Google Ads checklist: 25 checks to find wasted spend

Start with trustworthy conversions, then check targeting, budgets and the customer journey. Use these 25 checks to turn an account review into a clear action plan.

A useful Google Ads checklist answers three questions: are you measuring real outcomes, are you buying the right visits, and can those visitors become customers? Start there before rewriting every ad or changing your bid strategy. This guide focuses on Search campaigns; Shopping and Performance Max need additional feed, asset and channel checks.

Use a recent period that covers your normal sales cycle, plus a comparable previous period. Record campaign changes, promotions and tracking outages. An incomplete week of sales should not be compared with a fully matured month.

For query-level decisions, use the negative keyword checklist. If this review is part of changing suppliers, also complete the agency handover checklist.

Example: turn an audit finding into a decision

This is an illustrative workflow, not a client result. Suppose a form-button click is marked as the main conversion even when validation fails. Test an invalid and a successful submission, save the event sequence, and assign the tracking owner to trigger the outcome on confirmed success. Retest before changing campaign goals.

Do not exclude a promising query solely because a very small sample has no sales. Agree a review window and budget limit before running the test.

Before you start: collect evidence

Open Google Ads, your tag-testing tool, GA4 and your sales or order records. Save a baseline of spend, clicks, CPC, meaningful conversions, cost per conversion and resulting sales. For leads, include qualification and close rates. For ecommerce, include cancellations and returns in your commercial review.

The 25 checks below are grouped by the decision they help you make. Mark each pass, fail or investigate; attach the report or test that supports that label. A missing answer is an investigation task, not proof that a campaign is broken.

Checks 1–5: conversions you can trust

• 1. Business outcome: identify the action each campaign should optimise for: a purchase, accepted enquiry, booking or another clearly defined outcome.
• 2. Primary goals: inspect both account and campaign goals. Keep diagnostic actions such as scrolling out of acquisition bidding unless they deliberately serve that campaign’s objective.
• 3. Duplicate signals: check whether a native Google Ads tag and an imported GA4 event both count the same outcome as primary.
• 4. Real journey: submit a valid enquiry or test order, then test a failed submission and a refresh. Confirm the outcome is recorded only when it actually succeeds.
• 5. Commercial feedback: reconcile a sample with CRM or order records. Check spam, qualified opportunities, cancellations, values and currency.

Google’s primary and secondary conversion guidance explains which actions can influence bidding. Check custom goals too: they can use secondary actions for bidding. If the measurement itself is uncertain, work through the GA4 audit checklist first.

Checks 6–10: the demand you are buying

• 6. Actual queries: review search terms by spend and outcome, including the keyword that matched them. A keyword list alone cannot show what people searched.
• 7. Exclusions: add negatives for demonstrably irrelevant intent, such as job searches when recruiting is not your offer. Check that exclusions do not block genuine customers.
• 8. Brand separation: compare brand and non-brand results separately so existing demand does not conceal weak prospecting.
• 9. Geography and language: compare targeted settings with actual customer locations and the languages your page and team can support.
• 10. Networks and devices: inspect segments for differences in qualified outcomes before deciding to exclude them.

The search terms report is a useful diagnostic view, but it does not expose every search. Do not interpret a clean visible list as proof that all traffic is relevant. In Latvia, review Latvian, Russian and English queries separately where those languages are part of the campaign.

Checks 11–15: the experience after the click

• 11. Promise match: the landing page should explain the offer the ad actually promised.
• 12. Mobile completion: use a real phone to test navigation, fields, validation, payment and the confirmation step.
• 13. Clear next action: make it obvious whether the visitor should buy, request a quote, call or book.
• 14. Friction and qualification: remove unnecessary fields while retaining information needed to assess fit or fulfil an order.
• 15. Follow-up: verify that an enquiry reaches the right person and that calls or bookings can be handled during the advertised hours.

A working submit button is not enough. Follow the submission into the system your team uses. Our landing-page guide helps separate offer, usability and form problems.

Checks 16–20: bidding and budget

• 16. Objective fit: confirm the bidding strategy matches the goal. Buying clicks and optimising for customer actions are different jobs.
• 17. Target realism: compare CPA or ROAS targets with mature, reliable history and your business economics.
• 18. Budget concentration: check whether too many small campaigns are competing for a limited learning budget.
• 19. Spend control: check pacing, campaign limits and shared budgets against the amount you approved.
• 20. Change history: annotate major edits, then allow for reporting and conversion delays before judging them.

For most campaigns, an average daily budget is not a hard daily spending cap. Google explains the relevant limits in its spend-management guidance. Build a CPC strategy around affordable customer acquisition, rather than a universal cheap-click target.

Checks 21–25: decisions that improve the business

• 21. Lead ownership: record who receives each enquiry and who follows up if the first owner is unavailable.
• 22. Quality definitions: agree what makes a lead qualified, rejected or won, and record reasons consistently.
• 23. Revenue meaning: distinguish order revenue, open pipeline and collected revenue. Use the same definition when comparing campaigns.
• 24. Cohort maturity: assess older clicks after their sales cycle has had time to complete; do not treat recent open leads as lost deals.
• 25. Action log: give every proposed change a reason, owner, review date and success measure.

In a Reddit discussion about account audits, contributors describe starting with tracking and whether the campaign measures the right business action. That is practitioner experience, not a controlled study. Use it as a prompt to inspect your own evidence rather than copy someone else’s bids or account structure.

Turn findings into a short action plan

Fix broken measurement and broken customer journeys first. Then address clear waste. Keep broader bidding or structure changes as separate experiments so you can tell which change helped.

Common questions

How often should I run this checklist?

Check delivery, tracking failures and obvious waste regularly. Run a deeper audit after a migration, a major account change or an unexplained performance shift. Set the routine around spend, conversion volume and sales-cycle length.

Should I implement every recommendation in Google Ads?

Assess each against your objective and evidence. A recommendation or optimisation score is not a substitute for customer profitability.

Does a lower CPC mean better performance?

Only if the resulting traffic still converts economically. Compare cost per qualified lead or customer alongside CPC, using equivalent conversion windows.

After the audit, use our weekly and monthly management checklist to turn findings into a repeatable routine.

Score priorities without inventing precision

A Google Ads audit is a structured review of measurement, targeting, spending and the customer journey. Its output should be a short list of justified changes, each with evidence, an owner and a retest date.

Download the 25-check audit worksheet. Mark each check pass, fail or investigate and attach the relevant test or report. Use the following working rubric; it is our organisational template, not a Google score or a profitability model.

For non-critical findings, sort by impact × evidence ÷ effort to discuss the order of work. A confirmed broken form overrides that calculation: repair and retest it first. An unknown answer belongs in investigation; do not label it a verified failure to improve its score.

Worked priority example

Suppose a valid form fails on mobile: impact 3, evidence 3, effort 1 gives a discussion score of 9. A proposed campaign restructure with impact 2, evidence 1 and effort 3 gives 0.67. Fix the form before restructuring. These are illustrative scores, not expected financial returns.

After each approved fix, record what changed and whether the original problem disappeared. Assess business outcomes over a comparable period and account for conversion delay. A higher optimisation score alone does not prove more customers.

Keep an audit finding reproducible

An audit record should let another person repeat the check. Record the page or campaign, device, consent state, test steps, expected result, actual result and evidence date. For a form, test an invalid submission, an accepted submission, a server error and a reload. The success event should follow confirmed acceptance, not merely a button click; check duplicate submissions as well.

On this website, the main audit form separates validation and step-continuation events from generate_lead; its production success event follows an accepted server response. GA4 loading and event transmission require analytics consent. This is an implementation example, not a claim of measured conversion lift or proof that every production lead reached the inbox. The corresponding audit must also verify storage, delivery and sales follow-up.

Compare measured acquisition cost with the break-even calculator. A cheaper click can still be unprofitable when fulfilment and acquisition costs are included.
