The Google Ads audit checklist agencies actually use (40 checks, with thresholds)

A working Google Ads audit checklist for agencies: conversion tracking, wasted spend, bidding, budgets, settings and creative, with pass/fail thresholds.

Most Google Ads audit checklists online are a list of questions. "Is conversion tracking set up?" "Are there negative keywords?" That is a start, but an audit is only useful when every check has a threshold: a line where the answer flips from fine to fix. Otherwise two people audit the same account and reach different conclusions.

This is the checklist we built into Agency Lookout, written out in plain language with the thresholds we use. Use it as-is, or tune the numbers per client (a lead-gen plumber and an ecommerce store should not share the same limits).

A note on order. The checks are grouped by module, and the modules are in the order that matters: if conversion tracking is broken, every later number in the account is unreliable, so fix measurement first.

Module 1: Measurement (fix these before anything else)

Nothing below means anything until these pass.

CheckPasses whenSeverity
Primary conversions are recordingConversions > 0 in any period with spend > 0Critical
A real Primary conversion action existsAt least one enabled action that is Primary and counted in the Conversions column, and it is a lead, purchase or call, not a page viewCritical
No vanity actions set as PrimaryNo page-view, scroll, engagement, YouTube or "micro" actions marked PrimaryHigh
Conversions still arrivingConversions in the last 14 days when the prior 30 had someHigh
All-conversions inflation"All conversions" is less than 3× "Conversions"Medium
Conversion rate is plausibleAccount conversion rate between 0.5% and 40% of clicksHigh
Conversion value is trackedValue > 0 when conversions > 0 (sales accounts)High
No duplicate Primary actionsOne recording Primary action per category (one "lead form", not three)Medium
Auto-tagging enabledauto_tagging_enabled = true on the accountMedium
Primary actions that never fireEvery enabled Primary action records something while others doLow

Why the "plausible conversion rate" check exists: a 60% conversion rate almost always means a page view or a button click is being counted as a conversion. Smart Bidding then optimises toward that, and the account spends real money chasing fake conversions.

Module 2: Search terms and wasted spend

CheckPasses whenSeverity
Base waste poolZero-conversion search-term spend ≤ 15% of all term spend (25% or more is high)Medium
High-confidence waste (negative candidates)No term with zero conversions and ≥ $20 spend, or ≥ 50 clicks, or ≥ 1,000 impressions in 90 daysHigh
Campaigns spending without convertingNon-converting campaigns ≤ 10% of spendHigh

A term with 50 clicks and no conversions is not "still learning". It is a negative keyword waiting to be added. Group the candidates by intent (research, DIY, jobs, competitors, wrong location) before you negate them; it makes the client conversation much shorter.

Module 3: Bidding

CheckPasses whenSeverity
Smart Bidding has enough conversion volume≥ 15 conversions per 30 days per campaign using Target CPA / ROASMedium
Uncapped Smart BiddingMaximize Conversions / Value campaigns with ≥ 20% of spend carry a targetLow

Below 15 conversions a month, Target CPA mostly guesses. Either consolidate campaigns so the data pools, or move to Maximize Conversions with a target.

Module 4: Budget

CheckPasses whenSeverity
Converting campaigns limited by budgetLost impression share (budget) < 10% on campaigns with a CPA at or under targetHigh
Impressions lost to ad rankLost IS (rank) < 40% per campaignMedium
Budget pacingLast-30-day spend is between 70% and 105% of daily budget × 30.4Info

The first one is the easiest money in the account: a campaign that converts at target and is losing 30% of impressions to budget is simply under-funded.

Module 5–7: Structure, landing pages, settings

CheckPasses whenSeverity
Enabled campaigns that aren't servingNo enabled campaign without impressions in 30 daysLow
Spend concentrated on the homepageHomepage takes < 50% of spendMedium
Landing pages spending without convertingNo page with ≥ 2× CPA (min $50) and zero conversionsMedium
Final URL hygienehttps final URLs, no broken tracking templatesMedium
Location targeting"Presence", not "Presence or interest"Medium
Search campaigns kept off Display / Search PartnersDisplay network off on Search campaignsMedium
Device performanceNo device with ≥ 20% of spend and zero conversions, or a CPA over 2× the accountMedium

"Presence or interest" is still the default in many accounts, and it is how a Georgia plumber ends up paying for clicks from someone in Ohio who once searched "Atlanta".

Module 8–9: Creative and policy

CheckPasses whenSeverity
RSA ad strength< 20% of RSA impressions on "Poor"Medium
Ad groups with a single adEvery spending ad group has ≥ 2 enabled adsLow
Sitelink, callout and snippet coverageSitelinks and callouts enabled at account or campaign levelLow
Disapproved or limited adsNo enabled ad disapprovedHigh
Auto-applied recommendationsNo changes made by recommendation auto-apply in the last 30 daysMedium
Automated / third-party writesChanges by API, scripts or rules in the last 30 days are known and authorisedLow

Auto-applied recommendations deserve their own line. Google will, by default, add broad match keywords and raise budgets on your client's behalf. Turn it off, then check the change history to see what it already did.

Search-specific: keywords

CheckPasses whenSeverity
Quality Score (spend-weighted)≥ 7 pass · 5–6.9 medium · < 5 highMedium
Very low Quality Score keywords spendingNo keyword with QS ≤ 3 and ≥ $100 spend in 30 daysHigh
Ad relevance below averageBelow average with ≥ 1,000 impressions → rewrite the ad group's adsMedium
Landing page experience below averageBelow average with ≥ $50 spend → fix the pageMedium
Broad match governanceNon-converting broad match ≤ 20% of keyword spendMedium
Phrase / exact duplicationSame keyword not in both phrase and exact in one campaignLow
Keywords wasting spendNo keyword with zero conversions and ≥ $100 spend or ≥ 100 clicksHigh

Performance Max

CheckPasses whenSeverity
PMax search categories (waste & brand)No zero-conversion search category taking a large share of spend; brand terms excluded where the client wants them in a Search campaignHigh
PMax search-term visibilityYou have pulled the search-category report at all (most people have not)Info

Economics (the one check clients care about)

CheckPasses whenSeverity
Cost per conversion vs break-evenCPA ≤ average job value × close rate × target marginHigh

Everything above is a means to this. A $40 cost per lead is great for a roofer and ruinous for a $25 product. Ask the client for job value and close rate during onboarding, and the audit can say "profitable" or "not" instead of "CPA went up 8%".

How to run this without spending a day per account

Run through the checklist once by hand on your biggest account; you will know your thresholds are right when the "fails" match what the specialist on that account already suspected.

After that, the work is repetition across 10, 20, 40 accounts every month, and that is what software is for. Agency Lookout runs exactly these checks on every connected Google Ads account, ranks the failures by severity and spend, turns each one into a task with the evidence attached, and re-checks it live when the task is marked done. The audit itself is read-only; nothing in the account changes unless a person applies it.

If you only take one thing from this page: write your thresholds down. An audit without thresholds is an opinion.
