How we restructured a dental practice's Google Ads strategy to reduce cost per lead by 40% while quadrupling their conversion rate.

The Challenge

West Coast Dental is a multi-practitioner dental clinic in Perth's northern suburbs, offering general dentistry, cosmetic procedures, orthodontics, and emergency dental services. The practice had been running Google Ads for over two years through a generalist marketing agency, spending approximately $4,500 per month on search campaigns.

Despite the significant ad spend, results were deteriorating. Their conversion rate had dropped to 1.2% — meaning for every 100 people who clicked their ads, only 1 or 2 actually booked an appointment. Their cost per lead had ballooned to $185, making patient acquisition through Google Ads barely profitable given the average value of a new dental patient.

When the practice principal, Dr. Sarah Chen, contacted SimptechAI, she was on the verge of cancelling Google Ads entirely. 'We were spending $54,000 a year on ads that weren't working. My accountant was telling me to cut it. But I knew other dental practices were getting results from Google — I just couldn't figure out what we were doing wrong.'

The Audit: Diagnosing the Problems

Our initial audit of West Coast Dental's Google Ads account revealed systemic issues that are remarkably common across Australian healthcare practices running self-managed or agency-managed campaigns.

• Campaign structure: All services (general, cosmetic, emergency, orthodontics) were grouped into a single campaign with broad match keywords, meaning emergency dental searches triggered ads for cosmetic dentistry — wasting clicks on mismatched intent
• Keyword waste: 38% of ad spend was going to irrelevant search terms. We found clicks from searches like 'dental nurse jobs Perth,' 'free dental clinic Perth,' and 'dental school requirements' — none of which would ever convert to a paying patient
• Landing page mismatch: Every ad pointed to the homepage regardless of the search term. A patient searching for 'emergency dentist Perth' landed on a generic homepage with no emergency-specific content, no after-hours information, and no way to call directly
• No negative keywords: The account had zero negative keywords after 2 years of operation. This single oversight was responsible for the majority of wasted spend
• Geographic targeting: Ads were targeting all of Perth metro (1.8M+ population) instead of the northern suburbs within reasonable driving distance of the practice
• Ad copy: All 4 ads in the account were identical, written in 2023 and never tested or updated. No ad extensions were active despite being available at no cost
• Conversion tracking: Only form submissions were tracked. Phone calls — which represent 70-80% of dental appointment bookings — were not being measured. The actual conversion rate was likely higher than 1.2%, but they couldn't prove it

Our Strategy: Rebuild From the Ground Up

Rather than incrementally improving the existing campaigns, we recommended a complete rebuild. The account structure, keyword strategy, landing pages, and measurement framework all needed replacing. We proposed a focused 2-month engagement with three phases.

Phase 1: Account Restructure and Measurement (Week 1–2)

The first priority was fixing the foundation — measurement and campaign architecture.

• Installed call tracking on all ad-click phone calls, allowing us to attribute phone bookings directly to specific keywords and ads for the first time
• Created 4 separate campaigns aligned to the practice's core service categories: General Dentistry, Cosmetic Dentistry, Emergency Dental, and Orthodontics
• Built comprehensive negative keyword lists from 2 years of search term data — immediately blocking 200+ irrelevant terms like 'jobs,' 'courses,' 'free,' 'DIY,' and competitor brand names
• Tightened geographic targeting to a 15km radius around the practice, with bid adjustments increasing bids for searches within 5km (where conversion rates are highest for dental practices)
• Activated all relevant ad extensions: call extensions, location extensions, sitelinks to specific service pages, structured snippets listing services, and callout extensions highlighting differentiators ('Same-Day Appointments,' 'Payment Plans Available,' 'Open Saturdays')

Phase 2: Landing Pages and Ad Copy (Week 2–4)

With the campaign structure fixed, we built dedicated landing pages that matched ad intent — the single most impactful change in the entire project.

• Created 4 service-specific landing pages on the practice's website, each designed for a specific patient intent: 'Emergency Dentist Perth — Same-Day Appointments,' 'Cosmetic Dentistry Perth — Smile Makeovers,' 'Family Dentist Perth Northern Suburbs,' and 'Invisalign Perth — Clear Aligners'
• Each landing page featured: a prominent click-to-call button above the fold, same-day appointment availability messaging, patient testimonials specific to that service, transparent pricing where possible, and a simple 3-field booking form
• Wrote 3 responsive search ad variations per campaign (12 total), each testing different headlines, value propositions, and calls to action
• Implemented A/B testing between landing page variants to identify the highest-converting layouts and messaging

Phase 3: Optimisation and Scaling (Week 4–8)

With accurate tracking in place and dedicated landing pages live, we entered the optimisation phase — systematically improving performance using real conversion data.

• Identified that emergency dental searches converted at 8.2% (vs 2.1% for general dentistry) and shifted 35% of budget toward emergency campaigns during after-hours and weekend periods when competition dropped
• Discovered that 'near me' searches converted at 3x the rate of generic 'Perth' searches — added location-intent bid modifiers
• Paused 23 keywords generating clicks but zero conversions over 60 days — redirecting that spend to proven converters
• Implemented day-of-week and hour-of-day bid adjustments based on conversion data: increasing bids during Monday mornings (when emergency dental searches peak after weekend injuries) and reducing spend during low-conversion overnight hours
• Tested urgency-based ad copy ('Same-Day Emergency Appointments Available') vs benefit-based copy ('Gentle, Anxiety-Free Dental Care') — urgency messaging outperformed by 40% for emergency campaigns while benefit messaging won for cosmetic procedures

The Results

The transformation happened faster than even we anticipated. By the end of Month 2, every key metric had improved dramatically.

• Conversion rate: From 1.2% to 4.8% — a 4x improvement driven by landing page matching and negative keyword implementation
• Cost per lead: From $185 to $110 — a 40% reduction while maintaining the same ad spend budget
• Monthly leads: From 24 to 41 — a 70% increase in appointment bookings from the same $4,500 monthly budget
• Phone calls tracked: Previously unmeasured, now averaging 28 tracked calls per month from Google Ads (representing 68% of all ad-driven leads — confirming that phone tracking was the critical missing measurement)
• Click-through rate: Improved from 2.8% to 5.6% through better ad copy and extensions, reducing cost per click
• Quality Score: Average keyword Quality Score improved from 4.2 to 7.8, reducing cost per click by approximately 25%
• Wasted spend: Reduced from 38% of budget to under 8% through negative keywords and geographic targeting

The Business Impact

The financial impact extended beyond the PPC metrics. With cost per lead reduced by 40% and conversion volume up 70%, West Coast Dental's patient acquisition economics fundamentally changed. The practice went from questioning whether Google Ads was worth the investment to expanding their budget to $6,500 per month — confident that every dollar was generating measurable returns.

Dr. Chen summarised the impact: 'I went from dreading my marketing spend report to looking forward to it. Every month I can see exactly how many patients came from Google, what they searched for, and what procedures they booked. For the first time in my career, marketing feels like an investment rather than a gamble.'

Key Takeaways for Australian Healthcare Practices

West Coast Dental's experience highlights issues we see across the Australian healthcare sector. Medical, dental, and allied health practices are particularly vulnerable to poor PPC management because their service categories are diverse (creating keyword mismatch risk), their customers have high intent (making landing page quality critical), and phone calls represent the majority of conversions (making call tracking essential).

For any Australian healthcare practice running Google Ads, the non-negotiable foundations are: separate campaigns per service category, negative keyword lists that are updated monthly, dedicated landing pages matching every ad group's intent, call tracking on every campaign, and geographic targeting appropriate to your patient catchment. These fundamentals, properly implemented, will transform any underperforming healthcare PPC account.
