Why this question is harder to answer than it looks
Most comparisons of freelancers versus agencies end up being marketing material for one side or the other. Agencies write about the dangers of relying on a single person. Freelancers write about the horrors of being handed off to a junior account manager you've never met.
The reality is more nuanced. Both options have genuine strengths and genuine weaknesses. The right answer depends on the size of your account, how much access you want to the person managing it, and what you're actually trying to achieve.
What you get with a freelancer
When you hire a Google Ads freelancer, you are hiring a specific person. The person you speak to in the sales conversation is the person managing your account. That is the single biggest practical difference between freelancers and agencies.
This matters because Google Ads performance is largely a product of the decisions made inside the account. The more experienced and focused the person making those decisions, the better the results tend to be. With a freelancer, you know exactly who that person is.
Freelancers also tend to cost less. Without office overheads, account management layers, and business development costs to cover, a freelancer can typically offer comparable expertise at a lower monthly fee.
The trade-offs are real though. A freelancer has a finite amount of time, and if your account is complex or you're running across multiple channels, a single specialist may eventually hit a capacity ceiling. Cover during holidays or illness can also be a concern, though most experienced freelancers have arrangements in place for this.
What you get with an agency
Agencies offer the reassurance of a team behind your account. There are usually multiple people who understand your campaigns, which reduces the risk of things falling apart if one person leaves. For very large accounts, or businesses running paid search alongside paid social, programmatic, and other channels, an agency with specialists in each area can be genuinely useful.
The problem is that the quality of an agency varies enormously depending on who is actually managing your account day to day. Senior strategists tend to win the business. Junior account managers tend to run it. The person who impressed you in the pitch meeting may have very little involvement in your campaigns once you sign.
Agencies also cost more, and their pricing structures are not always straightforward. Management fees, percentage of spend models, and setup costs can make it difficult to understand what you are actually paying for.
The question worth asking any agency: who specifically will be managing my account, and what other accounts does that person currently manage? The answer tells you more than any credentials or case studies.
How to decide
The honest answer is that budget and scale usually make the decision for you.
If your monthly ad spend is under £50,000 and you're running Google Ads as your primary paid channel, a good freelancer will almost always outperform an agency at the same price point. You get more senior attention, more direct communication, and lower fees that leave more budget available for the ads themselves.
If you're running significant spend across multiple channels, have complex international campaigns, or genuinely need a team of specialists across different disciplines, an agency may be the better fit.
The threshold is not fixed. Some freelancers comfortably manage accounts spending several hundred thousand pounds a month. Some agencies provide excellent service to smaller businesses. But as a general guide, the £50,000 monthly spend figure is roughly where the argument for an agency starts to become more compelling.
Questions to ask before you commit to either
Whether you're evaluating a freelancer or an agency, the same questions apply.
- Who will actually manage my account? Get a name. Then look at their experience.
- How many other accounts does that person manage? A specialist stretched across 40 accounts will not give yours meaningful attention.
- What does the reporting look like? Ask to see an example. Vanity metrics and busy dashboards are not the same as useful analysis.
- What happens if performance drops? You want a clear answer about how problems are identified and what the response process looks like.
- What is the contract length and notice period? Be cautious of long lock-in periods before you've seen results.
A note on pricing models
Both freelancers and agencies typically charge either a flat monthly management fee or a percentage of ad spend.
Percentage of spend models have an obvious problem: the more you spend, the more the person managing your account earns. That is not necessarily aligned with your interests. A flat fee means the incentive is to improve performance rather than to grow spend.
Fixed fee management is increasingly common among experienced freelancers. It's worth asking whether the person or agency you're considering uses this model, and if not, why not.
Worth knowing: JWC Performance charges a fixed monthly fee for account management. No percentage of spend, no hidden charges. See how it works.
The bottom line
Neither freelancers nor agencies are inherently better. What matters is the quality of the person or people managing your account, the structure of the engagement, and whether the approach is actually suited to the size and complexity of your campaigns.
For most UK SMBs running Google Ads at a sensible scale, an experienced freelancer offers better value, more direct access to expertise, and a cleaner working relationship. But do your due diligence either way. Ask the hard questions before you sign anything.
