Most dental Google Ads campaigns underperform not because of poor targeting, but because the ads themselves are doing the bare minimum. This guide explains exactly which ad extensions to use and why they matter for your practice.
If your Google Ads campaigns are generating clicks but not enough new patient enquiries, the problem often is not your keywords or your budget. It is your ads. Specifically, it is what your ads fail to show. Google gives advertisers a range of free tools to make their ads larger, more informative and more relevant, yet the majority of dental practices running paid search campaigns either ignore them entirely or activate only one or two by accident. These tools are called ad extensions, now formally referred to by Google as "assets," and using them well is one of the highest-impact, lowest-cost improvements any practice can make to its PPC account.
This article explains the extensions that matter most for dental practices in the UK, why each one works, and how to set them up so they actively qualify patients rather than simply attracting more of the wrong clicks.
Google Ads operates an auction system where your ad position is determined not just by your bid, but by your Quality Score, which includes expected click-through rate and ad relevance. Extensions improve both. A well-extended ad occupies more screen space, communicates more useful information before the click, and gives Google's algorithm more signals to serve your ad in relevant contexts. The practical result is that extended ads typically achieve higher click-through rates than bare-bones text ads at the same bid level.
For dental practices specifically, extensions solve a particular problem. Dentistry is a high-consideration, high-anxiety purchase for many patients. People searching for a dentist in Rotherham or Sheffield are often comparing several options simultaneously. An ad that shows your location, your opening hours, your specific services and a link to your patient registration page gives a prospective patient far more reason to choose you over a competitor whose ad shows only a headline and a URL.
Our dental PPC service builds extension structures into every campaign from the outset, because retrofitting them after launch means losing early data and often means the account has already wasted spend it did not need to.
Sitelinks are additional links that appear beneath your main ad, directing users to specific pages on your website. They are the single most important extension category for dental practices and the one most commonly misused.
Effective dental sitelinks do not simply replicate your navigation menu. They are written with search intent in mind. A user searching for "Invisalign Sheffield" is in a very different mindset to someone searching for "emergency dentist Doncaster." Your sitelinks should reflect that difference.
Useful sitelink targets for most dental practices include:
Write sitelink headlines that are specific and action-oriented. "Book a Consultation" outperforms "Contact Us." "Dental Implant Prices" outperforms "Implants." Add description lines to each sitelink where possible; these appear when Google has enough screen space and add another layer of qualifying information.
Call extensions add your phone number directly to the ad, allowing mobile users to call your practice without visiting your website at all. For many patients searching on a smartphone, this is the fastest path to booking, and for your practice it is often the highest-intent enquiry you can receive.
The critical configuration detail that most practices overlook is scheduling. You can restrict call extensions so they only show during your practice opening hours. This matters significantly. A patient who taps your number at 10pm on a Sunday and reaches an answerphone is unlikely to call back. Worse, you have paid for that click. By limiting call extension display to the hours your reception team is available, you improve the patient experience and reduce wasted ad spend in a single setting.
If your practice uses a CRM or call-tracking system, connect it to your Google Ads account so you can attribute booked appointments to specific campaigns. Without this, you are flying blind on which keywords are actually generating phone calls.
Location extensions pull your practice address from your Google Business Profile and display it beneath your ad. For local service businesses like dental practices, this is fundamental. Patients want to know you are nearby before they click, and seeing your town or postcode in the ad itself is a powerful relevance signal.
To use location extensions, your Google Ads account must be linked to a verified Google Business Profile. If your practice has not yet claimed and verified its profile, that is a separate priority, but do not wait on it before building the rest of your campaign structure.
Location extensions also feed into Google's local search formats and map placements, which means they have broader benefits beyond the standard search results page.
Callouts are short phrases, typically between 12 and 25 characters, that appear in a row beneath your ad text. They cannot be clicked. Their purpose is to communicate practice-level proof points quickly, in the way a patient might scan a billboard.
Strong callouts for dental practices tend to highlight things that differentiate you from NHS provision or from the average high-street competitor. Examples include:
Keep callouts factual and accurate. The ASA and GDC hold dental advertising to strict standards, and claims must be substantiated. Do not write "Best Dentist in Sheffield" or imply clinical superiority you cannot evidence. Stick to objective practice attributes.
Structured snippets let you list specific items under a predefined header. For dental practices, the most useful headers are "Services" and "Types." These extensions help patients quickly establish whether your practice offers the treatment they are searching for, which reduces irrelevant clicks and improves the quality of your enquiries.
A services structured snippet might read: Dental Implants, Invisalign, Composite Bonding, Teeth Whitening, Hygiene Appointments, Emergency Dentistry. This gives the ad a catalogue quality that plain ad text cannot achieve.
Image extensions allow you to attach a visual to your search ad. For dental practices with a modern, photogenic clinic or a strong before-and-after portfolio, these extensions can meaningfully increase engagement. Use genuine, high-quality photography of your actual practice. Stock images perform poorly here and can create a mismatch when a patient arrives expecting something different.
Note that image extensions must comply with Google's editorial policies and must not be misleading. Treatment result images must represent realistic outcomes and must not imply results that are not typical.
Lead form extensions open a Google-hosted enquiry form directly within the search results page, without requiring the user to visit your website. For practices that struggle with website conversion rates, this can be a useful interim tool. Patients can submit their name, email and phone number in seconds.
The limitation is that these leads tend to be lower intent than website visitors who have read your treatment pages and viewed your team. Use them selectively, perhaps for high-volume campaigns like general enquiries or new patient registrations, rather than for complex, high-value treatments where patient education before the call matters.
The most common mistake is treating extensions as a one-time setup task. Extensions require the same ongoing review as your keywords and ad copy. Google rotates extensions automatically based on predicted performance, which means a poorly written callout or an outdated sitelink can suppress your better assets without you realising.
The second mistake is using the same extensions for every campaign regardless of intent. A campaign targeting "emergency dentist" should prioritise call extensions and location extensions above all else. A campaign targeting "dental implants Sheffield" should lean heavily on sitelinks to treatment information, pricing and consultations. Generic, campaign-agnostic extensions reduce relevance and therefore reduce both click-through rates and Quality Scores.
The third mistake is failing to monitor extension performance data in the account. Google Ads provides impression, click and conversion data broken down by extension type and by individual extension. Practices that review this data regularly can cut underperforming sitelinks, test new callout combinations and adjust their extension scheduling to match actual booking patterns.
A specialist dental PPC agency does not simply tick the "extensions enabled" box and move on. Extension strategy is built campaign by campaign, informed by the treatments you want to grow, the patient profile you are targeting and the competitive landscape in your specific geography.
In South Yorkshire and North Derbyshire, where many practices are competing for a similar patient base across Sheffield, Rotherham, Barnsley, Doncaster and Chesterfield, the difference between an extended ad and an unextended one can be the difference between appearing dominant on the results page and appearing like an afterthought. Patients form impressions quickly, and the ad they see is often their first contact with your brand.
Beyond the initial build, an experienced agency will run scheduled extension audits, conduct A/B tests on callout and sitelink variants, align extension changes with seasonal trends (January new patient registration drives, for example, or pre-summer whitening campaigns), and ensure all copy remains compliant with GDC and ASA advertising standards throughout.
Our PPC campaigns for dental practices are built with this level of structure from day one, because fixing a poorly structured account later always costs more than building it correctly at the start.
If you want to audit your current extensions quickly, log into your Google Ads account, navigate to the "Assets" section (previously called Extensions), and check which asset types are active. For each one, review the performance data and ask whether the copy still reflects your current offer, your current opening hours and your current priority treatments.
If you have no extensions active at all, start with sitelinks, call extensions with scheduling, and callouts. These three alone will give your ads significantly more presence on the results page and will begin qualifying patients before they click, which is where the real efficiency gains come from.
