A Google Ads account audit should prove the account's data can be trusted before it changes anything. This is the method we run on inherited accounts, two weeks from access to a testing roadmap.
It assumes the business should be running Google Ads at all. If that's still open, run the nine checks first: an audit can't rescue an account that fails them.
Why does the audit start with measurement?
Because Smart Bidding does exactly what the tracking tells it to. Every bid, budget and automated decision in the account runs on what it's been told a conversion is. If every form fill counts the same, Smart Bidding hunts down the cheapest form fills available, and the people behind them are rarely your buyers. If a page view is marked Primary, it buys page views. No restructure fixes an account aimed at the wrong target, so the first days change nothing that isn't broken.
The sequence holds on every account: watch before touching anything, record a baseline, repair the tracking, cut the waste nobody would defend, and restructure last, with a written reason for each change.
What happens in each week of the audit?
The first week establishes whether Google is buying the traffic the business believes it's buying. The second makes controlled changes. Here's the checklist we work from, yours to keep whether you hire us or not.
GOOGLE ADS ACCOUNT AUDIT: THE TWO-WEEK CHECKLIST
Days 1-2 Access and tracking
[ ] Access to Google Ads, GA4, GTM, Search Console,
Merchant Center, the CMS, and the CRM or lead system
[ ] Each conversion action: Primary or Secondary,
firing once, and never optimizing toward page
views or button clicks
[ ] Calls tracked, UTMs surviving, enhanced
conversions configured
[ ] Billing, timezone, auto-tagging, exclusions, and
whatever rules, scripts and experiments a previous
agency left running
Days 2-4 Where the money goes
[ ] Performance by campaign, search term, device,
location, time of day, landing page and
conversion action
[ ] 30 days, 90 days, six months, and year over year
[ ] Change History read against every swing in
performance
Days 3-5 Search terms and traffic quality
[ ] Search terms, match types, negatives and
location settings
[ ] Search Partners, Display expansion, Performance
Max behavior
[ ] Brand leakage, competitor terms, irrelevant
searches
[ ] Lead quality set beside lead cost
Days 4-6 Audiences
[ ] Visitors, pricing-page visitors, form starters,
past customers
[ ] Exclusions, so people who already bought don't
see the intro offer
Days 5-7 Structure and economics
[ ] Campaigns mapped to intent and margin
[ ] Budgets matched to the business's priorities
Week 2 Controlled changes
[ ] Fix conversion actions, negatives, locations,
budgets, broken ads
[ ] Record the baseline before each change and date
every change
Deliverable: clean measurement, a map of where the
spend goes, and a prioritized testing roadmap
Three items do most of the work. Change History is the most useful screen in an inherited account, because it lines up every performance swing against what somebody changed. The search terms report is where wasted spend usually turns up: traffic the account pays for that nobody meant to buy. And lead quality sits next to lead cost from day one, since ten $40 leads that sales hates cost more than five $70 leads that close (illustrative figures).
Every change also gets a dated line in a decision log kept outside Google Ads. Change History will show that someone switched off Saturday ads in March. Only the log says why: weekend leads were closing at a third of the weekday rate (illustrative figures). Without that line, the next person to run the account switches Saturdays back on. Our Account Operating Thesis kit is the template we keep it in.
How should the account be structured?
As consolidated as the data allows, with each level doing one job:
- A campaign separates budget, economics or intent.
- An ad group separates the message or the landing page.
- A keyword is a variation of the same intent.
Five campaigns with enough data to decide anything beat twenty-five campaigns getting three conversions a month. The working test for splitting an ad group: if it deserves a different ad or a different landing page, it deserves its own group, whether it holds six keywords or twenty-five.
Match types start tight. Exact and phrase dominate a new account because they produce clean search-term data. Broad match comes in once four things hold: reliable conversion tracking, enough conversion volume for Smart Bidding to learn, a working negative-keyword process, and a conversion that matches a real business outcome. The expensive combination is broad match, Maximize Conversions, a large budget and bad tracking, all at once.
Search stays the default for cold acquisition, because the searcher is stating what they want. Performance Max earns budget where there's good conversion data, solid creative, proper exclusions and a clean feed, and a new lead-gen account rarely has all four. Optimization Score deserves the same skepticism. It measures how closely the account follows Google's recommendations, which makes a green score a compliance number, so budgets never move to chase it.
What should a Google Ads report lead with?
The business result, then the channel metrics, then the decisions. The top line is whatever sits highest on this ladder that the account can reach: revenue, closed customers, qualified opportunities, qualified leads, raw leads. Everything below the top available rung is diagnostic.
A monthly report that earns its place covers spend, qualified leads and opportunities, customers or revenue, cost per qualified lead or customer, non-brand performance with brand shown separately, the search terms that helped or hurt, budget shifts, tests completed and what they taught, next month's changes, and any tracking, sales, landing-page or offer problem holding the account back. It should answer three questions in five minutes: what happened, why, and what happens next.
Impressions, clicks and CTR never lead, because they're easy to buy. A conversion count that doesn't say what the conversions were can't lead either: a phone click, a PDF download and a closed customer aren't interchangeable. Blended ROAS is the worst offender. Picture a report showing $20,000 in spend, $200,000 in revenue and a 10-to-1 return, where $160,000 of that revenue came from people searching the company's own name (illustrative figures). Every number in it is accurate, and the story it tells is wrong. The brand vs non-brand splitter takes a Google Ads export and shows what your own blended number is carrying.
Failed tests go in the report as failed tests, with the reason, the cost of the lesson and the decision to stop.
What changed in Google Ads in 2026?
Google now builds more of each ad from your website, your business information and your conversion data, and needs less from your keyword list. These are the changes that matter for an audit, each checked against Google's own pages on September 29, 2026 (sources at the end):
- AI Max for Search launched in May 2025 as a one-click feature suite inside Search campaigns. It expands matching through broad match and keywordless technology drawn from your keywords, ads and website, and it can write new ad text and send clicks to other pages on your site. Campaigns using the campaign-level broad match setting or automatically created assets began upgrading to it in September 2026, and Dynamic Search Ads follow from February 2027, a date Google pushed back in June.
- On Lens, AI Mode, AI Overviews and auto-complete searches, Google doesn't treat the search as technically identical to a keyword, so your keywords may not get priority. Exact match no longer routes every query.
- Ads can appear above and below AI Overviews in all 200-plus markets that have them, and inside AI Overviews in English in 12 countries, including the US. You can't target the placement or opt out, the ads report as Top Ads, and reaching them requires AI-powered targeting: broad match, AI Max, Performance Max, Shopping or Dynamic Search Ads.
- Enhanced conversions for web and for leads are being merged into one setting. Since April 2026 Google Ads accepts customer data from website tags, Data Manager and API connections at once, and since June 15, 2026 offline conversion imports go through the Data Manager API.
- Performance Max now takes up to 50 search themes per asset group. It's worth testing where the conversion data is good, with a budget it has to earn.
- For traffic from the European Economic Area, consent signals decide whether measurement, personalization and remarketing keep working. For a US-only local business, Consent Mode isn't the reason the campaigns underperform.
- AI Mode passed one billion monthly users in May 2026, and Google is testing Conversational Discovery ads inside it. The controls for an AI Mode strategy don't exist yet, so nobody can sell you one.
Three of those change the audit's central question. Reaching Google's newest inventory means giving up keyword control, that inventory reports without a separate breakdown, and your website now works as a targeting input. You have less control and less visibility than two years ago, and more of your paid performance depends on work that looks like SEO: accurate business data, strong pages, and conversion signals that describe real customers. So the audit asks what the account is teaching Google about the business.
How do Google Ads and SEO work together?
As one search program with two ways of capturing demand. Paid gives SEO fast feedback: the terms that convert, their click-through rates, and the words buyers use close to purchase, within weeks. A query converting well in paid while the site ranks eighteenth organically is an obvious SEO target. SEO returns the favor with Search Console queries already earning impressions, especially the ones sitting at positions 4 to 15, which paid can test for commercial value in days.
Running both brings one conflict, and it's ours to name. SEO raises visibility, visibility raises branded searches, and a brand campaign converts them, which makes paid look extraordinary. That's credit taken twice. So brand search gets reported apart from non-brand, and a holdout test checks from time to time whether it adds clicks or just moves them from organic to paid.
As organic results build, typically over months 3-6 and beyond, paid changes job. It moves toward the queries organic hasn't won, new services and markets, competitor searches, retargeting organic visitors, and testing a topic before a content cluster gets built around it. When organic grows strong enough to win clicks paid was buying, we recommend cutting that spend, and the budget we manage shrinks with it.
Who shouldn't pay for an audit?
Two kinds of account. A small one, with fewer than about 100 relevant clicks a month, doesn't hold enough data for an audit to find much: run the checklist above yourself in an afternoon and put that money into the landing page. And a business that fails the nine checks needs a decision before it needs an audit. Our Google Ads viability check runs the same gates, and it's built to tell you when to keep your money.
We run this audit as the first two weeks of our paid media work. The page publishes what it costs and says who shouldn't buy it.
