific asset options available to your campaign type in Google Ads Help, since what’s offered varies by campaign.
• Do the assets point somewhere useful? A sitelink to a page that no longer exists is worse than no sitelink. Click a few and make sure they still land where they should.

For responsive search ads, check the quality of the headlines and descriptions you’ve given the system to work with. It can only remix what you provide, so thin or repetitive inputs cap your results. Variety and genuine relevance in your assets give the system room to find what works.

Don’t try to rewrite everything in one sitting. During the audit, just flag the ad groups with weak or thin creative and the assets that are missing or broken. Fixing them is a separate, calmer task for later.

What do your Quality Score signals tell you?

Quality Score is one of those things people either obsess over or ignore completely, and neither extreme serves you. Let me give you the balanced, honest version.

Quality Score is Google’s diagnostic estimate of how relevant and useful your ads and pages are for a given keyword, and it’s built from a few signals: your expected click-through rate, your ad relevance, and your landing page experience. I want to be careful here — treat it as a diagnostic direction, a hint about where friction lives, not a grade to chase for its own sake. Confirm exactly how it’s defined and displayed in Google Ads Help, since Google is the source of truth on its own metric.

For the audit, pull up Quality Score alongside its component columns (expected CTR, ad relevance, and landing page experience — you can add these as columns). Then read them as clues rather than a report card:

• Low ad relevance? Your ad probably isn’t matching the keyword’s intent closely enough. This often points back to those junk-drawer ad groups we talked about — tighten the theme and the ad can speak more directly.
• Low expected click-through rate? Your ad may not be compelling enough to earn the click, or the keyword intent and ad message are drifting apart.
• Below-average landing page experience? The page people arrive on may be slow, confusing, or not clearly matched to what the ad promised. That’s a landing page fix, which we’ll get to next.

See how nicely those signals map to actions? That’s the gift of Quality Score — not the number itself, but the way its parts point you toward the real friction. Note any keywords where a component is flagged as below average, especially on your higher-spend terms, and let those guide where you dig deeper.

Do your bids and budget match your goals?

Money, rhythm, and intention — this section is where they meet. Let’s make sure your bidding and budgets are actually pointed at what you want, because it’s surprisingly common for them to drift out of alignment.

Start with the big question: what is this campaign actually trying to do, and does its bid strategy match that? A campaign chasing leads at a certain cost, a campaign chasing as many conversions as a budget allows, a campaign protecting a target return — these want different bidding approaches. Open each campaign and check that its strategy genuinely serves its goal. A mismatch here is like driving with the handbrake on: it still moves, but it fights you the whole way.

Then look honestly at whether your automated strategies have what they need. Smart bidding leans heavily on conversion data, which loops us right back to where we started — if tracking is thin or broken, automated bidding is flying blind. This is another reason the tracking check comes first. Confirm the specific bid strategies and their requirements in Google Ads Help so you’re matching each campaign to a strategy it can actually feed.

Now, budgets and pacing. Here’s what to check in your own account:

• Are budget-limited campaigns your best campaigns? If a strong, profitable campaign is capped and running out of budget mid-day, while a weaker one has room to spare, you may be starving your winners. Note where the money could be reallocated toward what’s working.
• Is spend pacing smoothly or lurching? Look at daily spend over time. Wild swings or campaigns that blow through budget early can mean settings need attention.
• Is anything spending with nothing to show? A campaign quietly consuming budget with no conversions over a meaningful period is your loudest red flag. Flag it hard.
• Are seasonal or one-off pushes still running? That holiday campaign you meant to pause in January — go check it’s not still merrily spending in spring.

The goal here isn’t to slash everything. It’s to make sure your money is flowing toward your goals and away from things that aren’t serving them. Gentle reallocation, not panic cutting.

Are your landing pages helping or hurting?

Here’s a truth that stings a little: you can win the entire auction, get the click, pay for it fairly — and then lose everything the moment someone lands on a page that doesn’t deliver. The landing page is where the ad’s promise either comes true or falls apart, and it’s shockingly easy to neglect because it lives on your website, not inside Google Ads.

So click your own ads’ destination pages and experience them as a first-time visitor would. Be honest with yourself. Ask:

• Does the page match the ad’s promise? If your ad talked about a specific product or offer, is that the first thing they see, or do they land on a generic homepage and have to hunt? Message match is everything. A mismatch here quietly wrecks conversion rates.
• Is it fast, especially on a phone? A slow page loses people before they even read it, and mobile is where a huge share of clicks live. Load your pages on your actual phone and feel the wait.
• Is the next step obvious? Can a distracted, busy person tell in two seconds what to do next — buy, book, call, sign up? If the call to action is buried or unclear, you’re leaking conversions you already paid for.
• Does it build a little trust? Clear information, a sense of legitimacy, no broken images or dead links. People decide fast whether to trust a page, and they’re right to be picky.

You don’t need a full redesign to make progress here. Often the highest-value landing page fix in an audit is simply making sure each ad points to the most relevant page you already have, instead of a generic catch-all. Note any ads sending traffic to a weak or mismatched page — that’s a fix with real leverage.

How do you audit audiences and targeting?

We’re in the home stretch, and this section is a lovely one because it’s often where hidden opportunity — not just waste — is waiting. Audiences are how you layer who onto your what, and most accounts under-use them.

In your audit, look at what audience signals and lists you’re using, if any. Check whether you have audiences applied for observation so you can at least see how different groups perform, even where you’re not adjusting bids for them. Confirm the current audience options and how observation versus targeting work in Google Ads Help, since these capabilities evolve. The audit question is simple: am I gathering enough insight about who converts, and am I acting on it?

A few things to check gently in your own account:

• Remarketing coverage. Are you set up to reconnect with people who already visited but didn’t convert? These warm visitors are often some of your most efficient traffic, and missing this is a common gap.
• Audience performance differences. If you’ve had audiences in observation, look for groups that convert notably better or worse. That’s a signal you can lean into or pull back from.
• Location and device patterns. Sometimes the audience story is hiding in your location and device reports. A device or region that consistently under-delivers might deserve an adjustment; one that over-delivers might deserve more love.
• Exclusions. Are you excluding people who’ve already converted where it makes sense, so you’re not paying to re-reach someone who’s already done the thing?

Don’t force complexity you don’t need. For a smaller account, simply turning on observation and remarketing and watching for a while is plenty. The point of this section in your audit is to notice whether you’re leaving audience insight on the table, and to set yourself up to learn more going forward.

How do you find and cut wasted spend?

This is the section everyone secretly comes for, so let’s do it right — and notice that we’ve saved it for last on purpose. You can only see waste clearly after you’ve confirmed your tracking is honest and worked through the rest. Waste-hunting first, before the foundation, is how people cut the wrong things.

Here’s the honest framing I want you to keep, because it’s where a lot of advice goes off the rails: I’m not going to tell you that accounts waste some specific percentage of their budget. Anyone who throws a universal number at you is guessing, and your account isn’t an average — it’s yours. Instead, the method is to look at your own account and find the specific places where money and results have parted ways. Let’s gather them into one list:

• Irrelevant search terms you found earlier — turn them into negatives so you stop paying for those clicks.
• High-spend, low-return keywords — the ones you flagged that take a lot and give little. Decide whether to fix their intent, tighten their match, improve their page, or pause them.
• Redundant or self-competing keywords — duplicates across ad groups that make you bid against yourself.
• Campaigns spending with no conversions over a meaningful window — the loudest leaks, worth investigating before they run any longer.
• Ads pointing to weak or broken pages — you paid for the click and then lost the person.
• Forgotten or seasonal campaigns still quietly running past their purpose.
• Overly broad match without enough negatives — the combination that lets spend wander into searches you never wanted.

Now here’s the part that turns an audit from a worry session into progress: write these as actions, not observations. Not “this keyword spends a lot” but “pause this keyword and move its budget to the campaign that’s capped.” Not “tracking looks off” but “verify the lead tag survived the site update by Friday.” An audit that ends in a clear, prioritized action list is worth ten audits that end in a vague sense of unease.

Prioritize your list by two things: how much money each fix protects or frees, and how easy it is to do. Knock out the high-impact, low-effort fixes first — they’re your quick wins and they’ll give you momentum for the bigger ones.

How often should you do a Google Ads audit?

Let’s make this sustainable, because a perfect audit you do once and never again isn’t a strategy — it’s a nice afternoon. The honest answer to how often you should do a Google Ads audit is: a light touch often, and a deep one on a regular rhythm.

Some things want frequent, small attention — glancing at the search terms report and adding negatives, checking that spend is pacing sensibly, making sure nothing’s suddenly stopped converting. A quick weekly or biweekly look keeps small leaks from becoming floods. Then a full, top-to-bottom audit like the one we just walked through fits nicely on a quarterly rhythm, or whenever something big changes — a website relaunch, a new product, a seasonal shift, a sudden change in performance.

The magic isn’t in doing it constantly; it’s in doing it regularly and calmly, with the same checklist each time so nothing slips. Consistency beats intensity here, just like it does almost everywhere in marketing.

Quick, honest note so we stay grounded: SocialBlaze is an organic social media scheduling and analytics tool — it’s not a Google Ads auditor or ad manager, and I’d never pretend otherwise. Think of it as the complement to your paid work: while your audit tightens the ads, SocialBlaze keeps your organic presence warm and consistent so the whole picture works together. Two different jobs, both worth doing well.

Let’s put your audit together

Take a breath, because look how far you just came. You started this with a vague, uneasy feeling that money was leaking somewhere, and now you have an actual, repeatable system. You verify your conversion tracking first, because everything else depends on it being true. You tidy your structure, read the confession of your search terms and build negatives, review your keywords and match types with clear eyes, check that your ads and assets earn their clicks, read Quality Score as a set of clues, align your bids and budgets with your real goals, make sure your landing pages keep the ad’s promise, and see whether your audiences are teaching you anything. Then you gather every leak into one prioritized action list and actually work it.

That’s how to do a Google Ads audit — not with anxiety, not with someone else’s benchmark numbers, but with a calm checklist and your own account’s honest data. The first time takes patience. Every time after that gets faster and, dare I say, a little satisfying, like tidying a room you’ve been avoiding and finally being able to breathe in it.

You’ve genuinely got this. Open your account this week, start with the tracking, and work the list. I have a feeling you’ll find a few things — and fixing them will feel really, really good.
