How Much Does a Google Ads Audit Cost?

A Google Ads audit can cost nothing or several thousand dollars, and the price mostly tells you how deep the review goes. Agencies often offer free audits to win management work. Flat-fee settings checks are advertised from a few hundred dollars. My Google Ads audit starts at $3,500, and multi-channel audits that cover Google, Meta, LinkedIn and other platforms start at $5,500. What you are paying for is someone checking whether your conversion data can be trusted, reading what you actually paid for, and handing you a prioritized list of fixes tied to cost per lead or sale.

1. How much does a Google Ads audit cost?

Prices fall into three rough groups. Free audits come from agencies that want to manage your account, so they are short and usually end with a proposal. Low-cost audits, often a few hundred dollars, tend to be a checklist of settings: ad extensions, bid strategies, location targeting. Full audits run into the thousands because they take days of work, including comparing Google's conversion numbers with your CRM or store, reading the search terms report, and looking at how Performance Max spends its budget.

For reference, my Google Ads audit starts at $3,500 for Google Ads alone, and multi-channel audits start at $5,500. Both are flat fees quoted after a free 30-minute call, and the price does not depend on how much you spend on ads.

2. What drives the price of a Google Ads audit?

The biggest factor is how hard the account is to untangle. An account with five search campaigns and one conversion action takes far less time than one with Performance Max, several brands, dozens of campaigns, phone call tracking and offline conversion imports. The second factor is whether the audit checks Google's numbers against your own. Comparing conversions in Google Ads with your CRM, your store or your call records is slow work, and it is where most of the useful findings come from.

The third factor is who does the work. A junior analyst running a template costs less than a senior strategist who can tell you which findings matter for your margins and which can wait. The last factor is the deliverable. A score out of 100 is cheap to produce. A written review with a prioritized list of fixes, and someone to walk you through it, takes longer.

3. What is the difference between a free audit and a paid one?

A free audit is a sales tool. That does not make it useless, but the agency doing it has a clear reason to find problems that its management service would solve. Free audits also rarely include the slow parts, such as reconciling conversions with your CRM or reading months of search terms.

A paid audit should give you something you can act on whether or not you hire the person who wrote it. If an audit cannot be handed to your in-house team or your current agency as a work plan, it was mostly a pitch.

4. What should a Google Ads audit include?

At a minimum, a full audit should cover six areas. Conversion tracking comes first: whether the account counts the actions that make you money, and whether those numbers match your records. Then account structure, including how brand and non-brand search are separated and what Performance Max is buying. Then the search terms you actually paid for, bidding and budget, ads and landing pages, and finally reporting and ownership, starting with whether the account is in your company's name.

The output should be a clear, prioritized list of fixes to reduce waste and improve acquisition cost, plus an assessment of Performance Max and a conversion tracking check so you know which numbers to trust. My Google Ads audit checklist walks through what to look at in more detail.

5. Is a Google Ads audit worth the money?

Run the math on your own account. If you spend $20,000 a month and even 10% of that goes to searches that never turn into customers, that is $2,000 a month, or $24,000 a year. An audit that finds and fixes that waste pays for itself several times over. If you spend $3,000 a month, the same 10% is $3,600 a year, and a $3,500 audit is harder to justify.

The other way an audit pays off is by fixing tracking. When conversion data is wrong, smart bidding optimizes toward the wrong thing, and every budget decision built on those numbers is off. That cost does not show up as a line item, which is why it tends to run for months before anyone notices.

6. When should you skip the audit?

If your monthly spend is small, start with a self-check instead. My free Google Ads Efficiency Scorecard has 30 questions, takes about 30 minutes with the account open, and shows which areas to look at first. If you already know you are replacing your agency, an audit is still useful, but treat it as the brief for whoever takes over the account.

7. How do I get started?

Score your account with the scorecard, or bring your questions to a free 30-minute call. If an audit makes sense, I will quote a flat fee for your account. If it does not, I will tell you that too.
