Google Ads Audit Checklist: The Complete 2026 Guide (+ Free AI Audit)

A Google Ads audit is a structured review of an account to find what’s wasting budget, what’s mis-measured, and what’s left on the table. Run it quarterly, before taking over an account, or any time performance drifts without an obvious cause.

This is the complete checklist, ordered the way an experienced PPC manager actually works it: measurement first (because every other number is wrong if tracking is broken), then structure, spend, and optimization. Copy it, work top to bottom, and you’ll catch the issues that account for most wasted spend.

1. Conversion tracking — audit this first

If conversion tracking is wrong, every other metric in the account is fiction. Start here, always.

• ✅ Every primary conversion action has recorded conversions in the last 7 days (no “no recent conversions” warnings)
• ✅ Exactly one primary conversion per goal — no duplicate tags double-counting
• ✅ Conversion values are passed (not blank) where revenue matters
• ✅ Attribution model is intentional (data-driven is the 2026 default) — not left on last-click by accident
• ✅ Enhanced Conversions is on if you have first-party data
• ✅ No “click-through only” conversions silently inflating thin-funnel actions

2. Account structure

• ✅ Campaigns are segmented by intent and margin, not by a structure inherited from 2019
• ✅ Search and PMax aren’t cannibalizing each other on the same queries
• ✅ Ad groups are tight enough that one set of ads matches the keywords
• ✅ Brand and non-brand are separated (so you can read true non-brand performance)

3. Wasted spend

• ✅ Search-terms report reviewed — irrelevant queries with spend and zero conversions
• ✅ Negative-keyword lists exist and are applied at the right level
• ✅ No overlap between Search and Shopping/PMax burning the same term twice
• ✅ Geographic and device performance checked for spend with no return
• ✅ Display/Search partner placements reviewed for junk traffic

4. Keywords & match types

• ✅ Match-type mix is intentional (broad only paired with Smart Bidding + tight negatives)
• ✅ Low-quality, zero-conversion keywords identified for pausing
• ✅ Search-term mining is a recurring habit, not a one-time cleanup

5. Ad copy & assets

• ✅ Every ad group has at least 2 responsive search ads
• ✅ Ad strength is “Good” or “Excellent” where it affects eligibility
• ✅ Sitelinks, callouts, structured snippets, images, and other assets are present
• ✅ Copy reflects current offers — not last quarter’s promotion

6. Bidding & budgets

• ✅ Bid strategy matches the goal (tCPA/tROAS only with enough conversion volume)
• ✅ Targets are realistic — not a tROAS so high the campaign can’t spend
• ✅ Budget-limited campaigns with strong ROAS identified for more budget
• ✅ Shared budgets aren’t starving your best campaigns

7. Performance Max

• ✅ Asset groups segmented by theme, each with full assets and a “Good”+ strength
• ✅ Search-themes and audience signals are set (not empty)
• ✅ Brand exclusions applied so PMax isn’t claiming cheap brand conversions
• ✅ Account-level negatives applied to PMax where supported

8. Audiences & remarketing

• ✅ Remarketing lists are active, populated, and above size thresholds
• ✅ Customer Match lists uploaded and refreshed if you have the data
• ✅ Audience signals feeding Smart Bidding, observation where you want data
