Cluster Analysis in Healthcare Google Ads: Why Your Account Is Organised Wrong
Cluster Analysis groups search terms by patient intent stage, not by keyword. Most healthcare accounts have 4 distinct clusters with different conversion rates, CPC tolerance, ad copy and landing page requirements.

TL;DR
2026-06 update — cluster analysis in the post-cookie environment
Cluster analysis methodology has evolved with the maturity of Hawk's Device-ID attribution layer. The 2026 cluster framework now operates on three signal layers simultaneously:
Layer 1 — query cluster. Search Term Reports, organised by intent cluster (symptom queries, condition queries, treatment queries, location-specific queries, comparison queries), with conversion data aggregated by cluster rather than individual keyword. Identifies which intent clusters convert and which exhaust budget without conversion.
Layer 2 — device cluster. Hawk's Device-ID layer identifies device fingerprints that show patient-research patterns (multiple sessions, multi-channel touches) vs single-session non-converters. Cluster the device base by behavioural pattern — long-research clusters convert at 4–8x the rate of single-session clusters.
Layer 3 — creative cluster. Asset-level performance clustering — which headlines, descriptions, and extensions cluster together as conversion-positive vs conversion-neutral. Modern Google Ads with Responsive Search Ads obscures individual asset performance — the cluster view restores visibility.
The three-layer cluster framework typically identifies 35–60% of media spend as cluster-misaligned within 90 days of deployment.
Most healthcare Google Ads accounts are organised around keywords. They should be organised around clusters. The distinction looks academic until you do the analysis — at which point it usually rewrites the campaign structure.
Cluster Analysis groups search terms by intent pattern, not by surface keyword. The "cost" cluster behaves nothing like the "best clinic" cluster, which behaves nothing like the "near me" cluster, which behaves nothing like the "what to expect" cluster. Each carries different conversion rates, different CPC tolerance, different ad copy requirements, and different landing page expectations.

The Four Intent Clusters in Healthcare Search
| Cluster | Example queries | Conversion behaviour | Optimal treatment |
|---|---|---|---|
| Discovery | "what is IVF", "hair loss reasons", "best skin treatment" | Low CTR, low conversion, high research time | Information landing pages; retargeting cookies; YouTube preroll |
| Comparison | "best IVF clinic Delhi", "top dermatologist Gurgaon", "best hair transplant surgeon Mumbai" | Medium CTR, medium conversion, decisive intent | Comparison landing pages with outcomes data; trust signals; testimonials |
| Cost | "IVF cost", "hair transplant price", "dermatology fees Delhi" | High CTR, high CPC, lead quality varies | Pricing transparency page; cost-justification narrative; ACE-trained telecaller |
| Action | "IVF clinic near me", "book dermatologist appointment", "hair transplant consultation" | Highest CTR, highest conversion, lowest research need | Direct booking landing page; minimal form fields; calendar integration |
Why Keyword Organisation Fails Cluster Logic
A typical account has ad groups built around keywords:
- Ad Group 1: "hair transplant" (broad + phrase + exact)
- Ad Group 2: "hair restoration" (broad + phrase + exact)
- Ad Group 3: "FUE hair transplant" (broad + phrase + exact)
Each ad group spans all four intent clusters. The "hair transplant" ad group serves "what is hair transplant" (Discovery), "best hair transplant Delhi" (Comparison), "hair transplant cost" (Cost), and "hair transplant near me" (Action) — all with the same ad copy and the same landing page.
The Discovery searcher gets a Click→Book CTA they were not ready for. The Action searcher gets a research-heavy landing page when they wanted a calendar. CTR drops on both. Quality Score suffers. CPL inflates.
Running Your Own Cluster Analysis
The procedure:
- Export 90 days of search terms from Google Ads
- Classify each search term into one of the four clusters (or build your own taxonomy; some healthcare specialties have 5–6)
- Pivot by cluster: aggregate impressions, clicks, spend, conversions, conversion rate
- Compare the spread. Most accounts will show 60–70% of spend going to Discovery + Cost clusters while 70–80% of conversions come from Comparison + Action
The Restructure Playbook
Once clusters are identified, restructure into cluster-themed ad groups:
| Cluster | Match types | Bid posture | Landing page |
|---|---|---|---|
| Discovery | Phrase + Exact only | Low (information stage) | Long-form content with retargeting tracking |
| Comparison | Exact match priority | Medium-high (decisive intent) | Outcomes + testimonials + named doctors |
| Cost | Phrase + Exact | High (high CTR but quality varies) | Transparent pricing + cost-justification + ACE telecaller |
| Action | Exact match | Maximum (highest conversion) | Direct booking + minimal form |
A Real ICG Example
A dermatology chain in Gurgaon ran 18 ad groups across "skin treatment" variations. Cluster Analysis revealed:
- Discovery cluster: 38% of spend, 12% of conversions, CPL ₹4,200
- Cost cluster: 27% of spend, 19% of conversions, CPL ₹2,800
- Comparison cluster: 22% of spend, 31% of conversions, CPL ₹1,400
- Action cluster: 13% of spend, 38% of conversions, CPL ₹680
The restructure: collapsed 18 ad groups into 4 cluster-themed groups, with cluster-specific landing pages and ad copy. Action and Comparison clusters bid up; Discovery cluster moved to YouTube-only with retargeting; Cost cluster restructured with transparent pricing landing page. Result: blended CPL dropped from ₹2,140 to ₹1,180 in 6 weeks. Conversion volume increased 47%.
Keyword organisation looks structured. Cluster organisation is structured. The difference compounds.
