GEO Strategy by Industry — Case Studies for Professional Services / Healthcare / Real Estate / B2B SaaS / E-commerce

• The tactics that move the needle in GEO differ by industry. Beyond the universal foundations like "deploy llms.txt," each industry has its own specific moves.
• This guide organizes strategies for five industries from observation data: professional services (tax accountants, lawyers, etc.) / healthcare and clinics / real estate / B2B SaaS / e-commerce.
• Regulations, audience characteristics, content strategy, and KPIs differ by industry. Sequencing the work incorrectly hurts ROI.
• Read the section for your industry and start by narrowing your 3-6 month moves to just 1-2 items.

The five industries covered in this guide, mapped on two axes — regulatory difficulty and AI search adoption — look like this:

1. Professional Services (Tax Accountants / Lawyers / Administrative Scriveners / Labor Consultants)

Industry characteristics

• Clients have a culture of matching via "area + specialization" searches.
• Examples: "Shibuya-ku startup financing tax accountant," "Minato-ku international inheritance lawyer."
• Retainer contracts dominate (high LTV, large allowable acquisition cost).
• Advertising rules (the Certified Public Tax Accountants Act, the Basic Rules of Professional Conduct for Attorneys, etc.) make "No.1 / industry's best"-style claims difficult.

AI search citation patterns

Patterns confirmed in GEO Meter's initial observations (the first ranking for the tax accountant industry, Shibuya-ku × startup financing):

• Four out of the top five firms were cited across all three AIs — ChatGPT, Claude, and Gemini.
• Service names that include "area + specialization" (e.g., "Shibuya Financing Support Office") also appear near the top.
• Public institutions (e.g., Japan Finance Corporation) are mixed into the top citations (recommended to exclude on the GEO tool side).

The cross-industry trend will continue to be verified as the observation footprint expands.

GEO strategy priorities

1. Consider including keywords in the firm name or brand name (for new openings).
2. Build out "case study pages" and "FAQ pages" (direct drivers of citation acquisition).
3. Publish information on local partnerships (chamber of commerce ties, tax office cooperation, etc. — original information).
4. Third-party media exposure (tax-accountant comparison sites, professional services portals).

Priority tactics (3-6 months)

Regulatory notes

• The Certified Public Tax Accountants Act and the Basic Rules of Professional Conduct for Attorneys prohibit "exaggerated claims of achievements," "comparisons against other firms," and "unclear fee disclosure."
• Exaggerated content written purely to attract AI citations carries legal risk.
• Sticking to objective facts (representative's biography, actual case counts, etc.) is the safe approach.

2. Healthcare / Clinics

Industry characteristics

• Patients and consumers search by "area + symptom / specialty."
• Examples: "Shibuya-ku acne dermatology clinic," "Aoyama orthodontist recommendations."
• Pre-visit information gathering is long (decision period: 2 weeks to 3 months).
• The Medical Advertising Guidelines (under the Medical Practitioners' Act) impose strong constraints on what can be said.

AI search citation patterns (expected)

• "Doctor biographies," "credentials held," and "track record (e.g., number of surgeries)" are strong citation sources.
• Patient testimonials and case photographs are constrained by the Medical Advertising Guidelines, so their AI citation rate is low.
• Third-party media (hospital search portals, etc.) tend to land at the top of citations.

GEO strategy priorities

1. Strengthen doctor biography pages (credentials, board certifications, academic society memberships).
2. Build out pages for treated conditions / therapies (each condition on its own page).
3. FAQ pages (officially clarify "fee structure," "insurance coverage," "side-effect risk," etc.).
4. Links from official and quasi-official sites (medical associations, board certification bodies, etc.).

Priority tactics (3-6 months)

Regulatory notes

• Under the Medical Advertising Guidelines (effective 2018-):
  • Strong constraints on language about treatment outcomes (e.g., "guaranteed to cure" is prohibited).
  • Patient testimonials, reviews, and case photographs are in principle prohibited (limited exceptions exist).
  • "Industry No.1" / "the best in the field" expressions are prohibited.
• Using any of the above purely to attract AI citations carries extremely high legal risk.
• For medical corporations, designate an advertising compliance officer and build a pre-publication review process.

3. Real Estate

Industry characteristics

• Area-based search dominates ("Musashi-Koyama used condo," "Setagaya-ku detached house for rent").
• Decisions are made per property (high price, low frequency).
• Specific labeling rules for the real estate industry (regulations of the Real Estate Fair Trade Council Federation).
• Strong influence from local media and local information sites.

AI search citation patterns (expected)

• "Area information," "school districts," and "transit access" are strong citation sources.
• "Area guides" tend to be cited by AI more than individual property pages.
• Backlinks from industry-wide or regional media flow directly into the Diversity score.

GEO strategy priorities

1. Build out area guide articles (stations, school districts, parks, commercial facilities — comprehensive).
2. Property type pages (sales / rental / investment / corporate).
3. Strict adherence to industry-mandated labeling (e.g., "X minutes' walk," "year built" — precise notation).
4. Guest contributions to local media (article supply to local news outlets, town magazines, etc.).

Priority tactics (3-6 months)

Regulatory notes

• Under the Real Estate Fair Trade Council Federation rules:
  • Strict accuracy obligations for property representations (1 minute walking = 80 meters; walking time of 5 minutes or more must be the actual measurement, etc.).
  • Prohibition of bait advertising (e.g., leaving sold properties in listings).
  • Restrictions on superlative expressions like "bargain" or "great deal."
• Fudging any of these to attract AI citations creates Premiums and Representations Act (景品表示法) violation risk.

4. B2B SaaS / IT Services

Industry characteristics

• Buyers (corporate DX leads and IT departments) have extremely high AI search adoption.
• "Vendor comparison" and "category recommendations" queries occur constantly.
• Examples: "sales SaaS comparison," "HR system recommendations," "accounting automation vendors."
• Evaluation period: 1-6 months, with multi-stakeholder decisions.

AI search citation patterns (expected)

• "Official site / documentation" carries high trust.
• "Comparison articles / review articles" appear frequently as citation sources.
• Reviews on third-party media (ITreview, Capterra, G2, etc.) directly affect Sentiment.
• "Industry-specific case studies" are major drivers of citation acquisition.

GEO strategy priorities

1. Build out official docs and API reference (engineer-facing).
2. Industry-specific use case collections (vertical expansion like "for construction").
3. Engage with comparison articles (document clear differentiation vs competitors).
4. Earn ratings on third-party review sites (ITreview, etc.).

Priority tactics (3-6 months)

Regulatory notes

• Comparison tables against competitors require "objective facts" + "publicly available sources."
• Writing that a competitor "lacks" a feature when it actually has it carries Unfair Competition Prevention Act risk.
• Superlative claims like "industry-best" or "overwhelming" should be handled with care under the Premiums and Representations Act.

5. E-commerce / D2C

Industry characteristics

• Consumer AI search adoption is expanding rapidly.
• Typical queries: "best ○○," "○○ ranking," "○○ comparison."
• Segmentation by product category × persona is essential.
• Heavy reliance on review and rating data.

AI search citation patterns (expected)

• "Comparison articles" and "ranking articles" dominate citations.
• "Category top pages" and "guide pages" are cited more than individual product pages.
• Third-party review site ratings (価格.com (Kakaku.com — Japan's leading price comparison and review site), @cosme (At Cosme — Japan's largest cosmetics review platform), etc.) strongly influence AI.
• Number of reviews and average rating frequently appear as citation sources.

GEO strategy priorities

1. Correct implementation of Product Schema + AggregateRating (false data violates the Premiums and Representations Act).
2. Build out category top pages (turn them into guide articles).
3. Strengthen comparison content (objective comparison of own products vs competitors).
4. Earn authentic third-party reviews and SNS word-of-mouth.

Priority tactics (3-6 months)

Regulatory notes

• Premiums and Representations Act:
  • Falsified AggregateRating numbers constitute "misleading representation of superiority" (subject to administrative orders).
  • "No.1" / "industry-first" claims require survey evidence from a research firm (also linked to the Antimonopoly Act).
  • Stealth marketing regulation (effective 2023-): promotion disguised as third-party content is prohibited.
• Padding the data to chase top AI ranking is fatal.

6. Cross-Industry Checklist

Before moving to industry-specific strategy, confirm the universal foundations. This flow is the efficient order in which to start:

• Is llms.txt deployed at the root?
• Is Schema.org (Organization + Service / Product) implemented?
• Are 10 or more FAQ pages in place?
• Are AI crawlers (GPTBot / ClaudeBot, etc.) Allowed?
• Is a monthly AI search observation process in place?
• Is there a process for complying with industry regulations (advertising guidelines, etc.)?
