Case study

+182% Organic Traffic: What We Actually Did

 ·  10 min read  ·  By Webmo

Case studies about SEO results are often either vague ("we improved their rankings!") or suspiciously perfect ("10x traffic in 30 days!"). This one is different. It's a detailed account of nine months of work with a medical practice in Brussels — the diagnosis, the strategy, the execution, the setbacks, and the actual numbers. Not to impress, but to be useful.

The context

The client is a multi-practitioner medical centre in the Brussels metropolitan area. They asked us to keep the name and specific commune anonymous — a common request in the healthcare sector. What we can say: four GPs, two specialists, a physiotherapist, and a reception team handling upwards of 80 appointments per day.

They came to us in June 2025 with a straightforward problem: their website received almost no organic traffic, yet they were fully booked months in advance through word of mouth and referrals from other practices. Their concern was growth — specifically, filling the availability of two new practitioners who joined the practice that spring.

The starting point (June 2025)

The diagnosis

Our initial audit identified three categories of problems:

Technical issues (critical priority)

The site was built on an outdated WordPress theme with 23 active plugins, many redundant or abandoned. Images were uncompressed JPEGs averaging 1.8MB each. There was no caching layer, no image delivery network, and render-blocking scripts in the <head> that delayed first paint by 4+ seconds. Additionally, several pages returned 404 errors due to a domain migration two years prior that was never properly redirected.

Content gaps (high priority)

The site had 6 pages: Home, About, Services (single page), Practitioners, Contact, and an empty Blog. No individual service pages, no FAQ content, no patient guides, no local landing pages. From a content perspective, the site gave Google almost nothing to index beyond business information.

Authority deficit (medium priority)

With only 12 referring domains — all from low-authority Belgian directories — the site had very limited authority in Google's eyes. No healthcare publications, no local media mentions, no professional association listings.

Phase 1 — Technical fixes (months 1–2)

We always start with technical SEO because content investment is wasted if Google can't crawl and index the site efficiently. The main interventions:

Result after month 2: PageSpeed mobile score improved from 34 to 81. First 3-pack appearance for "médecin généraliste [commune]" — position 3.

Phase 2 — Content strategy (months 2–6)

With the technical foundation solid, we moved to the content strategy. The medical sector has particular characteristics that shaped our approach: high E-E-A-T requirements (Google applies its strictest quality standards to medical content), a bilingual audience (French and Dutch), and a local search focus.

Service pillar pages

We created individual pages for each service offered: general practice, cardiology consultation, physiotherapy, paediatrics, preventive medicine, travel medicine. Each page: 800–1,200 words, practitioner credentials prominently featured, FAQ section (10–12 questions), Schema.org markup, internal links to related service pages and the appointment booking system.

Patient information blog

We launched a blog publishing one article per week targeting informational queries: "how to prepare for a blood test", "what is a Holter monitor?", "when should I see a GP vs. a specialist?", "understanding your cholesterol results". These articles aren't sales tools — they're genuine patient guides written with the practitioners' input and reviewed for medical accuracy.

The logic: these informational queries have search volume, low competition, and bring in exactly the right audience — people with health questions who are local to the practice. They also signal to Google that the site is authoritative on medical topics, which lifts the ranking of the commercial service pages by association.

Local landing pages

We created a dedicated page for each of the four main communes the practice serves. Each page: ~600 words of genuinely local content (distances, transport links, local health context), embedded Google Map, schema markup with specific address, reviews specific to that commune where possible.

A lesson learned the hard way: Our first draft of the commune pages was too templated — essentially the same text with the neighbourhood name swapped. Google's quality raters noticed (the pages saw minimal ranking improvement). We rewrote each page with genuinely unique local content. The second version performed significantly better.

Phase 3 — Authority building (months 4–9)

We ran link-building and content production in parallel from month 4 onwards. The link-building strategy for healthcare has to be conservative and quality-focused — spammy links in YMYL verticals can trigger manual penalties.

Earned links

Results month by month

Here's how the traffic evolved over the 9-month period:

Wait — that last number looks wrong. Month 9 shows a drop? Yes. A website redesign launched by the client's internal team in month 8 — without informing us — broke several redirect chains and temporarily deindexed some pages. We resolved it within 3 weeks, but the month 9 average reflects that disruption.

The clean comparison: June 2025 (420 sessions) vs. the pre-redesign peak in month 8 (1,680 sessions) = +300%. The 9-month average gives us +182% across the full period.

The conversion impact: Beyond traffic, the practice reported a 67% increase in online appointment bookings over the period. The two new practitioners filled their schedules within 4 months — the original business objective was achieved by month 6.

Key lessons

Technical SEO first — always

The single highest-impact action in the entire campaign was fixing page speed. It improved both the user experience and the crawl efficiency. Content investment before technical foundations are solid is money partially wasted.

Content quality matters more than content volume

In YMYL verticals (health, law, finance), Google's quality bar is high. One well-researched, practitioner-reviewed 1,200-word guide outperforms five generic 400-word articles. We published one article per week rather than three, and invested the time difference in quality.

Never let client teams touch the site without coordination

The month-8 redesign taught us a lesson we now build into every contract: a deployment checklist that must be followed before any site changes go live. The 3-week disruption cost the client more in missed bookings than the three months of additional SEO work we needed to do to recover.

Local SEO and content SEO reinforce each other

The Google Business Profile optimisation delivered immediate local 3-pack visibility. The content strategy delivered long-tail organic rankings. Together, they covered different parts of the search landscape — and the authority built by the content work also strengthened the local results.

Conclusion

This case study isn't a template. Medical SEO has its own characteristics — YMYL requirements, professional credential signals, bilingual content needs — that don't apply to every sector. What does apply universally is the underlying approach: diagnose before prescribing, fix the foundation before building on it, create content that genuinely serves the audience, and build authority through real relationships and real value.

SEO is not a shortcut. It's a compounding investment. The businesses that understand this and commit to it consistently are the ones that build sustainable, algorithm-resistant organic traffic — while their competitors scramble to adapt to every Google update.
