The Complete Google Ads Audit Checklist (2026): 12 Sections, Yes-or-No Checks

Google advertising brought in $82.3 billion in just the last quarter of 2025, up 14 percent from the year before. That is the number in Alphabet's own filing. More money is flowing through Google Ads every quarter. So is more waste. When clicks cost more, a leaky account bleeds faster. This checklist exists so no leak hides. It is the corrective to the audit advice already ranking for this search.

Why the current checklists fail you

Search "google ads audit checklist" and look at what ranks. The picture is not good.

One is a guide from 2024. It is the most useful of the bunch. But it is almost 2 years old. It came out before the 2025 Performance Max (PMax, Google's automated campaign type) changes, before the Demand Gen updates, and before the latest tracking shifts. Another is a short, general checklist. It lists the steps but never says what each one is worth or how to fix it. The other two are sales pages. One is a paid agency audit. One is a free tool that wants your email first. Both are pitches, not checklists.

Here is what none of them do. None of them publish the dollar cost of getting each check wrong. None of them link to the method that actually fixes each problem. So you run their list. You find a few "you should check this" items. You still do not know what is at stake or what to fix.

How to use this checklist

The checklist works one of three ways.

Run it in one sitting. Block 3 to 4 hours. Open your Google Ads account. Walk the 12 sections in order. Mark each one yes or no. Next to every "no," write the leak in a notes app. At the end you have a list and a fix order.

Run it as a monthly check. Set a repeat for the first Monday of each month. Walk only the sections that drift fast: 1 (tracking), 2 (attribution), 8 (budget), and 9 (negatives). The rest only need a look once a quarter.

Hand part of it to a junior. A junior can run sections 4, 5, 7, and 9 without help. Those are pattern checks, not judgment calls. A senior runs the rest.

The interactive version of this checklist saves your progress in the browser, so you can pause and pick it back up. There is also a printable PDF with the dollar impact on every line.

Section 1: Conversion tracking integrity

The check: Do your conversion actions fire on the right events, like a real Purchase or a qualified Lead, with the right value attached?

Dollar impact: Broken tracking poisons every other signal in this audit. At $20K monthly spend, this one issue misroutes about $3,000 to $7,000 a month.

Fix order: 1) Check that events fire in your Google Ads conversion settings. 2) Cross-check against Shopify or your CRM (customer relationship management tool, where you store leads and sales). 3) Reconcile the last 7 days of conversions across both.

This is stage 1 of the full Google Ads audit method. If tracking fails, stop here and fix it before you grade anything else.

Section 2: Cross-platform attribution

The check: Do your Google-reported conversions, plus your Meta-reported conversions, add up to within 25 percent of your real Shopify orders?

Dollar impact: A gap over 25 percent means you are scaling on inflated numbers. At $20K spend, that misroutes about $4,000 to $8,000 a month.

Fix order: 1) Pull the last 30 days of conversions from each platform. 2) Compare to Shopify orders. 3) If the gap is over 25 percent, check for double-counting and long view-through windows.

This is the most common hidden leak. The full breakdown is in why your ad reports show 3 different numbers. Use the Attribution Reconciliation Calculator to do the math fast.

Section 3: Account-level Quality Score

The check: Quality Score (QS) is Google's 1-to-10 rating of how relevant your ad and landing page are. Is your account-wide weighted QS above 6, with no high-spend campaign below 5?

Dollar impact: Each point of QS gain cuts your cost per click (CPC) by roughly 10 to 15 percent. A 2-point lift across the account means about 20 percent more efficient spend. That is $4,000 a month at $20K spend.

Fix order: 1) Pull QS by campaign. 2) Flag any campaign below 6 that takes more than 10 percent of spend. 3) Lift it in this order: Expected click-through rate, then Ad Relevance, then Landing Page Experience.

Google's own Quality Score documentation explains that a higher score means your ad and page are more useful to the searcher than rival ads. More useful ads win better spots for less. The deep dive is in Quality Score: what it actually measures.

Section 4: Self-Defense Campaign

The check: A Self-Defense Campaign bids on your own brand name. Three metrics grade it. Search Impression Share (SIS) is the share of brand searches where your ad showed. Is your campaign running with SIS above 95 percent, Top Impression Share (TIS) above 90 percent, and Absolute Top Percentage (ATP) above 80 percent?

Dollar impact: No brand defense lets rivals grab 15 to 30 percent of people searching your name. At $20K total spend, that gap costs about $2,000 to $6,000 a month in lost sales.

Fix order: 1) Search your brand name in a private window on phone and desktop. 2) Check SIS, TIS, and ATP in Google Ads. 3) If no campaign is running, launch one with exact-match keywords and manual CPC.

The full case is in the Self-Defense Campaign method.

Section 5: Match-type discipline

The check: Are your exact, phrase, and broad match keywords in separate campaigns, with the bidding strategy matched to each match type?

Dollar impact: Match-type bleed (broad match with no smart bidding or too little data) wastes 20 to 35 percent of non-brand spend. At $20K spend with 60 percent going to non-brand, that is $2,400 to $4,200 a month gone.

Fix order: 1) Pull the Search Terms Report for the last 30 days. 2) Flag campaigns that mix match types or run broad match without enough conversion data. 3) Split them apart.

The framework is in the Match-Type Discipline guide.

Section 6: Bidding strategy fit

The check: Does each campaign's bidding strategy match its data depth? Manual CPC under 10 conversions a month. Maximize Conversion Value above 30 conversions a month.

Dollar impact: Smart bidding on a data-starved campaign wastes 15 to 25 percent of spend on noise. At $20K spend, that is $3,000 to $5,000 a month of bad bets.

Fix order: 1) Pull conversion volume per campaign for the last 30 days. 2) Flag any campaign below its strategy's minimum. 3) Switch it to manual until the volume builds.

The full test is in the Smart Bidding audit.

Section 7: Performance Max placement

The check: Does your Performance Max (PMax) campaign spend 60 percent or more on Search and Shopping, with Display plus YouTube under 30 percent combined?

Dollar impact: PMax that overspends on Display and YouTube wastes 30 to 50 percent of its budget on low-intent placements. At $10K PMax spend, that is $3,000 to $5,000 a month.

Fix order: 1) Open the PMax campaign, then Insights, then the placement breakdown. 2) If Display plus YouTube is over 30 percent, rework the asset groups or split the campaign. 3) Re-check monthly.

The full audit is in the Performance Max audit checklist.

Section 8: Budget allocation by stage

The check: Does your budget split match your account stage? The 4 stages are Launch, Optimization, Scaling, and Cost-Cut.

Dollar impact: Budget set for the wrong stage wastes 20 to 30 percent of total spend. At $20K spend, that is $4,000 to $6,000 a month.

Fix order: 1) Name your stage. 2) Set the budget split for that stage. 3) Re-check every quarter.

The 4 stages are explained in the 4 stages of an account guide. The stages are written for Meta, but they work the same way on Google.

Section 9: Negative keyword hygiene

The check: Does each campaign have at least 50 negative keywords blocking off-intent search terms?

Dollar impact: Missing negatives waste 10 to 20 percent of search spend on the wrong traffic. At $12K of search spend, that is $1,200 to $2,400 a month.

Fix order: 1) Pull the Search Terms Report. 2) Add as a negative any term that got 5 or more clicks with zero conversions. 3) Repeat monthly.

This one is fast and it pays back every month. It is the easiest "no" to turn into a "yes."

Section 10: Mobile landing page speed

The check: Largest Contentful Paint (LCP) is the time for the main content to load. Does Google PageSpeed Insights show LCP under 2.5 seconds on mobile for your top landing page?

Dollar impact: Slow mobile LCP costs 5 to 15 percent of mobile conversions. At $20K spend with 70 percent mobile traffic, that is $1,500 to $4,500 a month in lost sales.

Fix order: 1) Run PageSpeed Insights on your top 3 landing pages. 2) If LCP is over 2.5 seconds, look at images, third-party scripts, and font loading first. 3) Ship the fixes.

The full breakdown is in mobile page speed: the hidden killer of DTC ad ROI. DTC means direct-to-consumer.

Section 11: Checkout flow integrity

The check: Does your mobile checkout pass the test-card walkthrough? Shipping cost shows before checkout, Apple Pay and Google Pay are on, and the form has fewer than 8 fields.

Dollar impact: A broken checkout costs 20 to 40 percent of completed-cart sales. At $20K Google spend, that is $4,000 to $10,000 a month in reachable revenue.

Fix order: 1) Run a test-card walkthrough on your phone in a private window. 2) Match what you find against the 5 most common patterns. 3) Ship the fixes.

Sarah, a fashion brand owner who runs $40K a month, found her mobile form had 11 fields. Cutting it to 6 lifted her checkout completion in a week. The full method is in the mobile-first checkout audit and the patterns are in the 5 cart abandonment patterns.

Section 12: Unit economics

The check: Look at your current CPC, conversion rate, and average order value (AOV). Is your break-even return on ad spend (ROAS) supported by your gross margin?

Dollar impact: Brands that scale at a break-even ROAS the margin cannot support often find out only after 3 to 6 months. The cost is 100 percent of the extra spend during that window.

Fix order: 1) Work out your true break-even ROAS. 2) Compare it to your current account ROAS. 3) If the account is below break-even, the fix is not more spend. It is structural: margin, AOV, or conversion rate optimization (CRO).

Use the Break-Even ROAS Calculator and read what is a good ROAS for e-commerce.

The dollar impact of each section

Here is the cost of getting each section wrong, at $20K monthly spend. No other checklist on this search publishes this.

These are ranges, not promises. Your account will land somewhere inside them based on your spend and your gaps. The point is simple. Each "no" has a price tag. Most accounts have 2 to 5 of them.

The 12-section checklist

Print this or screenshot it. Walk it top to bottom. Mark each box. Or use the interactive version that saves your progress.

Scoring your account

Count your "yes" boxes out of 12.

The score is not the point. The list of "no" boxes is the point. A short list that includes section 1 (tracking) is worse than a long list that does not. Fix in this order, no matter where your leaks sit: section 1 first, then 2, then 8, then everything else. Bad tracking makes every other finding a finding about fiction.

If you run both Google and Meta, the same logic applies on the other side. See the complete Facebook Ads audit checklist for the Meta version of this list. The full method behind every section here lives in the Google Ads audit method.
