What should a Google Ads audit actually check?

Start with measurement. Then review search demand and targeting, campaign structure, ads and landing pages, bidding and budgets, and finally lead quality or revenue outcomes. An audit cannot reliably diagnose performance when the conversion data it relies on is wrong.

A useful audit should answer five questions:

  • Are the primary conversion actions genuine business enquiries?
  • Are the campaigns paying for searches, people and locations that plausibly match the offer?
  • Can the account show which campaign, query and landing page created each meaningful outcome?
  • Are budget and bidding decisions being made from enough clean data?
  • Do the leads become contacts, quotes, bookings or customers at an acceptable cost?

This is different from checking whether the interface contains warnings. A Google recommendation may deserve attention, but it is not automatically the highest-priority action for that business.

Key insight

Audit the measurement before the optimisation. If the account’s definition of a conversion is misleading, every downstream efficiency claim may also be misleading.

Google’s optimisation score is not the same as account profitability

Google describes optimisation score as an estimate of how well an account is set to perform. It is calculated from account and campaign statistics, settings, status, available recommendations and recent recommendation history. Applying or dismissing a recommendation changes the score.

That makes the score useful for discovering ideas and account conditions. It does not make 100% the commercial objective. Each recommendation should be evaluated against the campaign goal, conversion definitions, available evidence and business economics. A suggestion to expand reach may be sensible in one well-measured campaign and premature in another that is already attracting weak enquiries.

Quality Score is a separate diagnostic. Google explicitly says the 1–10 keyword-level score is not a key performance indicator and is not an input in the ad auction. Its components-expected click-through rate, ad relevance and landing-page experience-can help locate areas worth improving. The displayed score should not be aggregated into a substitute for qualified leads, sales or profit.

Rule

A healthy-looking account is not enough. The audit must connect platform behaviour to qualified demand and commercial outcomes.

A practical Google Ads audit framework for service businesses

1. Verify conversion tracking and definitions

List every conversion action used for reporting or bidding. Test the journey on desktop and mobile, then establish what each action actually represents.

Check for:

  • forms that fire only after a successful submission rather than on button clicks or page views;
  • calls with an appropriate duration or outcome threshold instead of every tap on a phone number;
  • booking events recorded on confirmation, not when the calendar opens;
  • duplicate tags, imported goals or multiple actions counting the same enquiry;
  • low-value micro-actions incorrectly included as primary conversions; and
  • offline or CRM outcomes that distinguish a qualified lead, quote, booking and customer where the sales process allows it.

Record which conversions are primary for bidding and which are secondary observations. If several actions have different commercial values, do not let a high volume of easy micro-conversions hide the absence of serious enquiries.

2. Inspect search demand, matching and targeting

Review the Search terms report, not only the keyword list. Group spend by commercial relevance, service, geography and intent. Look for queries that could not plausibly become the work the business wants.

Negative keywords should come from evidence. Use exact negatives for specific irrelevant queries and phrase negatives for clearly irrelevant intent patterns. Broad negative keywords can block more than expected, so they should not be added casually. Also review existing negatives for over-blocking useful searches.

Check location targeting against the real service area, along with schedules, devices, audiences and network settings. For automated or expansive matching, confirm the account has reliable conversions and a bidding strategy capable of learning from the right signal. Greater reach is useful only when the inputs tell the system what a worthwhile outcome looks like.

3. Review campaign structure, ads and landing pages

Campaigns should separate decisions that need separate budgets, targeting, conversion goals or reporting. Ad groups should represent coherent search intent, not arbitrary bundles of loosely connected services.

For each important query group, check whether the ad and landing page form one continuous promise:

  • the ad identifies the service and relevant differentiator;
  • assets add useful routes, details or proof rather than repeating the headline;
  • the landing page answers the need implied by the search;
  • the business identity and service area are clear;
  • the next action works on mobile; and
  • calls, forms or booking paths feed a process that can respond and record the outcome.

Poor performance is not always a keyword problem. If the page is generic, slow or unconvincing, lowering bids may reduce spend without resolving why qualified visitors fail to enquire.

4. Review bidding, budgets and constraints

Compare budget, bidding strategy, search volume, CPC, conversion rate and cost per meaningful lead. Determine whether a campaign is genuinely limited by budget or whether it simply lacks enough relevant demand, credible ads, a suitable landing page or trustworthy conversions.

Do not change several major controls at once unless the situation requires an immediate stop. A bidding change, new match strategy, rewritten ads and new landing page launched together make it difficult to know what caused the result. Prioritise the dependency, record the baseline and give the selected intervention an appropriate evaluation window.

5. Connect platform conversions to business outcomes

Sample the leads. Were they contactable? Did they need the promoted service? Were they in the target geography? Did the team respond? Did they become quotes, bookings or revenue?

This final layer often changes the diagnosis. A campaign with a higher platform cost per lead may produce more suitable customers, while a low reported CPL may be inflated by spam, duplicates or low-intent contacts. When the account and CRM cannot be reconciled, measurement improvement may be more valuable than another round of keyword edits.

A settings audit vs a commercial Google Ads audit

DimensionWeak / common approachStronger approach
Conversion trackingCheck whether tags fireConfirm tracked actions represent real enquiries and connect to lead quality
RecommendationsApply changes to raise optimisation scoreTest each recommendation against campaign objectives and economics
Search trafficCheck the keyword listReview actual search terms, geography and commercial intent
Bidding and budgetAssume limited budget is the root problemFind whether measurement, demand, conversion or budget is the binding constraint
ReportingPresent clicks, conversions and CPLReconcile paid traffic with qualified leads, bookings and revenue

A long checklist can still be a weak audit when every issue receives the same weight. A broken primary conversion can invalidate bidding and reporting; a missing label or cosmetic naming inconsistency may have almost no immediate commercial effect. Severity, dependency and reversibility should shape the action plan.

What should you fix first after a Google Ads audit?

Use this priority order:

Stop decisions based on false data. Repair broken or duplicated tracking and clarify primary conversion actions.

Contain obvious waste. Pause clearly irrelevant demand or unsafe routing while preserving evidence for a more considered restructure.

Correct intent and destination. Align keywords, search terms, ads and landing pages around the service and customer need.

Improve the commercial signal. Import or record qualified lead and sales outcomes where feasible.

Test the remaining constraint. Adjust bidding, budget or reach after the earlier layers are trustworthy, then measure the result against a baseline.

Digitum’s Google Ads service is built around buyer intent, relevant landing paths and tracking paid traffic through to real outcomes. If the audit needs an independent review, the free health-check conversation can focus on the most consequential measurement, traffic and account issues. The related guides explain Google Ads costs in the UK and how to evaluate competitor keyword bidding.

A useful Google Ads audit does not produce the longest checklist. It identifies the few problems that make the account’s data or commercial decisions unreliable, fixes them in the right order and creates a clean basis for the next test.
