Choosing a digital marketing agency in the UK: 12 questions to ask first

Hiring a marketing agency is one of the higher-stakes decisions a UK small business owner makes. Get it right and a good partner quietly compounds the business for years; get it wrong and you lose not just the fee but the opportunity cost of the months you waited for results that never came. These are the 12 questions we'd ask if we were the ones writing the cheque.

Scope and structure

• 'Exactly what deliverables do I get each month?' If the answer is vague, the deliverables will be vague. A good agency can send you last month's report from another (anonymised) client on the call itself.
• 'Who will actually be doing the work?' Important. In most agencies, the person pitching the contract isn't the one doing the work once it starts. Ask to meet the people who will.
• 'How do you decide priorities each month?' Look for a clear process — audit, priorities, execution, review. If the answer is a gut-feel monologue, treat it as a yellow flag.

Pricing and contracts

• 'Is your fee a percentage of ad spend?' On Google Ads, this is a structural conflict of interest. A flat fee keeps the agency aligned with results, not spend.
• 'What's the minimum commitment?' SEO needs 3+ months to show meaningful movement; PPC can go month-to-month. Any agency wanting a 12-month tie-in up front without a performance clause is asking for too much trust.
• 'What happens when we want to leave?' The honest answer is 30 days. The dishonest answer involves clawbacks, exit fees, or losing access to assets you paid for.

Reporting and accountability

• 'Can I see a sample of your monthly reporting?' It should be in plain English, show the metrics that actually tie to revenue, and be less than five pages. Dashboards with fifty metrics are hiding.
• 'What does success look like after three months? Six? Twelve?' They should have a view, with caveats. 'We can't predict' is not a great answer; 'here's a realistic range based on your market' is.
• 'How often do we speak?' Monthly call as a minimum. Quarterly reviews are where strategy actually gets re-examined.

Work, references and red flags

• 'Can I see three clients in businesses roughly my size?' Not logos on a homepage — three case studies with numbers, contacts (with permission) and the actual work.
• 'What won't you do?' Good agencies say 'we don't do X, Y, Z' clearly. Anyone claiming to do everything at senior quality for every size of client is stretching.
• 'How do you handle it when a campaign isn't working?' Listen for 'we change it' or 'we stop and re-scope'. If you hear 'we give it longer' without a rationale, walk.

The three red flags

• Guaranteed page-one rankings. Nobody can guarantee these. Anyone who says they can is either lying or about to get your site penalised.
• Percentage-of-ad-spend PPC fees. Structural misalignment.
• Long contracts with no performance clauses. Agencies confident in their work don’t need you locked in.

“Agencies that are confident in their work don't need to lock you in. Ones that aren't, do. That's usually the signal you need.”

And one last question — ask them: 'If I told you my budget was a third of what you're pitching, what would you recommend I do instead?' A good agency will have a thoughtful answer. A sales machine will try to persuade you to stretch. The first one is the partner; the second one is the mistake.
