Free vs Paid Google Ads Audit: Which Is Better?

Quick answer

A paid Google Ads audit is generally the better choice if you want an independent assessment of your account and your current provider’s performance, provided the auditor is being paid for the review itself rather than relying on selling follow-up services. A free audit can still be useful, particularly if your budget is tight, but it is often part of an agency’s sales process and some ‘bad incentives’ typically exist (in terms of trying to make the account being audited look as badly as possible to support changing provider or purchasing subsequent services). I offer paid audits because I want to be able to recommend whatever the evidence supports - including staying with your existing provider.

If you’re thinking about getting a Google Ads audit, you’ve probably noticed there’s no shortage of free options. I wrote about this recently in my article on how much Google Ads audits cost.

Agencies, freelancers and Google Ads specialists will happily offer to take a look at your account without charging you.

On the other hand, some digital marketing consultants like me charge for Google Ads audits.

Which raises a perfectly reasonable question: why would you pay for something you can get for free?

I’m obviously biased here. I sell paid audits, so you wouldn’t expect me to tell you they’re a complete waste of money. But I also don’t think a paid audit is automatically the right choice for every business.

The main difference comes down to the purpose of the audit, and how the person doing it expects to get paid … as well as your ability to understand the impact of “incentives”.

What are the advantages of a free Google Ads audit?

The biggest advantage is fairly obvious: it’s free. The proverbial free lunch does often exist.

If your Google Ads account isn’t performing well and money is tight - possibly because the ads aren’t performing well - then I think it’s perfectly reasonable to pursue a free audit.

You might get a useful second opinion without having to find more money at an already difficult time.

A competent person reviewing your account could spot configuration errors, wasted spend or mistakes that you or your current provider have missed. You may come away with something straightforward to correct.

I wouldn’t dismiss that just because no money has changed hands.

However, you do need to understand why the audit is being offered for free. In my experience (as a digital marketing consultant I do a lot of work with businesses who have been burned with things like aggressively-pitched free audits

What’s the catch with a free Google Ads audit?

This is where the “no such thing” part of the “no such thing as a free lunch” comes in.

In my experience, most free Google Ads audits are agency/freelancer sales tools.

Think of them as a loss leader. The agency or freelancer invests some time in reviewing your account, demonstrates a bit of expertise, and hopes you’ll sign up for ongoing management.

You get some free insight. They get an opportunity to win your business.

There’s nothing inherently wrong with that arrangement. The problem comes when the need to make a sale starts shaping the findings:

Small problems can become big sales arguments

One pattern I’ve seen is that every issue gets presented as a major problem, regardless of how much it actually matters.

Something that could be corrected in five minutes becomes evidence that your current agency doesn’t know what it’s doing. A setting that deserves a discussion becomes an urgent reason to jump ship.

Something as utterly meaningless as how a campaign is named is made out to be evidence that the account isn’t optimally-structured or run to a good standard (I have literally seen an agency claiming that inconsistent naming structure due to different capitalization and grammar in campaign and ad group names is reflective of “poor management and optimisation practices”)

Funnily enough, of course, the business providing the free audit is also the one perfectly placed to rescue you.

The issue they’ve identified might be real. But that doesn’t necessarily mean it has a material effect on performance, or that changing providers is the appropriate response.

A useful audit should help you understand those distinctions.

There may be limited time spent on your account

From my past agency experience, free audits can also become a volume exercise.

If you’re providing lots of free reviews, and only some turn into paying clients, there’s a commercial limit to how much time you can spend on each one.

That can encourage a quick checklist approach rather than a detailed investigation into what the business needs and how the account is performing.

I’ve also seen free audits that appear to be largely or entirely automated, including AI-generated reviews (in fact, the ‘AI audit’ where somebody just plugs your account data into Claude or ChatGPT and lets rip is becoming increasingly common)

Automation and AI can help flag things to investigate (and AI is excellent in some circumstances such as assessing large volumes of search terms) but I’d want to know whether someone has actually checked the findings and considered the context.

None of this means every free audit is poor or without merit or insight. It means you should understand what you’re receiving and the commercial incentive behind it.

Why pay for a Google Ads audit?

The main reason I believe in paid audits is that the auditor can be compensated for doing the review itself.

They don’t have to win your ongoing management business to make the exercise worthwhile.

That creates more room for an objective assessment, including conclusions that wouldn’t make a particularly effective sales pitch.

A paid auditor can recommend staying with your current provider

In my experience, it’s very unusual for a free agency audit to conclude:

“Your current provider is doing a reasonably good job. There are a few things worth discussing, but I’d stick with them.”

Commercially, you can see why. If that’s the recommendation, there probably isn’t a new management contract coming out of it. This is hardly a compelling business model.

However, it can be (and often is) exactly the advice the client needs.

I frequently recommend staying with the existing agency, freelancer or in-house manager when the evidence supports that recommendation. Of the recent audits I’ve completed, over half have made this recommendation, or sometimes recommended continuing but trying to get changes to the management and fee structure.

There may still be improvements to make. But finding some opportunities doesn’t automatically mean the person managing your account needs replacing. Sometimes it is just about providing an opportunity to approach them with a fresh perspective to ‘reset’ the working relationship.

Because I’m being paid for the audit, I can give that advice without needing you to move your account to me. That is the one big difference between a free and paid Google Ads audit.

Paying for the review allows time for investigation

A paid audit also allows time to be allocated to the work without relying on a future sale to cover it.

That matters when an account needs more than a quick scan for obvious errors.

For example, an apparent performance problem might need investigation into what is being counted as a conversion, whether the enquiries are useful, or whether expectations are realistic for the available budget.

Those questions take time. They also tend to produce more useful recommendations than simply finding settings to criticise.

Of course, paying doesn’t guarantee a thorough or unbiased audit. You still need to check the scope and understand whether the provider is also trying to sell you something else.

The advantage is strongest when the audit is a worthwhile, standalone service for both you and the person delivering it.

Should you choose a free or paid Google Ads audit?

I’d base the decision on what you need from the review.

A free audit can make sense if:

• Your budget is tight and you need somebody to take a look.
• You want an initial view of potential account issues.
• You’re already considering a new provider and want to understand their approach.
• You’re comfortable assessing the findings as part of a sales conversation.

A paid audit is generally the better fit if:

• You want an independent assessment of performance and opportunities.
• You want a fair review of your agency, freelancer or in-house team.
• You need help distinguishing significant problems from minor housekeeping.
• You want recommendations you can act on with your existing provider.

For me, the key test is whether the auditor can comfortably tell you that your account is broadly sound and your current provider deserves to keep the work, and be honest in doing so.

If that conclusion is effectively off the table before the review starts, I’d question how “independent” the audit really is.

My view: pay for independence if that’s what you need

Although I’m very obviously biased, I believe a paid Google Ads audit is the better option when your main goal is an independent, objective understanding of how your account is performing.

That’s particularly relevant if you’re trying to assess your current provider. You need someone who can fairly identify both good work and genuine shortcomings.

If cash is limited and you just need somebody to take a look, a free audit can still be useful. Particularly if you have a specific ‘burning problem’ you want identified. Go into it understanding the sales process, and ask the provider to explain why each finding matters.

My own, comprehensive Google Ads audits start from NZD $750 + GST, with the scope and price depending on your requirements. You’re paying for my assessment, and my compensation for the audit isn’t dependent on selling you ongoing management.

If the evidence says you should stay with your current provider, that’s what I’ll tell you. You can learn more here about my Google Ads audit service.
