Google Ads for Dentists: Making Every Pound Work Harder

Google Ads is the most expensive paid channel a London dental practice can run, and the most effective one when it is set up correctly. The cost per click for treatment-led searches has crept up year after year, and unless your campaigns are built around treatment value rather than click cost, you will be paying £15 to £30 per click and wondering where your patients are.

This guide covers how to structure a Google Ads programme for a private dental practice that produces booked consultations rather than wasted budget.

Stop bidding on the obvious words

The single biggest mistake practices make is bidding on broad treatment keywords. "Invisalign", "dental implants", "veneers", "Botox" on their own are competitive enough that you will be outbid by national chains, dental tourism providers, and direct-to-consumer aligner brands every time. Even when you do win the click, the search intent is mixed. Some clicks are research, some are price shopping, some are looking for a specific provider, and very few are ready to book.

The better play is long-tail intent that combines treatment with location, intent qualifier, or commercial signal. "Invisalign Mayfair", "dental implants near Marylebone", "cosmetic dentist Knightsbridge", "private dentist Chelsea same day", "veneers Harley Street price". These keywords have lower volume and lower CPC, and they convert far better.

The general rule is: the longer the keyword, the higher the intent and the lower the cost per acquisition.

Match types matter more than budget

Google Ads has three match types: broad, phrase, and exact. Broad will spray your budget across loosely related terms. Phrase keeps the order. Exact only shows for the precise term you specified. Most dental practices run on broad match because Google's interface defaults push you that way.

Switch to phrase or exact match for your top-performing keywords. Use broad match modifiers only for testing, with strict negative keyword lists. Build a negative keyword list from day one that excludes terms like "free", "NHS", "course", "training", "salary", "cheap", and "child". A clean negative list will save you a third of your wasted spend.

Review search terms weekly. The reports will show you exactly what people typed before they clicked your ad. Patterns will emerge. Add what works as exact match keywords, and add what does not as negatives.

Landing pages are 80 percent of the work

A campaign with the wrong landing page will fail no matter how clean the targeting is. Most dental practices send Google Ads traffic to their homepage. The homepage is too generic. A homepage tries to please every patient: NHS, private, kids, adults, all treatments. A landing page only needs to please one type of patient looking for one type of treatment.

Build a dedicated landing page for each high-value treatment campaign. The page needs: a headline that matches the search intent ("Invisalign in Mayfair from £X per month"), a fast-loading hero with one clear call to action above the fold, before and after photos from your practice, a short bullet list of what the consultation includes, pricing or pricing range with finance, two or three reviews from real patients, and a booking widget that books the consultation directly into your diary.

The booking widget is critical. Form-based enquiries that go to a shared inbox and get handled "tomorrow" lose 30 to 50 percent of leads. Direct booking through a tool like Dentally, SOEnow, or even a Calendly link converts at twice the rate.

Track what matters

A surprising number of dental practices run Google Ads without conversion tracking. They look at clicks and impressions, and have no idea which clicks turned into consultations.

Set up conversion tracking for: form submissions, booking widget completions, phone call clicks on mobile, and ideally calls of more than 60 seconds tracked through a call tracking number. If you do not track calls, you will be missing roughly half of your conversions because older patients still prefer to phone.

Send conversion data back to Google Ads. The auction algorithm uses this to optimise bidding, and a campaign with proper conversion data feeding back will outperform an identical campaign without it by a significant margin within three or four weeks.

Budget for treatment value, not click cost

A click for "Invisalign London" might cost you £20. If your average Invisalign case is worth £4,000 in revenue, you can afford to spend £200 to £400 on advertising per booked consultation, depending on your conversion rate at the consultation stage. That means you can afford 10 to 20 clicks per booked consultation.

Practices that under-budget Google Ads will spend £500 in a month, get 25 clicks, get one booked consultation, and decide that "Google Ads doesn't work". The maths is wrong, not the channel. To get reliable results from Google Ads for a high-value dental treatment, you need a budget of at least £1,500 to £3,000 per month per treatment campaign, sustained over three to six months so the algorithm has enough conversion data to learn from.

If your budget is smaller than this, focus on local SEO and Google Business Profile first. Google Ads will work for you, but only at a budget that gives the campaign a fair chance.

Day-parting and geo-targeting

A small dental practice does not need to advertise 24 hours a day across all of London. Day-parting (turning ads on and off based on time of day) and tight geo-targeting will sharpen your spend.

For most practices the highest converting hours are 9am to 6pm Monday to Friday plus Saturday morning. Evenings and Sundays are research time, not booking time. Reduce bids by 30 to 50 percent overnight. Your CPA will fall.

Geo-target to a 3 to 5 mile radius around the practice for general dentistry, and a wider radius (10 to 15 miles) for specialist treatments like implants where patients will travel further. Use bid adjustments to push harder in the postcodes that historically convert best.

A realistic timeline

A new Google Ads programme for a London dental practice usually shows clear performance signals within 4 to 6 weeks, but does not stabilise until month 3. Do not panic in week 2. Watch the data, kill the obvious losers, double down on the winners, and let the algorithm settle.
