Poorly targeted dental Google Ads waste budget on clicks from people who will never book with you. This guide shows practice owners how precise geo-targeting fixes that problem and fills your appointment book with genuinely local patients.
If you have ever looked at your Google Ads account and wondered why you are paying for clicks from people who are clearly nowhere near your practice, you are not alone. Many dental practices across South Yorkshire and North Derbyshire run pay-per-click campaigns that haemorrhage budget on searches from entirely the wrong locations. The clicks look legitimate on paper, the search terms are relevant, but the callers either never book or ask whether you are "anywhere near" a town that is forty minutes away. The root cause, in almost every case, is weak or misconfigured geo-targeting. Getting this right is one of the highest-return technical improvements you can make to a dental PPC campaign, and it costs nothing extra once it is set up correctly.
Google Ads offers location targeting settings that look straightforward at a glance. You type in a city, a region, or a postcode district, and Google promises to show your ads there. The problem is in the detail, specifically in a setting that most practices and generalist agencies overlook: the difference between targeting people in a location and targeting people who have "shown interest in" that location.
By default, Google Ads includes both groups in its targeting. That means someone sitting in Manchester who has been searching for information about Rotherham dentists could see your Rotherham practice ad. They are almost certainly not going to book an appointment with you. You have paid for that click, and it converts at a fraction of the rate a genuinely local search would.
Beyond this default setting, there are several other ways location targeting falls apart for dental practices:
Before you can geo-target correctly, you need an honest picture of where your patients actually come from today. Pull your patient records and map the postcodes of your existing registered patients. For most general dental practices, the majority of patients live within a two-to-four-mile radius of the surgery. For specialist services such as implants, orthodontics, or facial aesthetics, that radius typically extends further because patients are willing to travel for a provider they trust.
This exercise often produces a surprise: the geographic spread of existing patients rarely matches the radius a practice initially targets in Google Ads. Many practices discover they are paying for clicks from postcodes that have never produced a single booked appointment, while underspending in streets that are packed with their ideal demographic.
Once you have your actual patient postcode data, cross-reference it with Google Ads location reports. In your campaign, navigate to the "Locations" section and look at performance by city, postcode district, and region. You will almost certainly see significant variance in cost per conversion across different areas. This data should drive every subsequent targeting decision.
With your catchment data in hand, here is how to build a location strategy that actually works for a dental practice.
This is the single most impactful change many practices can make. In your campaign settings, under "Location options," switch from the default "Presence or interest" to "Presence: People in or regularly in your targeted locations." This alone can dramatically reduce wasted spend on searches from people outside your catchment area.
Rather than targeting "Sheffield" as a city and hoping for the best, build your geographic targeting from postcode districts outwards. Add the specific districts where your patient data tells you conversions come from. Then add negative location exclusions for districts that consistently show clicks but no conversions.
Google Ads allows you to increase or decrease your bids by location. If your data shows that patients from one particular postcode sector convert at twice the rate of another, you should be bidding more aggressively for those locations. Set positive bid adjustments, typically in the range of ten to thirty per cent, for your highest-converting areas, and negative adjustments for peripheral areas you still want to appear in but with reduced spend.
Radius targeting centred on your practice postcode is useful, but the radius needs to reflect your specific geography. In a dense urban area like central Sheffield, a one-to-two-mile radius may be entirely sufficient for general dentistry. In a more rural part of North Derbyshire, a four-to-six-mile radius may be necessary to reach enough potential patients. There is no universal answer, which is why using your own patient data rather than a default setting matters so much.
Advanced practice owners and their agencies will take this a step further by running separate campaigns for different services, each with its own geographic parameters. Your Invisalign campaign might justifiably target a larger radius than your general check-up campaign, because patients seeking cosmetic treatment are more willing to travel. Mixing these in a single campaign with unified location settings forces a compromise that serves neither service well.
A generalist pay-per-click agency managing dozens of industries at once is unlikely to know that a practice in Chesterfield has a fundamentally different catchment dynamic to one in Doncaster, or that patients in certain parts of Sheffield cross postcode district boundaries to reach practices they perceive as higher-quality. This local knowledge shapes targeting decisions in ways that no generic template approach can replicate.
When Dental Marketing Pros manages dental PPC campaigns for practices across the region, the geo-targeting setup process begins with a proper discovery phase. We map existing patient postcodes, review historical campaign location data where available, and cross-reference both against local demographic information. Only then do we build a location structure.
Ongoing management is equally important. Location performance data is reviewed monthly, and bid adjustments are refined as real conversion data accumulates. A location that looked marginal at setup may prove to be a strong performer once there is sufficient data; conversely, a location that seemed obvious may consistently underperform. Static geo-targeting set once and left alone will always be outperformed by a campaign that evolves with the data.
We also work with practices across a range of towns and cities in the region, and you can see the areas we cover on our locations page. Understanding the local competitive landscape in each of these areas informs how aggressively we target certain postcodes and how we frame ad messaging to resonate with patients in specific communities.
Properly configured geo-targeting does not guarantee any specific result, and it would be misleading to suggest otherwise. What it does do is ensure that your budget is concentrated on the searches most likely to result in a genuine patient booking. For a practice spending a meaningful sum each month on paid search, removing wasted spend on out-of-area clicks and reallocating it towards your strongest-converting postcodes can materially improve the efficiency of the entire campaign.
It also improves the relevance of your ads. When you know precisely which postcode you are targeting, you can write ad copy and choose landing page content that speaks directly to patients in that area. Mentioning a local landmark, a nearby transport link, or simply naming the town or village explicitly in your headline makes your ad feel immediately more relevant to the person seeing it. Relevance improves click-through rates, and higher click-through rates improve your Quality Score, which in turn reduces the cost per click you pay. Good geo-targeting is not just a budget protection measure; it feeds into the overall health of your campaign.
If you are currently running Google Ads without a clear geo-targeting strategy based on your own patient data, the most useful thing you can do this week is pull your location reports and map what you find. If what you see raises questions, or if you would like a second opinion on how your current campaign is targeting patients in your area, we are happy to take a look.
Dental Marketing Pros works exclusively with dental practices across South Yorkshire and North Derbyshire, so we understand the local market rather than applying a generic national template to your campaign. If a conversation about your current paid search activity would be useful, you are welcome to get in touch with our team at a time that suits you. There is no obligation, and we will give you an honest assessment of where your current targeting may be costing you more than it should.
