✔ +40% Patient Enquiries
✔ CPL ~€5
✔ 50+ Enquiries / Month
About The Client
The client is a regional aesthetic and beauty clinic in Germany, offering treatments such as:
- Botox & fillers
- Skin treatments
- Laser procedures
The primary goal was to generate a consistent flow of high-quality patient enquiries while maintaining a scalable and cost-efficient acquisition model.
The Challenge
The account faced several challenges typical for aesthetic clinics:
1. High competition in local markets
Keywords like Botox, fillers, and laser treatments are highly competitive and expensive.
2. Low-quality traffic from broad targeting
Previous campaigns attracted users with low purchase intent.
3. Trust-based conversion barriers
Patients require high trust before booking treatments.
4. Limited organic visibility
The clinic had low rankings for key treatment-related search queries.
Strategy: Full-Funnel Lead Generation System
The strategy was built around a structured, full-funnel approach combining high-intent demand capture, long-term organic visibility, and conversion-focused landing page optimization.
- Conversion Optimization → Improved user experience and trust signals to increase booking rates
- Google Ads → Captured high-intent search demand from users actively seeking treatments
- SEO → Strengthened long-term visibility, credibility, and organic traffic growth
Together, these elements created a scalable system that not only increased lead volume but also improved lead quality and overall campaign efficiency.
Google Ads Strategy
The Google Ads strategy focused on capturing high-intent demand from users actively searching for aesthetic treatments and consultations.
Campaigns were structured around treatment-specific and local search intent, supported by continuous keyword refinement, search term filtering, and negative keyword optimization.
Performance Max campaigns were used to expand reach, support remarketing, and improve efficiency across additional Google channels.
This structure helped improve traffic quality, strengthen intent matching, and generate more qualified patient enquiries over time.
SEO Strategy
SEO efforts focused on building long-term organic visibility and reinforcing trust across the clinic website.
Key work included optimizing treatment and service pages, improving local keyword relevance, strengthening internal linking, and refining on-page structure for both users and search engines.
Informational and service-focused content helped capture users researching treatments while also improving the clinic’s overall credibility and organic discoverability.
This supported paid campaigns by improving brand visibility, trust signals, and long-term lead generation stability.
Conversion Optimization (CRO)
Conversion optimization focused on turning more website visitors into qualified patient enquiries by improving the overall user journey.
Key improvements included clearer consultation-focused calls to action, stronger trust elements such as reviews and treatment information, improved landing page clarity, and a smoother mobile experience.
Reducing friction in enquiry and booking flows helped improve conversion rates across both paid and organic traffic sources.
This ensured that increased visibility translated into stronger booking intent and more efficient lead generation.
Results & Performance Metrics
Over the 6-month campaign period, the combined strategy of Google Ads, SEO, and conversion optimization produced measurable improvements in both patient enquiry volume and overall campaign efficiency.
Monthly enquiry volume increased steadily, while cost per lead remained within a controlled and efficient range despite scaling activity.
Continuous optimization of keyword targeting, bidding strategies, landing pages, and search term filtering contributed to stable and predictable growth.
Key performance improvements included:
✅ +40% increase in qualified patient enquiries
✅ Reduced cost per lead through improved targeting and optimization
✅ Conversion rates reaching ~12–15% in high-intent segments
✅ Consistent monthly enquiry generation with scalable growth potential
✅ Strong contribution from Performance Max and remarketing campaigns
Lead growth compares the initial baseline phase with optimized campaign performance across the remaining months.
Campaign Spend & Traffic Trends
During the first phase of the campaign, budgets were kept controlled to establish a reliable performance baseline and gather sufficient data.
As optimization progressed:
- Traffic from high-intent treatment searches increased steadily
- Campaign efficiency improved through better keyword and audience targeting
- Budget allocation shifted toward the best-performing segments
Unlike traditional seasonal industries, demand remained relatively stable, with performance fluctuations primarily driven by optimization cycles rather than external seasonality.
Despite increased budgets during scaling phases, traffic quality remained strong and overall campaign efficiency was maintained.
📊 Google Ads Campaign Performance (6-Month Period)

Conversions & Cost Per Lead
Patient enquiry volume increased significantly as campaign targeting, landing page alignment, and retargeting strategies were improved.
High-intent treatment campaigns delivered the strongest performance, while broader campaigns contributed additional reach and volume.
Performance Max campaigns further improved efficiency through:
- Cross-channel visibility
- Remarketing
- Audience expansion
Even with increased traffic and scaling budgets, cost per lead remained stable and efficient, indicating that improvements were driven by better targeting and conversion optimization, not just increased spend.
Improved conversion rates also demonstrate stronger alignment between:
- Landing page experience
- User intent
- Ad messaging
Special focus was placed on isolating high-intent treatment queries (e.g. Botox, fillers, laser treatments), which consistently delivered the highest conversion rates and lowest cost per enquiry.

SEO Impact on Performance
In parallel with paid campaigns, SEO improvements played a key role in strengthening long-term performance and trust.
Key SEO contributions:
- Optimization of treatment-specific service pages (Botox, fillers, skin treatments)
- Improved local search visibility for high-intent queries
- Better internal linking and content structure
- Enhanced on-page relevance and technical performance
SEO supported the overall strategy by:
- Increasing organic visibility
- Strengthening brand credibility
- Improving conversion readiness of users before they clicked ads
This created a stronger foundation for both paid and organic lead generation.

Conversion Optimization (CRO) Impact
Conversion rate optimization was a critical factor in improving campaign efficiency and turning traffic into qualified patient enquiries. In aesthetic markets, where trust and perceived expertise are critical, even small improvements in trust signals and page clarity had a disproportionate impact on conversion rates.
Key CRO improvements included:
- Clear consultation-focused call-to-actions
- Strong trust signals (reviews, credentials, treatment explanations)
- Improved landing page structure and readability
- Mobile-first optimization
- Reduced friction in enquiry forms
These changes significantly improved conversion rates and ensured that increased traffic translated into real enquiries and bookings, not just clicks.
