The average Google Ads account wastes between 20% and 40% of its budget. That’s not a scare stat we made up — it’s what we see consistently when we open accounts for the first time. And the worst part? Most of that waste is invisible if you only look at the metrics your agency puts in the monthly report.
A real Google Ads account audit doesn’t just look at ROAS and click-through rate. It goes three layers deeper: into campaign structure, match type logic, conversion tracking integrity, bidding strategy alignment, and whether the account is even measuring the right things. This guide walks you through exactly how to do that — step by step, in the order that actually matters.
- Conversion tracking is the first thing to audit — everything else is meaningless if it’s broken or double-counting
- Campaign structure problems are the root cause of most efficiency issues, not just poor creative or bad keywords
- Match type abuse — especially unchecked broad match — is the single fastest way an account bleeds budget invisibly
- Bidding strategy choice only works correctly when it’s aligned with conversion volume, target, and account history
- A proper PPC audit checklist covers at least seven distinct layers — surface-level performance reports miss most of them
Step 1: Start With Conversion Tracking — Because Everything Else Is Built on This Foundation
Before you look at a single campaign metric, verify that the account is measuring conversions correctly. This sounds basic. It is basic. And roughly 60% of accounts we audit have at least one material tracking error.
The most common problems: duplicate conversion actions that double-count the same event, “include in conversions” checked on actions that shouldn’t drive bidding (like page views or phone number clicks that never get answered), and conversion tracking that fires on the thank-you page load rather than an actual form submission — which means every accidental refresh counts as a lead.
Here’s what to check specifically:
- Go to Tools → Conversions and look at every active conversion action. Ask: does each one represent a real business outcome?
- Check the “Include in Conversions” column. Micro-actions like scroll depth or video views should almost never be checked here — they’ll confuse Smart Bidding into optimizing for the wrong thing.
- Look at the “Source” column. Anything pulling from Google Analytics instead of a direct Google tag is higher risk — GA4 session-based attribution behaves differently and can cause discrepancies.
- Cross-reference your conversion numbers against CRM data for the same time period. If Google says you got 80 leads last month and your CRM shows 30 real inquiries, you have a tracking problem — not a performance win.
If you’re not using Enhanced Conversions, set that up as part of your audit remediation. It closes the measurement gap created by cookie restrictions and improves Smart Bidding signal quality significantly.
For accounts running lead gen where the close rate matters, this is also the point where you should evaluate whether offline conversion tracking is in place. Optimizing for submitted leads when only 10% of them close is how you get a ton of cheap, useless form fills.
Step 2: Audit Campaign Structure — The Architecture Either Supports or Fights Your Goals
Good campaign structure is invisible — it just works. Bad structure creates budget cannibalization, keyword conflicts, Quality Score suppression, and reporting that makes it impossible to know what’s actually driving results.
The first thing to look for: are campaigns segmented by intent, not just by product or service? A campaign mixing “buy running shoes” and “what are the best running shoes for flat feet” in the same ad group is mixing commercial and informational intent. Those need different bids, different ads, and different landing pages. Grouping them together means you’re overpaying for informational clicks or underbidding on high-intent ones — usually both.
A solid Google Ads account structure typically separates:
- Branded vs. non-branded — always separate campaigns so you can control budgets and read data cleanly
- High-intent (bottom-funnel) vs. research-stage (mid-funnel) — different landing pages, different messaging, different bids
- Competitor keywords — these need their own campaign with carefully written copy and different landing page expectations
- Geographic segments — if performance varies wildly by region, you need the ability to bid differently, which requires separate campaigns
Also check for keyword overlap between campaigns. If the same or similar keyword exists in two different campaigns, they’ll compete against each other in the auction. Google’s “Auction Insights” won’t tell you this — you need to manually cross-reference keyword lists or use a script. Our account structure guide goes much deeper on this if you want the full framework.
Step 3: Tear Apart the Keyword Strategy — Match Types, Search Terms, and Negative Keywords
This is where most accounts are hemorrhaging money. The search terms report tells the truth that the keywords tab hides.
Pull your search terms report for the last 90 days. Filter to clicks above a threshold (say, 5+ clicks). Now look at what you’re actually paying for. In almost every account we audit, we find dozens of irrelevant queries eating real budget — and nobody’s been reviewing this report regularly enough to catch them.
Match type is the underlying culprit. Broad match without tight negative keyword lists and strong ROAS history is a budget leak, not a volume strategy. We’ve written at length about when broad match actually works — and it almost always requires Smart Bidding with sufficient conversion data before it starts behaving itself. If you’re running broad match on a new account or a campaign with fewer than 50 conversions per month, you’re feeding the algorithm junk data and paying for it.
On the negative keyword side, check for:
- A negative keyword list at the account level (not just campaign level) — if it doesn’t exist, that’s a red flag
- Whether competitor brand names are negated from non-competitor campaigns
- Whether irrelevant industry terms that share words with your keywords are blocked (a law firm bidding on “injury lawyer” should have “personal trainer” negated, as absurd as that sounds — we’ve seen it)
- Whether the negative list has been updated in the last 30 days — a static negative list from setup day is almost worthless six months later
If wasted spend is your biggest concern coming out of this audit, the wasted spend reduction framework covers the exact remediation steps in detail.
Step 4: Review Bidding Strategy Alignment — Smart Bidding Only Works When the Inputs Are Right
Smart Bidding is not a “set it and profit” system. The algorithm is only as good as the conversion data it’s optimizing toward. And if the inputs are wrong — wrong conversion actions, too few conversions, misaligned targets — Smart Bidding will confidently optimize you into a ditch.
During your audit, check each campaign’s bidding strategy against these criteria:
- Target CPA campaigns need at least 30–50 conversions per month (per campaign, ideally) before tCPA can do anything intelligent. Below that threshold, you’re usually better on Maximize Conversions while you build volume.
- Target ROAS campaigns need even more data — we typically want 50+ conversions per month and a stable, realistic ROAS target. If you set a tROAS target above your historical average by more than 20%, the campaign will throttle spend trying to hit an unachievable target.
- Maximize Clicks on anything except branded or awareness campaigns is almost always wrong. It optimizes for cheap clicks, which are usually cheap for a reason.
- Check whether any campaigns recently switched bid strategies — Smart Bidding needs a 2–4 week learning period after any significant change, and performance during that window looks terrible even when everything is fine. Don’t make knee-jerk decisions during a learning phase.
For a deep dive on how Smart Bidding actually makes decisions (and when to override it), this breakdown of how Smart Bidding actually works is worth reading before you touch any bid strategy settings.
Step 5: Audit Ad Creative and Landing Page Alignment — The Gap Where Conversions Die
This step is the one most PPC-only audits skip. They look at CTR and call it creative analysis. That’s not an audit — that’s a vanity metrics tour.
The real question is: does the message in the ad match the experience on the landing page? Message match — or the lack of it — is one of the fastest ways to tank conversion rate while your click data looks perfectly healthy.
For Responsive Search Ads (RSAs), check:
- How many active RSAs per ad group — you should have 2–3, not 1, so Google can test combinations
- Asset performance ratings in the “Assets” view — any headline or description rated “Low” for 30+ days should be replaced
- Whether your top headlines actually contain the search term or close variant — ads that reflect the user’s query convert better, full stop
- Ad strength — “Poor” or “Average” usually means you’re relying on too few unique headlines or too much repetition across assets
On the landing page side: if every ad in the account sends traffic to the homepage, that’s a structural problem, not a creative one. Homepages are for browsers. High-intent searchers need a dedicated page that speaks to exactly what they searched for. Check whether landing pages match campaign themes, include a clear and singular call to action, and load in under 3 seconds on mobile. Our landing page best practices guide covers this in detail — it’s worth running your pages through that checklist as part of any Google Ads review.
Step 6: Check Account Settings, Extensions, and the Things Nobody Looks At
This is the layer most audits treat as a formality. It shouldn’t be. Campaign settings problems are silent killers — they don’t throw errors, they just quietly drain performance.
Geographic targeting is the most common setting mistake. Go to your campaign settings and look at the “Location options” section. The default setting targets people who are “in or regularly in OR interested in” your target location. That second part — “interested in” — means someone in another country searching for “plumber in Denver” can see your ad. For local service businesses, this is a significant wasted spend source. Change it to “Presence: People in or regularly in your targeted locations” only.
Also check:
- Search partners and Display Network — these are opt-in by default in Search campaigns, and Display Network especially tends to drive low-quality traffic that inflates impression and click counts without contributing to conversions. Audit the performance data and consider disabling unless you see clear evidence they’re contributing.
- Ad scheduling — are you running ads 24/7 when your business only operates and converts during certain hours? Especially relevant for phone-call-dependent businesses.
- Ad extensions (now called Assets) — sitelinks, callouts, structured snippets, call extensions, and lead form extensions should all be present and actively used. An account with only basic text ads and no assets is leaving click-through rate (and Quality Score inputs) on the table.
- Audience lists applied as observation — at minimum, your remarketing audiences, customer lists, and in-market segments should be applied in observation mode so you can see performance data and apply bid adjustments. If there are zero audience layers, you’re flying blind.
Step 7: Pull the Performance Data and Build a Prioritized Action List
The output of a good audit isn’t just a list of problems — it’s a ranked list of fixes ordered by revenue impact.
Not every issue deserves the same urgency. Broken conversion tracking gets fixed today, because every day it’s broken is a day your bidding algorithm makes decisions on corrupted data. A low-performing RSA headline can wait a week. A misaligned geographic setting on a $10,000/month campaign gets fixed this afternoon.
Structure your findings into three tiers:
- Critical (fix within 24–48 hours): Conversion tracking errors, budget misconfiguration, campaigns sending all traffic to irrelevant pages, bidding strategies with wildly misaligned targets
- High priority (fix within 1–2 weeks): Match type problems, missing negatives, structural issues causing keyword cannibalization, missing ad assets
- Optimization (ongoing): Ad creative testing, landing page optimization, audience bid adjustment refinement, search term list management
If you’re auditing an account you’ve just inherited — either from a previous agency or from a DIY period — understanding what good account management looks like in the first 90 days gives you a useful benchmark for how far behind (or ahead) you actually are.
Frequently Asked Questions
How long does a Google Ads account audit take?
A surface-level audit — checking campaign settings, basic structure, and top-level performance — takes 2–4 hours. A thorough audit that includes conversion tracking verification, full search term analysis, creative review, and landing page assessment takes 8–16 hours for a mid-size account. If someone tells you they can audit your account meaningfully in 30 minutes, they’re doing a demo, not an audit.
How often should I audit my Google Ads account?
A full structural audit should happen at least twice per year. But a lightweight monthly review — checking search terms, conversion data, budget pacing, and any new campaign changes — should be part of your standard operating rhythm. We cover the monthly maintenance checklist in our Google Ads optimization checklist.
What’s the most common problem found in a PPC audit?
Conversion tracking errors, by a wide margin. The second most common: match type abuse — usually broad match keywords running without adequate negative keyword lists or sufficient conversion history for Smart Bidding to work correctly. These two issues account for the majority of wasted spend we find in new accounts.
Can I audit my own Google Ads account, or do I need an agency?
You can absolutely audit your own account using this framework. The value a third-party audit adds is objectivity — it’s easy to miss problems in an account you built and have looked at every day for two years. A fresh set of experienced eyes will find things you’ve normalized. That said, if you go through this checklist honestly, you’ll surface most of the material issues yourself.
What should a Google Ads audit cost?
A free audit from an agency is usually a sales tool — which isn’t inherently bad, but know what it is. A paid independent audit from an experienced practitioner typically runs $500–$2,000 depending on account complexity. Audits from larger agencies can run higher. The question isn’t what it costs — it’s whether the findings are specific, prioritized, and actionable. Vague recommendations like “improve your ad relevance” are worth nothing.
What’s the difference between a Google Ads audit and an account review?
Terminology varies, but in practice: a review tends to be higher-level and performance-focused (how are metrics trending?), while a full audit goes into account architecture, settings, tracking integrity, and structural decisions. You want both — but if you only get one, get the audit. Metrics without structural context don’t tell you why something is happening or what to do about it.
Before You Walk Away From This Audit, Ask Yourself One Honest Question
If you went through this framework and found problems — conversion tracking that’s off, match types that are leaking budget, landing pages that don’t match the ad — how confident are you that your current setup (or current agency) will actually fix them?
There’s a difference between an agency that sends you a monthly performance report and an agency that’s actively auditing the account against this kind of framework on a regular basis. If you’re not sure which one you have, that uncertainty is worth resolving.
Knowing the signs your Google Ads agency isn’t performing can help you tell the difference — and it’s a faster read than a full audit if you just need a gut check right now.
If you want a second opinion on what you found — or want us to run this audit on your account directly — we offer a free account review for businesses spending at least $3,000/month on Google Ads. No obligation, no sales pressure. Just an honest look at what’s working, what isn’t, and what we’d do differently. Request your free Google Ads account review here.
