A Google Ads audit is a structured review of your account to find where money leaks and which fixes will move results the most. A good audit checks whether conversion tracking is accurate, whether the account is structured for honest reporting, and where spend goes to traffic that will never convert. The output is a short list of changes ranked by impact, not a 40-page report nobody reads.

This is the same checklist we run inside Adfure. Work through it in order, because each section depends on the one before it. There is no point optimizing bids on data you cannot trust.

How to audit a Google Ads account, section by section

Below is a full PPC audit walkthrough. Tick each item. Anything you cannot confirm is a finding.

1. Conversion tracking and GA4

Everything downstream depends on this. If conversions are wrong, your bidding optimizes toward the wrong thing.

  • Confirm your primary conversion action is actually firing on the real success event (a purchase or a qualified lead), not a page view or a button click that anyone can trigger.
  • Check for double-counting. The same conversion logged by both Google tags and GA4 imports, or counted on every page load, inflates results and misleads bidding. Deduplicate.
  • Mark only meaningful actions as Primary conversions. Demote soft signals (newsletter signups, time on page) to Secondary so bidding does not chase them.
  • Verify conversion values are passing through if you run an e-commerce or value-based account. No value means no honest ROAS.
  • Confirm GA4 and Google Ads agree on order volume within a reasonable margin. Large gaps point to a tracking or attribution problem.

Many accounts run for months without proper conversion tracking, which quietly poisons every other decision. Fix this first.

2. Account structure

Structure is what makes reporting honest and control possible.

  • Split brand and non-brand campaigns. Brand traffic is cheap and converts well; leaving it mixed in flatters your numbers and hides how acquisition is really doing.
  • Keep campaign types separate: Search, Shopping, Performance Max, Display, and Video in their own campaigns. Mixing them blurs reporting and lets one channel cannibalize another.
  • Use a consistent naming convention so anyone can read the account at a glance.
  • Watch where Performance Max overlaps Search and Shopping. PMax tends to absorb credit, especially for brand queries, so the rest of the account looks weaker than it is.

3. Keywords and search terms

This is where most wasted spend hides in plain sight.

  • Run a search-term mining pass. Read the actual queries you paid for, not the keywords you bid on. Irrelevant terms get added as negatives; good ones get promoted.
  • Maintain negative-keyword hygiene. Negative keywords are the single biggest lever for cutting waste in most search accounts. Build and update shared negative lists.
  • Review match types. Broad match can reach buyers, but unmanaged broad match is a common way to burn budget on loosely related searches.
  • If you run broad match, confirm there is real control around it: strong negatives, reliable conversion data feeding Smart Bidding, and frequent search-term reviews.

4. Settings traps

Default settings are set to spend your money widely, not efficiently. Check each one.

  • Turn off Search Partners unless you have proven it converts for you. It is on by default and often spends without payback.
  • Turn off the Display Network on Search campaigns. “Search with Display” quietly pushes budget into low-intent placements.
  • Check location targeting. Set it to people in your locations, not people merely interested in them, or you will pay for the wrong geography.
  • Review device performance and adjust where one device clearly underperforms.
  • Look at the ad schedule. If conversions cluster in certain hours or days, your spend should reflect that.

5. Bidding strategy fit

The right bid strategy depends on how much data the account actually has.

  • Match the strategy to volume. Target ROAS and Target CPA need a steady stream of conversions to work; on thin data they get erratic. Lower-volume accounts often do better starting on Maximize Conversions before adding a target.
  • Sanity-check your targets. A tROAS or tCPA set far from real performance will choke delivery or chase unprofitable traffic.
  • Respect learning periods. Frequent target changes restart learning and keep campaigns unstable. Change less, and give each change time.

6. Ads and assets

You can win the auction and still waste the click with a weak ad.

  • Check Responsive Search Ad strength: enough distinct headlines and descriptions, your keywords reflected in the copy, and a clear offer.
  • Confirm sitelinks, callouts, and structured snippets are in place. Missing assets mean a smaller, less compelling ad.
  • For Performance Max, review each asset group: real images, logos, and video rather than auto-generated filler, grouped by theme.

7. Budget pacing and wasted spend

  • Check whether budget-limited campaigns are the ones you actually want to scale, or whether weak campaigns are eating the budget.
  • Find campaigns spending with little or no conversion volume over a meaningful window. That spend should be cut or restructured.
  • Re-read the spend after splitting brand and non-brand. The honest non-brand picture often looks different from the blended one.

8. Audiences and exclusions

  • Add exclusions for existing customers or converters where repeat purchase is not the goal, so you stop paying to reach people who already bought.
  • Layer remarketing and first-party audiences as observation first, then bid on what proves out.
  • Exclude placements and audiences that consistently spend without converting, especially on Display and PMax.

The biggest sources of wasted spend

If you only have an hour, start here:

  • Broken or misconfigured conversion tracking that misleads bidding.
  • Thin negative-keyword lists, letting irrelevant searches drain budget.
  • Search Partners and Display left on inside Search campaigns.
  • Unmanaged broad match with no negatives or reliable conversion data behind it.
  • Brand and non-brand mixed together, hiding what acquisition really costs.

DIY audit vs an automated audit

A manual audit is thorough but slow, and it is only as current as the last time someone sat down to do it. Accounts drift daily: new search terms appear, costs shift, a setting gets toggled back on.

An automated audit catches that drift continuously. Adfure is a profit-first AI media buyer for Google, Meta, TikTok, and LinkedIn. It is judgment-first: it reads your account the way an experienced buyer would, benchmarks against your own past results rather than generic averages, and watches the account around the clock. You keep full account ownership, it never touches your card, and nothing changes without your approval.

The free AI account audit is the fastest way to see this in action. Connect Google in read-only mode and you get a plain-language list of where spend is leaking and the highest-impact fixes, ranked. See the rest of what it does on the features page. If you are auditing Meta too, our guide on how to stop wasting money on Facebook ads covers the same ground there, and if you are setting targets, read what a good ROAS actually is first.

Frequently asked questions

How long does a Google Ads audit take?

A careful manual audit of a mid-sized account usually takes a few hours to a day, depending on how many campaigns and how messy the structure is. An automated audit like Adfure’s returns a first read in minutes.

How often should I audit my account?

A deep manual audit once a quarter is a sensible baseline, but accounts drift daily. Continuous monitoring catches new wasted search terms, setting changes, and cost shifts as they happen, which is why ongoing watch beats occasional deep dives.

What is the single biggest source of wasted spend?

For most search accounts it is poor negative-keyword hygiene combined with unmanaged broad match, followed closely by Search Partners and Display being left on inside Search campaigns. Broken conversion tracking is worse, because it corrupts every other decision.

Do I need to give up access to my account for an audit?

No. A proper audit needs read-only access at most. With Adfure you connect Google read-only, keep full ownership of the account, and nothing is changed without your approval.

Can I trust an AI to audit my Google Ads?

An AI audit is good at reading the whole account quickly and consistently, which is exactly where manual reviews get tired and skip steps. Adfure benchmarks against your own results rather than generic averages and surfaces findings for you to approve, so judgment stays with you.
