How to Choose a Dental Marketing Agency in the UK

Part of the complete dental marketing guide for UK practices. After 12 years in this industry and over £100 million in tracked ad spend, I've seen the agency selection mistakes that cost practices years of wasted budget. This guide is the checklist I'd give a friend before they signed with anyone — including us.

Why the wrong agency is worse than no agency

A bad dental marketing agency doesn't just fail to grow your practice. They actively damage it: burning through your ad budget on poorly targeted campaigns, generating leads your team can't convert, and locking you into long contracts while producing monthly reports full of meaningless metrics. The opportunity cost of 12 months with the wrong agency is significant. So is the goodwill damage when patients have poor experiences triggered by an over-promised marketing campaign.

The 10 questions to ask any dental marketing agency

1. Do you work exclusively with dental practices?

Not a dealbreaker, but it matters. A generalist agency running campaigns for a hotel, a solicitor, and a dental practice is splitting their attention across three entirely different patient/customer journeys. An agency that specialises in dental understands treatment pricing, patient anxiety, GDC and ASA compliance, and which keywords actually convert. Ask how many dental practice clients they currently work with.

2. Who will actually manage my account day-to-day?

The most common agency disappointment story: you meet a senior specialist in the sales meeting who presents an impressive strategy, you sign — and then your account gets handed to a junior executive who has never run a dental campaign. Ask directly: who will manage my account? What is their experience? Can I speak to them before signing?

3. Can you show me a campaign you've run for a dental practice, including the results?

Any agency worth working with can show you real campaign data. Not a case study PDF with vague statements about 'increased enquiries'. Actual Google Ads data, actual SEO ranking improvements, actual cost-per-booked-consultation figures. If they can't or won't show this, assume they don't have results worth showing.

4. How do you track results — specifically, how do you connect an ad click to a booked patient?

This is the technical question most agencies stumble on. Good agencies track calls with call tracking numbers, form submissions with conversion events, and — ideally — import offline conversions back into Google Ads so the algorithm can optimise for actual booked patients, not just clicks. If the agency says they measure success by 'impressions' or 'click-through rate', walk away.

5. What is your approach to follow-up on web enquiries?

Generating enquiries is only half the job. The conversion rate from enquiry to booked consultation is heavily dependent on speed of response. Ask the agency what happens after a patient submits a form. Does your team call immediately? Is there automated SMS follow-up? What is the nurture sequence for leads who don't convert on first contact? An agency that generates leads and then considers their job done is leaving most of your return on the table.

6. What is your minimum ad spend recommendation, and why?

The answer tells you a lot. An agency that says '£500/month is plenty' either doesn't understand your market or is prioritising getting your business over getting you results. The minimum viable ad spend for meaningful Google Ads results in most UK dental markets is £1,000–£1,500/month. Below this, you won't accumulate enough data to optimise and won't generate enough clicks to fill appointment slots. See the full dental marketing cost guide.

7. What is your contract length, and what happens if you don't deliver?

Agencies that are confident in their results work month-to-month or on short notice periods. Agencies that lock you into 12-month contracts are protecting themselves, not you. Ask specifically: if you don't deliver new patient enquiries in the first month, what recourse do I have? The answer is telling.

8. Do you work with any of our competitor practices in the same area?

Not necessarily a dealbreaker, but you deserve to know. An agency managing your Google Ads campaign and that of the practice two streets away is in an inherent conflict of interest. At minimum, you should know this is the case before you sign.

9. How do you stay current with Google Ads and SEO changes?

The paid search and SEO landscape changes continuously. An agency that hasn't updated its approach in two years may still be running strategies that no longer work — or worse, strategies that now actively harm your rankings. Ask what changed in their approach in the last 6 months and why.

10. Can I speak to two or three current clients?

The most important question. An agency confident in their work will give you references without hesitation. If they say client confidentiality prevents this, they're hiding something. Google reviews are useful but easy to game — a direct conversation with a current client is the best due diligence you can do.

Red flags: walk away if you see these

• Guaranteed #1 Google rankings. No one can guarantee organic rankings — it violates Google's own guidelines and is a sign of either ignorance or dishonesty.
• Proprietary 'black box' reporting. If you can't see your own Google Ads account data, your own analytics, your own campaign performance — that's a control issue. You should own and have full access to everything.
• No conversation about GDC and ASA compliance. Healthcare advertising in the UK has specific rules. An agency that has never mentioned compliance is either inexperienced in dental or sloppy.
• Testimonials only — no data. Anyone can collect a positive testimonial. What matters is numbers: enquiries generated, cost per enquiry, conversion rate to booked patients.
• They promise to make your phone ring off the hook immediately. Unrealistic expectations are a setup for disappointment and disputes. Google Ads can generate enquiries quickly; a full marketing system takes 60–90 days to optimise.

Green flags: signs of an agency that delivers

• They ask detailed questions about your practice before pitching anything — number of chairs, which treatments generate most revenue, average patient lifetime value, current enquiry volume
• They're selective — they tell you if your practice isn't the right fit, rather than taking on every client who'll pay them
• They show you real data from real clients — specific numbers, not vague 'we grew their revenue' statements
• They talk about follow-up systems and conversion, not just lead generation
• Month-to-month contract with a clear performance benchmark
