Why Do a Google Ads Audit and Who Should Do It?

Un compte Google Ads that has been running for months gives a deceptive sense of security. Campaigns deliver, budget is consumed, a few conversions come in, and everything seems to work. Yet beneath this calm surface, it is not uncommon for a third of the budget to go to worthless clicks, without anyone noticing.

This is precisely what a audit Google Ads reveals: a methodical examination of your account that identifies what is wasting money and what could earn more. Far from being a luxury, it is often the intervention with the best return on investment, as it acts on a budget you are already spending.

Here is why to carry out an audit, what it concretely examines, and who to entrust it to.

Key takeaways from this article

• A Google Ads audit reveals wasted budget and unexploited performance levers.
• It examines the account structure, targeting, ads, bids and conversion tracking.
• Defective conversion tracking is the most frequent and most costly error.
• A good audit concludes with a prioritised action plan, not a simple list of findings.
• It is better to entrust it to an outside perspective — a certified agency or consultant — than to whoever created the account.

Why Carry Out a Google Ads Audit?

The first reason is financial. Google Ads charges for each click, and a poorly configured account multiplies useless clicks: off-topic queries, overly broad audiences, ads served at the wrong time. An audit tracks down these leaks and recovers a budget already committed, making it an investment with an almost immediate effect.

The second reason is strategic. An account evolves through successive additions, at the pace of campaigns and emergencies, until it loses all coherence. The audit takes a step back: it checks that the structure serves your marketing objectives, that the right indicators are tracked, and that nothing is working against you. It is also the best way to identify quick wins, those simple optimisations with high impact.

Definition: Google Ads audit

A Google Ads audit is a structured analysis of an advertising account, designed to evaluate its performance and identify areas for improvement. It covers the campaign structure, targeting, ads, bids, landing pages and conversion tracking, then leads to a prioritised action plan.

What a Google Ads Audit Analyses

A serious audit does not limit itself to looking at the cost per click. It scrutinises the account across several complementary dimensions.

Account Structure

This is the skeleton. The audit checks the organisation in campaigns and ad groups, the coherence between keywords, ads and landing pages, and the absence of overlaps that make your own campaigns compete with each other. A clear structure conditions all performance.

Targeting and Keywords

The analysis covers the relevance of keywords, match types, and above all the search terms report, which reveals the actual queries that triggered your ads. This is where wasted clicks are hiding, often for lack of excluded keywords.

Ads and Landing Pages

An audit evaluates the quality of ads, their click-through rate and relevance, then checks that landing pages deliver on the message promise. An excellent ad that redirects to a slow or off-topic page wastes the paid click.

Conversion Tracking

This is the most critical point, and the most frequently defective. Without conversion tracking that is reliable, the algorithm optimises blindly and your reports lie. The audit checks that each important action is measured correctly, without duplicates or omissions.

Audit Control Points

Who Should Carry Out Your Google Ads Audit?

The question of the provider is as important as the question of method. Three options exist, with very different levels of reliability.

Automated Tools

Many tools offer a free and instant audit. They spot obvious anomalies but remain superficial: they understand neither your market, nor your margins, nor your objectives. Useful as a first signal, they do not replace human analysis and often serve as a commercial lure.

The Person Who Already Manages the Account

Entrusting the audit to whoever built the account poses an objectivity problem. It is difficult to spot one’s own blind spots or to question one’s own choices. An outside perspective brings precisely what the current manager cannot offer: critical distance.

A Certified Agency or Consultant

This is the most reliable option. A Google Ads agency or a certified consultant combines experience across many accounts, up-to-date monitoring and the necessary independence. Check the certification level: Google Partner Premier status, reserved for the top 3% of partners in France, is a mark of seriousness.

What Distinguishes a Good Audit

Not all audits are equal. Here are the markers of genuinely useful work.

• A prioritised action plan: a good audit does not list findings, it ranks actions by impact and effort, from quick wins to long-term projects.
• Quantified recommendations: each identified problem must be linked to an estimated effect on budget or conversions.
• A business reading: the audit starts from your commercial objectives, not just Google Ads’ internal metrics.
• Educational value: a good report explains the why, so that you keep control over decisions.
• No magic promises: be wary of an audit that guarantees quantified results before having acted.

FAQ: The Google Ads Audit

How Much Does a Google Ads Audit Cost?

It varies depending on the size of the account and the depth of the analysis. Some agencies offer a first audit for free as a commercial move, others charge for an in-depth service of a few hundred to a few thousand euros. Above all, compare the content of the deliverable.

How Often Should You Audit Your Account?

A comprehensive audit once or twice a year is a good rhythm, supplemented by monthly monitoring of performance. An audit is also essential after a major change: site redesign, new offer or unexplained drop in results.

Can I Carry Out the Audit Myself?

In part, yes, notably via the search terms report and the control of conversion tracking. But an experienced outside perspective spots blind spots that an internal manager, too close to the account, often misses.

Does an Audit Guarantee Better Performance?

It identifies the levers, but results then depend on their implementation. A serious audit never guarantees a figure: it provides a action plan that is reliable, whose impact is measured after application.

Do You Need to Give Account Access for an Audit?

Yes, read access is generally sufficient. Make sure to remain owner of your account and to grant access via the provider’s identifier, rather than transferring ownership to them. This way you keep control and your history.
