Google Ads audit checklist: find the gaps before you scale

Quick answer

A structured Google Ads audit starts by checking whether conversions are accurate, whether paid queries match the offer and whether landing pages turn useful visits into qualified enquiries or purchases. This checklist helps identify common gaps; the time needed to verify them depends on the account, tracking setup and available data.

What a Google Ads audit actually covers

An audit is a systematic review of tracking, search intent, account structure, ad assets, landing pages and customer outcomes. Changing bids without understanding those foundations can make a reporting problem look like a campaign problem.

Use Google’s conversion tracking guidance to check the platform requirements alongside your actual customer journey.

The Google Ads audit checklist

Use each item as a question to investigate. A tick means the evidence has been reviewed, not merely that a setting exists.

Tracking and measurement

• Analytics is collecting the information needed for the agreed measurement plan.
• Conversion actions represent real forms, calls, purchases or qualified outcomes.
• Primary actions align with the business goal rather than low-value page views.
• Enhanced conversions are considered where relevant, with suitable data handling and configuration.
• Ecommerce values and currencies are checked; lead values are defined as estimates where applicable.
• Calls are measured appropriately when they contribute to sales.
• Duplicate events, test enquiries and imported actions are reviewed.

Search terms and wasted spend

• Search terms are reviewed on a schedule appropriate to account volume.
• Negative keywords remove irrelevant intent without blocking useful demand.
• High-spend queries are compared with conversion quality and sales outcomes.
• Match types and bidding are chosen deliberately and tested with suitable guardrails.
• Location targeting matches the customers and areas the business can serve.

Keywords and account structure

• Ad groups have coherent intent rather than unrelated keyword collections.
• Exact, phrase and broad match are evaluated in the context of targeting, bidding and data quality.
• Overlapping keywords and campaigns are reviewed for unnecessary complexity and routing problems.
• Research-stage and high-intent traffic have a clear purpose and measurement plan.

Keyword overlap does not automatically mean your keywords bid against one another to increase your cost. Investigate how the account selects eligible keywords and whether the structure makes management and reporting harder.

Ads and assets

• Responsive search ads have relevant, varied headlines and descriptions.
• The offer and messaging match the customer’s query and landing page.
• Sitelinks, callouts and structured snippets are accurate where used.
• Additional ads or experiments test a meaningful hypothesis.
• Claims, promotions and assets match what the business can deliver.

Avoid treating a fixed number of ads as a universal optimisation rule. Review the platform’s responsive search ad guidance and account-specific evidence.

Landing pages and conversion

• The page answers the intent behind the ad.
• The main action is visible and understandable on mobile.
• Reviews, case studies and credentials are genuine and relevant.
• Forms work, ask for proportionate information and have clear next steps.
• Mobile loading and interaction are checked on real devices.
• Privacy choices and tracking behaviour are reviewed for the intended market.

For UK-specific privacy information, consult the ICO’s guidance. The appropriate implementation depends on your actual data collection and tools.

Lead quality and sales follow-up

• Leads can be connected to useful outcomes such as qualified, booked, won or lost.
• The team has a response-time target that it can realistically meet.
• Low-quality enquiries are reviewed by query, campaign and landing page where data permits.
• Exclusions and audience settings are appropriate, available for the campaign type and consistent with platform policies.

Common reasons Google Ads underperforms

Incorrect conversion tracking can train optimisation around the wrong action. Intent mismatch can bring visitors who never wanted the service. Unclear pages, weak offers, incomplete follow-up and fragmented budgets can also limit performance.

Check the customer journey before deciding that bidding is the sole cause. Our Google and Meta Ads service connects campaign review with landing pages and measurement.

A practical seven-day review sequence

The sequence is a planning example, not a promise of improvement in seven days. Some changes need development work or a longer observation period. Device bid adjustments and other controls also behave differently under different bidding strategies.

Ten questions to ask a PPC agency

1. Which conversions would you optimise for?
2. How would you verify their accuracy?
3. How would you review search terms and negatives?
4. What account structure would you use and why?
5. Who would improve landing pages?
6. What would the report show beyond clicks?
7. How would lead quality feed back into decisions?
8. Who would own the ad account and data?
9. How would messaging tests be designed?
10. Which findings would justify more budget?

Red flags

Be cautious when a provider guarantees results, cannot explain conversion measurement, ignores landing pages or reports activity without discussing customer quality. Clarify scope before assuming that every PPC engagement includes development or creative production.

Frequently asked questions

How often should I audit Google Ads?

Use regular operational checks for queries, spend and conversions, with deeper reviews when the account changes or results need investigation. The appropriate cadence depends on scale and risk.

Is Smart Bidding suitable in 2026?

It can be useful when conversion definitions, values and campaign goals are appropriate. Evaluate the strategy against your account and recognise that inaccurate inputs can lead to poor optimisation decisions.

Should I run Search or Performance Max?

Choose based on objectives, assets, feed quality, tracking and control requirements. Search can help investigate explicit query intent; Performance Max may suit some cross-channel and ecommerce goals. Test with clear evaluation criteria.

What is the difference between ROAS and ROI?

ROAS is attributed revenue divided by advertising spend. A profit-based marketing ROI calculation subtracts marketing investment from the gross profit attributable to that activity, then divides by marketing investment. State your costs, margins and attribution assumptions.
