Hiring a freelance Google Ads consultant: when, how much, and how to choose

A freelance Google Ads consultant is an independent specialist who builds, runs and optimises your advertising on Google (Search, Shopping, Performance Max, YouTube). You work directly with the person whose hands are in your account, with no project manager in between. It's often the right choice when your ad budget is too big to be managed "between two meetings", but not big enough to justify an agency or a full-time hire.

In this article: the signs that it's time to get help, what a freelancer actually does, pricing models, and the questions to ask before you sign.

5 signs it's time to hire a freelance Google Ads consultant

1. You don't know what each euro or dollar spent brings back. Google Ads shows conversions, but they don't match your actual sales. Until conversion tracking is reliable, every decision (budgets, bids, keywords) is built on sand.

2. Cost per sale keeps rising and nobody knows why. Competition, higher CPCs, a Performance Max campaign eating your brand traffic, an incomplete product feed: there are many possible causes, and they need to be isolated one by one.

3. Your account hasn't changed since it was set up. Google keeps changing its formats and bidding strategies. An account built three years ago and never updated almost always leaves money on the table.

4. You run the ads in the evening, after everything else. If you, the founder, manage the campaigns, the real cost isn't just the ad budget: it's your time.

5. Your agency sends reports you don't understand. A good provider should be able to explain in two sentences what works, what doesn't, and what they'll do next.

The #1 mistake I find when I take over an account: the wrong conversion

When I take over a Google Ads account, the most frequent problem is neither the ads nor the keywords. It's the conversion: what the account counts as a success. It comes in two forms.

The conversion sits too high in the funnel. The account counts a page visit, or a click on a button leading to another page, as a "conversion". These are useful signals to record (Google lets you track them as secondary actions, without them driving your bids), but they are not conversions. A conversion should be an action that has real value for your business:

• in e-commerce: a purchase, or at least an add-to-cart or a started checkout;
• in B2B: a quote request or a completed contact form.

The problem is that Google's automated bidding learns from whatever you designate as a conversion. Ask it for button clicks, and it will go after people who click, not people who buy. Cost per "conversion" drops, the dashboard looks great, but those leads aren't qualified. Your final conversion rate falls, and you lose money anyway.

The conversion is poorly tracked. The right action is chosen, but the tag is badly set up: duplicate conversions, sales that never show up, missing order values. I always test the tracking (one real action end to end, then a check of what Google records) before touching anything else.

Either way, the result is the same: the campaigns optimise for the wrong thing. No bid or keyword tweak can make up for a badly defined goal. Google's help centre explains how conversion measurement works, including the difference between primary and secondary actions.

What a freelance Google Ads consultant (actually) does

The visible part is the campaigns. But most of the work happens before and around them:

On the e-commerce accounts I take over, I work hands-on with the three formats that drive most sales: Search, Shopping and Performance Max. My first move is almost always the same: check that the conversions reported by Google match the sales actually recorded in the store. Until those two numbers are reconciled, I don't touch the bids.

Freelancer, agency or in-house hire?

There's no one-size-fits-all answer, but there are typical situations:

• Freelancer: you want an experienced person working directly in your account, with a flexible commitment. A good fit for SMEs and growing online stores.
• Agency: you need several skills in parallel (video production, several languages, high volumes) and accept a salesperson or project manager between you and the people doing the work.
• In-house hire: advertising represents a budget and a workload that justify a full-time role, and you have someone to manage that person.

A freelancer can also work alongside an agency: an independent audit, steering the strategy, or taking over a single channel. It's often the fastest way to find out whether your current provider is doing a good job.

How much does a freelance Google Ads consultant cost?

Three pricing models coexist:

1. Day rate: you pay for time spent. Clear for an audit or a setup.
2. Monthly retainer: a defined scope (management, optimisation, reporting) for a fixed price. The most common model for ongoing management.
3. Percentage of ad spend: simple, but it creates a bias, since the provider earns more when you spend more. If you choose it, tie it to a profitability target.

Market prices vary enormously: freelance platforms list day rates below €200, while senior consultants charge from several hundred to over a thousand euros a month for account management. These figures aren't directly comparable, because they don't cover the same work: "setting up a campaign" has nothing to do with "running an account for profit".

I work on a quote basis, after a first conversation about your account. What drives the price: the number of campaigns and products, the state of your existing tracking, the number of countries and languages, and the level of support you expect (execution only, or steering your whole acquisition strategy).

The right calculation isn't the freelancer's fee, but what they earn or save you on your ad budget. A cheaper provider who lets unprofitable campaigns run costs more than it seems.

7 questions to ask before you sign

1. "What will you look at in the first week?" The right answer talks about conversion tracking and profitability, not "new ads".
2. "How do you measure profitability?" Be wary of a provider who only talks about the ROAS reported by Google, without reconciling it with your sales and your margin.
3. "Have you managed Performance Max and Shopping before?" For an online store, it's a must. Ask how they stop Performance Max from capturing your brand traffic.
4. "How often will we review, and on which metrics?"
5. "What happens if we stop?" You must keep your account, your history and your audiences.
6. "Do you also work on the website and other channels?" A perfect campaign that sends traffic to a product page that doesn't convert is still a bad campaign.
7. "Can you show me a sample report?"

Access: stay in control of your account

This is the most overlooked point, and the one that causes the most trouble when a collaboration ends. Google Ads offers several access levels: admin, standard, read-only, billing and email-only.

• Keep admin access inside your company. Only this level can manage users.
• Give your freelancer standard access: it's enough to manage campaigns. For a one-off audit, read-only is enough.
• The account must be in your name. A provider who creates the account on their side keeps your history if they leave.

Google itself recommends giving each user the minimum access they need.

How working with me goes

I work in three stages, as I do for every channel:

1. Read the real numbers: audit of the account and conversion tracking, reconciliation with your sales and margin, quantified goals.
2. Activate and test: priority fixes first, then structured tests, each with a clear hypothesis.
3. Measure, connect, scale: keep what pays off, cut the rest, and feed what we learn into the other channels (SEO, website, email).

And because I work on growth as a whole (ads, SEO, conversion, CRM), I also see what happens after the click. To learn more about my e-commerce approach, see the dedicated page, or my background in France and Japan.

Looking for someone to run your whole acquisition, not just Google Ads? Work with a freelance digital marketing consultant who makes all your channels work together.

I commit for a minimum of three months. It's not a sales clause, it's the time an account needs:

• the first month is spent taking over the account, analysing the whole customer journey (from ad to sale) and understanding your business;
• tests need time to produce reliable results;
• Google also needs time and conversions to learn to optimise for a new goal.

So you can't expect an account to deliver, at the end of month one, the results it will deliver at the end of month three, once the customer journey has been improved with your teams and the campaigns are realigned on the right conversion.
