The Google Ads Account Audit Checklist, In the Order I Actually Run It

Every checklist ranking for “google ads account audit” opens with the same step: review your goals, then your account structure. I read the top pages before writing this, and not one of them puts conversion tracking first, not one mentions enhanced conversions, and not one mentions Performance Max. Those are not small omissions. They are the three things most likely to be wrong in an account handed to someone new, and checking structure before tracking means every other finding in the audit is built on a number that might already be false.

So this is the order I actually run, with what a professional audit costs and when it is worth paying for one instead of working the list yourself.

How much does a Google Ads account audit cost?

A Google Ads audit from a paid consultant runs on one of three pricing models, and the model tells you more about the incentive than the price does.

Flat fee is also why the order below matters to a paid audit specifically, not just a DIY one: the report is the deliverable, and a report that reviews structure before confirming the numbers behind it are real is a report built on a guess.

Why the order of the checklist matters more than the checklist

Checklists get written in the order a new hire would explore an account: zoom out, read the goals, then the structure, then work down to the detail. That is a reasonable way to learn an account. It is a bad way to audit one, because every judgment you make about structure, bidding or keywords is downstream of whether the conversion data driving those decisions is accurate.

Google’s own guidance backs the sequencing, even if it does not frame it as an audit order: its support documentation on tracking sales treats confirming that conversions are set up correctly as the step before anything else is trusted.

Step 1: Conversion tracking, checked before anything else

Start by listing every conversion action in the account and checking three things for each one: does it fire once per real event, does the value attached to it match reality, and does it match a business outcome someone would recognize. A “Page view” conversion counted as a sale is the single most common thing I find in an inherited account, and it makes every number above it — cost per conversion, ROAS, Smart Bidding’s own learning — wrong in the same direction.

• Check for duplicate firing. A tag that fires on page refresh or on a thank-you page a customer can revisit will inflate every conversion count above it.
• Check the conversion source. If conversions are imported from GA4 rather than tracked natively, confirm which GA4 events are mapped, and check for the same event appearing in two places under different names.
• Check the value. A fixed conversion value on a store with variable order sizes makes ROAS meaningless in either direction.

Do this before opening a single campaign. Everything else in this list is diagnosis built on top of this number being right.

Are you actually using enhanced conversions?

None of the checklists ranking for this term mention enhanced conversions, which is the clearest gap in the category. Google describes enhanced conversions as a way to improve the accuracy of conversion measurement by supplementing existing tags with hashed first-party data such as email address. Without it, an account is relying entirely on third-party cookies that browsers increasingly block, and the account’s own reported conversion count quietly understates what actually happened.

Check whether enhanced conversions are enabled for web, and whether the match rate Google reports for each conversion action is meaningfully above zero. A tag that exists but was installed before enhanced conversions were added to the account will often still be running on cookies alone and nobody noticed.

Step 2: Account and campaign settings

Only once tracking is confirmed does the account itself become worth looking at. Location and language targeting, device bid adjustments, ad schedule, and whether automatically applied recommendations have been silently switched on all belong here. Automatically applied recommendations are worth a specific check: Google Ads can apply certain changes without asking, and an inherited account frequently has several turned on that nobody chose.

Step 3: Keywords, negatives and search terms

Pull the search terms report for the full history available and look for three patterns: queries with real spend and zero conversions, queries that belong to a different product line entirely, and branded queries leaking into non-brand campaigns. A thin or absent negative keyword list is the fastest-to-fix, highest-confidence finding in most audits, which is also why it is the one every checklist gets right.

Step 4: Ad groups, ad copy and Quality Score

Check ad group tightness — how many distinct themes are crammed into one group — and how many active ad variations each group is testing. Low Quality Score on a keyword is a symptom, not the problem; the cause is almost always ad relevance or a landing page mismatch, and fixing the symptom without finding the cause just moves the same problem to a different keyword next month.

Is Performance Max quietly eating your other campaigns?

Performance Max gets left out of audit checklists for the same reason it gets left out of most campaign-level thinking: it is a single campaign that spans Search, Shopping, Display, YouTube and Gmail inventory at once, so there is no separate “PMax audit” section in most people’s mental model of an account. Google’s own documentation describes it as a campaign type built to complement keyword-based Search campaigns, not replace them, which is exactly the setup that goes wrong without a brand exclusion in place.

Step 5: Account structure, checked last

Structure goes last, not first, because a well-organized account built on broken tracking is still a broken account, and a messy account with clean tracking is at least telling the truth about what is happening. Naming conventions, campaign grouping by margin or product line, and whether Shopping and Search are competing for the same queries all matter — they are just not the first thing that can be wrong, so they should not be the first thing checked.

I ran this exact order on The Lifeguard Store‘s account before it scaled from $1,513 a month to $14,597 a month over 24 months at a 17.5x blended return. Tracking got checked before the budget got raised, not after, because the whole point of raising a budget is trusting the number that tells you whether it worked.

Who should not pay for a Google Ads audit

A paid audit is wrong for three situations, and the honest answer costs me the sale in all three:

1. The account is less than six weeks old. There is not enough conversion history for Smart Bidding to have learned anything yet, so most of what an audit would find is “too early to tell,” which is not worth paying for.
2. Monthly spend is under roughly $1,000. The checklist above still applies, but running it yourself in an afternoon costs less than the smallest flat-fee audit on the market, this one included.
3. Nobody on the team will act on the findings. An audit is a list of fixes, not a fix. If there is no one to implement them, the report is a very specific way to spend money on paper.

Outside those three, running the checklist yourself in this order is free and takes an afternoon. Paying someone buys you the parts that are hard to do to your own account: noticing what you stopped seeing because you built it, and a second set of eyes on tracking before the rest of the audit leans on it.

How long does a Google Ads account audit take?

A manual run through this order takes two to four hours for most ecommerce accounts, longer for anything running Performance Max across more than a handful of product categories, since asset group performance has to be pulled apart by hand. Tracking verification alone is usually under an hour. Structure, which most checklists treat as the main event, is the fastest section once everything above it has already been confirmed clean.

The rest of what I write about running Google Ads for ecommerce brands starts from the same assumption this checklist does: fix the number you are trusting before you fix the account built on top of it.
