A Google Ads audit is not a list of “opportunities.” It is a diagnosis.
If the account is underperforming, there is a reason. Usually a boring reason:
- conversion tracking is wrong
- spend is going to irrelevant search terms
- automated bidding is optimizing noise
- campaign structure is muddled
- brand and non-brand are mixed, so ROAS looks better than reality
The worst audits I see are long and useless. They show screenshots of settings and call it insight. A good audit tells you what to fix first, and why that order matters.
This is the audit checklist I use when I take over an account. It is not theoretical. It is the quickest path to stopping waste and getting the account back under control.
If you want the ecommerce paid strategy layer, start with Google Ads for Ecommerce. If you want this executed, it starts on my Google Ads management page.
The One Rule of a Real Google Ads Audit
You do not audit for settings. You audit for outcomes.
Every audit item should answer one question:
Does this help the business generate profitable customers?
If the answer is no, it is noise.
Audit Step 1, Conversion Tracking Integrity (Do This First)
If conversion tracking is wrong, Smart Bidding is blind. It will optimize toward the easiest fake conversion at scale.
Google’s conversion tracking documentation is the baseline reference:
https://support.google.com/google-ads/answer/6095821
What I Check
- Are conversions firing on the correct pages and events?
- Are there duplicate conversions recorded for one real action?
- Is purchase value accurate (for ecommerce)?
- Are calls tracked as real calls, not just call clicks?
- Are micro conversions incorrectly set as “Primary”?
What a Red Flag Looks Like
- Conversions firing on page load without a real completion event.
- Multiple “Primary” actions that do not represent revenue.
- Inflated conversion counts that do not match reality.
What I Fix First
- Reduce “Primary” actions to the real business outcome.
- Ensure value is correct when value is the optimization signal.
- Validate tracking end to end with real test transactions or lead submissions.
If this step is wrong, nothing else matters.
Audit Step 2, Campaign Structure and Intent Separation
Most accounts waste money because structure is vague. Everything is mixed together, so you cannot diagnose performance cleanly.
What I Check
- Brand search isolated from non-brand search.
- Competitor terms isolated, if they are run at all.
- Search separated from Shopping and Performance Max.
- One service line per campaign when budgets support it.
What a Red Flag Looks Like
- One campaign “All Services” that mixes every keyword.
- Brand terms driving most conversions while non-brand bleeds budget.
- Performance Max reporting blended with everything else.
What I Fix First
- Create a dedicated branded campaign.
- Separate highest-intent non-brand from broad exploration.
- If ecommerce is involved, keep Shopping or PMax logic clean.
If you want the PMax-specific audit, I wrote it separately: Performance Max Campaigns Guide.
Audit Step 2.5, Account Settings That Quietly Burn Budget
Some of the most expensive mistakes live in account settings, not campaigns.
Here is what I check:
Networks and Expansion Defaults
For Search, I want to know if the campaign is spilling into placements the business did not intend. Many accounts run with defaults that expand reach before intent is proven. If you are running premium lead gen or a sensitive offer, this is a fast way to buy noise.
Location Targeting Mode
A classic waste pattern is location set to “presence or interest,” which pulls clicks from people outside your service area who merely show interest in it. For local and regional lead gen, I prefer “presence” based targeting, then I validate performance by location reports.
If the business is international, I still check whether the account is paying for irrelevant geos because settings were never tightened.
Ad Schedule and Lead Handling Reality
If leads only get handled during business hours, you should not pay aggressively outside those windows. That does not mean you shut off completely. It means you align bids to response capacity.
The audit question is simple, when a lead comes in at 9pm, does it get a response fast enough to convert? If not, do not overpay for that window.
Device Split and Mobile-First Intent
Many lead gen accounts perform differently by device. Mobile calls can be high intent. Mobile form fills can be low quality. Desktop can be slower but more qualified in some B2B categories.
I do not assume. I check device performance, then I adjust bids and landing experience. If the mobile landing page is slow or cluttered, the channel will look “expensive” for the wrong reason.
Account settings are not glamorous. They are where you stop paying for accidental traffic.
Audit Step 3, Search Term Hygiene (This Is Where Waste Hides)
Most advertisers do not check search terms often enough. Then they wonder why budget disappears.
Google’s negative keyword documentation is the baseline reference:
https://support.google.com/google-ads/answer/2453972
What I Check
- Query families that spend money but never convert.
- “Research” terms that look relevant but never produce buyers.
- Career and job queries.
- Free and cheap intent when the offer is premium.
What a Red Flag Looks Like
- High spend on ambiguous terms that attract the wrong buyer.
- Broad match pulling the account into unrelated industries.
What I Fix First
- Build an account-level negative keyword list for obvious irrelevance.
- Add campaign-level negatives for intent control.
- Tighten match type behavior by restructuring themes, not by praying.
The Search Term Workflow I Actually Use
People ask “how often should I check search terms?” The honest answer is, as often as the account needs. Early on, that can be every few days. Once stable, weekly is enough for many accounts.
My workflow is simple:
- Sort by spend, then scan for zero-conversion query families.
- Sort by conversions, then check whether those conversions are the right type and quality.
- Pull out patterns and turn them into negatives, not one-off whack-a-mole blocks.
If you add negatives randomly, you never finish. If you add them by pattern, you gain control quickly.
For lead gen, I also scan for queries that indicate the wrong buyer:
- “template”
- “course”
- “jobs”
- “free”
- “cheap”
- “DIY”
Premium services should not subsidize bargain intent.
Audit Step 4, Bidding Strategy and Data Sufficiency
Automated bidding can work. It can also amplify bad signals.
Google’s Smart Bidding overview is here:
https://support.google.com/google-ads/answer/2471185
What I Check
- Is the account using Target CPA or Target ROAS without stable conversion volume?
- Are bid strategies mixed in a way that creates inconsistent learning?
- Are campaigns constrained by unrealistic targets?
What a Red Flag Looks Like
- A campaign with low volume using an aggressive Target CPA, then failing to spend.
- A campaign optimizing for “leads” when most leads are junk.
What I Fix First
- Stabilize conversion signals.
- Use bidding that matches maturity.
- Remove targets that are forcing the system into starvation mode.
For lead gen accounts, offline conversion import is often the turning point. If you want the lead gen strategy layer, see my Google Ads for Lead Generation guide.
Audit Step 4.5, Attribution and “Conversion Credit” Reality
If you are reading performance inside Google Ads only, you are reading one perspective. It is useful, but it is not the whole story.
What I check:
- Is GA4 attributed revenue or lead volume directionally consistent with Google Ads?
- Are conversions being counted on view-through in a way that inflates performance?
- Are there multiple conversion actions that overlap, creating double credit?
This is where businesses get confused. They see Ads report one number, analytics report another, and they conclude tracking is “broken.”
Tracking is rarely perfectly aligned across systems. The goal is consistency and decision-making clarity. If one system shows growth and the other shows decline, something is wrong.
The fix is often boring:
- clean the conversion action list
- confirm primary actions
- verify tagging and event logic
- separate brand from non-brand so blended totals do not lie
Audit Step 5, Quality Score, Not as a KPI, as a Symptom
Quality Score is not a magic number. It is a symptom of relevance and landing page experience.
Google’s explanation is here:
https://support.google.com/google-ads/answer/6167118
What I Check
- Keywords with consistently poor Quality Score in high spend ad groups.
- Ad relevance mismatches, the ad does not match the query intent.
- Landing pages that do not confirm relevance quickly.
What a Red Flag Looks Like
- High CPC driven by low relevance, not competition.
- Landing pages that are generic and slow.
What I Fix First
- Tighten ad group intent.
- Align ad copy to the specific query family.
- Fix landing page relevance and speed on the money pages.
Audit Step 5.5, Landing Page Diagnostics (The Part Paid Teams Skip)
If the landing page is weak, you will pay more for worse traffic.
In audits, I check three landing page signals:
- Relevance, does the page confirm the query intent in the first screen?
- Friction, does the page make the next step obvious, or does it bury it?
- Speed, is the page fast enough on mobile to avoid losing the click?
I do not need fancy heatmaps to spot the obvious failures. If the page is generic, slow, and cluttered, it will convert poorly. Then the campaign learns that only branded traffic “works,” and you end up buying your own demand.
Landing pages do not need to be long. They need to be sharp.
Audit Step 6, Ads and Assets, Relevance Beats “Ad Strength”
Google likes “Ad Strength.” Fine. It is not your KPI.
Your KPI is qualified customers.
What I Check
- Do ads match the intent of the ad group?
- Are offers clear, including constraints and qualification?
- Are extensions present and meaningful, not filler?
What a Red Flag Looks Like
- Generic copy that tries to attract everyone.
- Ads that promise one thing and landing pages that deliver another.
What I Fix First
- Rewrite copy for clarity, not hype.
- Add extensions that reduce friction (calls, sitelinks, structured snippets).
- Ensure landing pages match the promise.
Audit Step 6.5, Assets and Extensions, Where Cheap Wins Hide
Extensions do not fix a broken strategy, but they do improve performance when everything else is competent.
What I check:
- Sitelinks that map to real intent splits (pricing, case studies, service details)
- Call extensions and call reporting when phone matters
- Structured snippets that reinforce offering scope
- Location extensions for local intent accounts
Google’s extension documentation changes by format, but the core principle stays the same. Make extensions useful. Do not add them as decoration.
If the account relies on lead gen, call tracking is often the biggest missing piece. I cover that in more detail in the lead gen guide: Google Ads for Lead Generation.
Audit Step 7, Budget Allocation and Business Priorities
Many accounts waste money because budget is not aligned to what the business wants to sell.
What I Check
- Spend by campaign mapped to revenue priority.
- High-margin offers supported, not starved.
- Low-margin offers constrained, not allowed to consume budget by converting easily.
What a Red Flag Looks Like
- Budget flowing to low-margin volume products.
- Brand taking most of the spend because it looks efficient.
What I Fix First
- Enforce budget rules that reflect margin and priority.
- Segment campaigns so product mix is controllable.
Audit Step 7.5, Change History, Find the Moment Performance Broke
Most accounts have a “before” and “after” moment. A change happened, performance shifted, and nobody connected the dots.
This is why I always review change history:
- bidding strategy changes
- conversion action changes
- budget changes
- keyword match type expansions
- new campaign types introduced
- landing page changes and tracking updates
Then I map changes to performance dates. This takes 15 minutes and saves weeks of guessing.
If you see performance collapse right after a conversion action switch, you do not need to “optimize ads.” You need to fix measurement.
Audit Step 8, Audience and Remarketing, Keep It Simple
Remarketing can help. It can also turn into a lazy crutch that masks weak acquisition.
What I Check
- Are remarketing audiences segmented by intent?
- Are high-intent visitors treated differently from casual visitors?
- Is frequency controlled where needed?
What a Red Flag Looks Like
- One catch-all remarketing audience that gets everything.
What I Fix First
- Segment remarketing by funnel depth.
- Keep remarketing spend honest, do not let it hide acquisition weakness.
Audit Step 8.5, Audience Expansion and “Automation Drift”
Automation drift is what happens when the account slowly stops matching the business.
Common causes:
- broad match expansions without negatives discipline
- PMax added without feed and brand controls
- lead forms added without lead quality controls
- conversion actions changed without review
In an audit, I look for drift patterns:
- rising spend with flat profit
- rising conversions with falling close rate
- rising branded share
Then I tighten the system, starting with measurement and intent separation.
Audit Step 9, Performance Max and Shopping, Separate the Logic
If Performance Max is part of the account, I audit it as its own system. Otherwise blended performance will mislead you.
What I check first in PMax:
- conversion integrity
- feed quality and product segmentation
- brand cannibalization risk
- asset group structure
If you want the full breakdown, it is here: Performance Max Campaigns Guide.
Audit Step 10, Product Mix and Margin Reality (Ecommerce Accounts)
If you manage ecommerce, campaign performance without product mix is incomplete.
What I check:
- Which products and categories are driving conversion value
- Whether the campaign is over-indexing on low-margin items
- Whether clearance inventory is eating budget because it converts easily
- Whether new arrivals are being starved
If you do not look at product mix, you can “optimize” the account straight into a margin problem.
This is where feed labels and segmentation matter. It is also where SEO and site structure matter, because category pages influence both paid landing experience and organic demand capture. If you want the full strategy context, see Google Ads for Ecommerce.
What I Fix in Week One (The Order That Actually Works)
If you are taking over an account, speed matters. Not reckless speed. Triage speed.
Week one priorities:
- Fix conversion tracking so the account stops learning garbage.
- Add negatives to stop obvious waste.
- Separate brand and non-brand so measurement is honest.
- Tighten structure so intent is controllable.
- Stabilize bidding and budgets based on real outcomes.
Then you optimize creative and landing pages, with clarity, not churn.
If you reverse the order, and you start by rewriting ads while tracking is wrong, you are polishing a broken system.
What the Audit Produces, a Plan You Can Execute
An audit is only valuable if it turns into an execution plan.
When I finish a Google Ads audit, the output is deliberately short and usable:
- A root-cause list, not a symptom list.
- A week-one fix list focused on stopping waste and stabilizing measurement.
- A week-two and week-three plan focused on scaling what works by intent cluster.
- A measurement note that defines success for the business, profit, qualified leads, new customers, not vanity volume.
This forces hard decisions. If the business wants premium clients, we stop buying cheap intent. If the business needs volume, we accept a wider query set but enforce qualification and offline signals.
The audit is the moment you decide what the account is allowed to be. After that, optimization is just execution.
I also assign ownership and timing. “Fix tracking” is not a task. “Replace primary conversion action, validate with test lead, and confirm no duplicate counting” is a task. Each fix gets an owner, a due date, and the outcome we expect to see if it worked. I keep the list short enough that a team can execute it in one sprint. That is how you avoid audit theater, a document that looks professional and changes nothing.
It is boring. It works. Most accounts do not need genius, they need discipline and clean measurement.

FAQ
What is a Google Ads audit and what should it include?
A Google Ads audit is a diagnosis of why performance is weak or spend is wasted. It should start with conversion tracking integrity, then move to structure, search terms, bidding, and budget allocation. A good audit tells you what to fix first and why, not just what settings exist.
How often should I audit a Google Ads account?
At minimum, do a light audit monthly and a deeper audit quarterly. Any major change, new tracking, new campaign types, new product feed, also triggers an audit. Accounts drift over time, especially with automation, so the check is not optional.
Why do Google Ads conversions look high but sales are low?
Because tracking is wrong, conversion actions are not aligned to revenue, or the account is optimizing for low-quality leads. Fix the primary conversion action, validate tracking end to end, and use offline conversions for lead gen when possible so bidding learns what closes.
What is the most common Google Ads mistake you see?
Running automated bidding on bad data. If the conversion signal is polluted, the algorithm scales the pollution. The second most common mistake is mixing brand and non-brand, which inflates ROAS and hides acquisition weakness.
Can you audit Performance Max campaigns the same way as Search?
No. PMax is a different system with different controls and different reporting. You audit conversion integrity, feed quality, asset group structure, and brand cannibalization risk first. Then you tighten inputs, because that is where control lives.
If this maps to problems you recognize, the next step is to run the audit like triage and fix the system in the right order. That is the work I do on my Google Ads management page.
