Google Ads freelancer vs. agency: how to choose who runs your account

If your account needs judgement (structure, measurement, budget decisions) and someone who owns the results, a senior specialist managing it personally will usually outperform an agency at the same budget. If you need many disciplines at once, or more production capacity than one person can deliver, an agency or an in-house team makes more sense. The label matters less than one question: who touches your account every day, and how good are they?

Key takeaways

Ask who will actually operate the account, by name, and how many other accounts that person runs.
Your Google Ads account must belong to your company. Whoever manages it gets access through their manager account (MCC).
An agency fits when you need creative production, video and several platforms with dedicated teams.
A senior freelancer fits when the bottleneck is strategy and measurement.
An in-house team fits when spend justifies a full salary and there is a senior person to lead it.

The three options, without the sales pitch

Agency

A good agency gives you capacity, process and several disciplines under one roof. If you need a video campaign, a landing page redesign and reporting across three markets next month, they have people to assign.

The trouble comes from the most common business model. A partner or director sells the account, and then someone with less experience runs it, often alongside many other accounts, and sometimes leaves a few months later. It does not happen everywhere, and there are excellent agencies. But it is the pattern I see most often when I take over accounts that come from an agency: templated structures, undocumented changes, and nobody who can explain why a campaign is set up the way it is.

Senior freelancer

The person who sells you the work is the person who does it. You get direct access, decisions happen fast, and you are not paying for an office. For accounts where structure, tracking and budget allocation make the difference, that model works very well.

The limits are real. One person has finite capacity and, if they are a generalist, may not cover creative production. The question I would ask is whether that person has a system that does not rely on memory: checklists, automated monitoring and a log of every change. Without that, the quality of the work depends on how their week is going.

In-house team

Your own team knows the business better than anyone and is fully dedicated. It costs more than it looks: salaries, tools, training, and the risk of your senior hire leaving. A person who only sees one account also loses perspective. They cannot tell whether a CPC or a conversion rate is normal for the market.

In mid-sized companies, the setup that tends to work best is a small internal team with outside support. What helps most there is a senior specialist who reviews the account, sets priorities and trains the team, while the team executes.

Five criteria to decide

Who operates the account. The name of the person making changes, not the one signing the proposal.
Which conversion they will optimize for. If they talk about ROAS without asking about your margin, or about cost per lead without asking how many leads become customers, the account will grow on the wrong metric.
Ownership and access. Google Ads, Google Tag Manager, GA4 and Merchant Center should all be yours.
How you find out what is happening. Reporting frequency, which metrics are included, and how fast they reply.
How you exit. Notice period, minimum term, and what happens to your data if you part ways.

Questions to ask on the first call

Who will make changes in my account, and how many accounts does that person manage today?
Which conversion should my account optimize for, and why?
What would you do in the first 30 days?
How will I know what you changed and why?
What happens to the account, its history and the data if we stop working together?
What is the minimum monthly spend at which working with you makes sense?

If the answer to the last one is “any budget works”, be careful. Below a certain level of spend, automated bidding does not get enough data to learn, and the management fee ends up outweighing any improvement.

Red flags

They promise a ROAS, a CPA or a number of leads before seeing the account.
They want to create a new account under their MCC and do not give you admin access with a company login.
Reports show impressions, clicks and CTR, but never sales, margin or qualified leads.
They ask for a long lock-in before proving anything.
The fee rises automatically with spend and nobody explains what extra work justifies it.
Nobody asks about your margin, your average order value, or what happens to a lead after the form.

Who owns the account

You do. Always. The right setup is simple: the Google Ads account is created with a company email, billing is in your company’s name, and whoever manages it links it to their manager account (MCC) with the appropriate access level. If the relationship ends, the MCC is unlinked and all the history, campaigns and audiences stay in your account.

The same goes for your Google Tag Manager container, your GA4 property and Merchant Center. If any of those assets is currently owned by a vendor, fix that before you change who manages them.

How to think about cost

Comparing monthly fees alone leads to bad decisions. The real cost of management is the fee plus the spend that gets wasted.

Example: at USD 10,000 a month in ad spend, if 15% goes to irrelevant searches or to products with no margin, that is USD 1,500 a month. A USD 500 difference in fees between two options is small next to that. So the useful question is who will find and cut that waste faster, and who will measure properly enough to know where it is. If you sell online, my post on ROAS vs. POAS shows how to spot campaigns that generate revenue but no profit.

When an agency is the better choice

There are cases where I would recommend an agency myself:

You need ongoing creative production (video, display, catalog assets) on top of media management.
You run significant campaigns on several platforms and want a single vendor coordinating everything.
Your company requires a vendor with formal structure: procurement processes, master agreements or broad service levels.

If you go with an agency, ask for the senior specialist you met during the sales process to be named in the contract as the person responsible for your account.

How I work

I manage every account personally and keep my client list small on purpose. So that nothing depends on my memory, I use AI agents that check tracking, disapproved ads, quality and budget pacing every morning. I explain the setup in this post about AI agents. The full scope is on full-service Google Ads management.

Before you sign with anyone, ask for the name of the person who will touch your account and ask them which conversion they would optimize for. Those two answers will tell you more than any pitch deck.
