Why does it vary by industry?
LLMs do not answer every question with the same criteria. Medical questions prioritize medical authority; product recommendations prioritize user reviews; B2B SaaS questions prioritize real use cases. The same principles (answer-first, structured data, E-E-A-T) apply, but which signals carry more weight differs by industry.
BrightEdge's industry-level AI Overview appearance rates as of February 2026 make the gap clear.
| Industry | AI Overview appearance rate | AEO priority |
|---|---|---|
| Healthcare | ~88% | Very high |
| Education | ~83% | Very high |
| B2B Tech/SaaS | ~82% | Very high |
| Restaurants | ~78% | High |
| Insurance | ~63% (17% one year ago) | High |
| Entertainment | ~37% | Medium |
| Travel · E-commerce · Finance | Other | Medium |
| Local services | ~7% | Low (Map Pack first) |
Healthcare, education, and B2B tech should start AEO now. Local businesses still rely heavily on traditional local SEO and Google Business Profile.
Industry framework — 5 groups

One company can span multiple groups. A medical clinic is YMYL + Local; a medical e-commerce site is YMYL + E-commerce; B2B healthcare SaaS is YMYL + B2B SaaS. You need signals from every group you belong to for citation rates to rise.
1. YMYL industries (healthcare · legal · finance · insurance)
YMYL (Your Money Your Life) covers content that directly affects users' health, finances, or legal rights. Healthcare sees AI Overviews in ~88% of searches, and roughly 25% of ChatGPT's weekly active users ask health-related questions (OpenAI data). This is where AI answers work most often.
5 key signals
Author credentials
Medical license numbers, bar membership, financial certifications (CFP, CFA, etc.) clearly stated
Institutional certification
Hospital accreditation, law firm registration, financial license information
Primary sources
Direct citations of academic papers, government/public agency data, clinical guidelines
Update frequency
Perplexity shows lower citation rates for medical content older than 60–90 days.
Disclaimer
Clearly distinguish general information from diagnosis or professional advice.
Regulations are tightening trust requirements for medical and financial content. Disclosing AI use and review processes on content will likely become a trust signal going forward.
Example: "Reviewed by Dr. [Name], internal medicine specialist, license #[number]" cites better than a generic "medical team review."
2. Local business (clinics · retail · F&B · services)
Local search is an exception in AEO. AI Overview appearance stays around 7%, and Google still prioritizes the Local Map Pack (map + business cards) for local queries.
5 key signals
NAP consistency
Name, Address, and Phone must be identical across your website, Google Business Profile, Yelp, and other local directories.
Structured business hours
Fill the openingHours field in LocalBusiness schema accurately.
Reviews
Google, Yelp, and industry-specific review platforms are trust signals that AI cites directly.
Explicit location names
"Downtown dental clinic on Main Street" is more precise than "city dental clinic" for local signals.
Category accuracy
Your primary category in Google Business Profile is decisive for visibility.
Local market note: Google Business Profile and major local directories still drive most discovery. Make your site AEO-friendly while keeping profile accuracy and review response rates in sync.
3. E-commerce
E-commerce has a complex relationship with AI answers. Informational comparison queries ("Which is better, X or Y?") land in AI Overviews, but transaction queries ("Buy X") still favor search and shopping ads. Commercial query AIO share has risen from 6% to 19% in a year—hard to ignore.
5 key signals
Product schema
Price, stock, ratings, and review counts must be specified in structured data.
Review content
Text reviews—not just star ratings—become citation signals for LLMs.
Comparison content
"[Product A] vs [Product B]" comparison content has the highest AI Overview citation rates.
Use cases
Include concrete scenarios: who uses it, when, and how.
External review sites
Mentions on Wirecutter, Consumer Reports, and major shopping review platforms act as signals.
Data to note: E-commerce traffic from ChatGPT recommendations converts and earns less per session than Google search and ads (Kaiser & Schulze 2025). AI citations work well for awareness and consideration, but the path to purchase is longer. Treat AI citations as a long game.
4. B2B SaaS
B2B SaaS has among the highest AEO priority alongside healthcare. AI Overview appearance is ~82%, and ~84% of B2B decision-makers use AI tools during purchase evaluation (Wynter 2026 — up from 24% a year ago). Forrester reports ~94% of B2B buyers use AI search. The first screen in the decision process is increasingly an AI answer.
5 key signals
Case studies
Case studies with customer name, industry, and specific results (numbers) are the strongest signal.
G2 and review sites
G2 is the #1 cited domain for SaaS category LLM citations.
Comparison content
"vs competitor" pages are especially favorable for ChatGPT citations.
Integration info
Specify concretely which tools your product connects with.
Technical documentation
API docs and integration guides demonstrate deep expertise as citation signals.
One important insight: ChatGPT tends to cite direct competitors together in B2B categories (Profound 2026). Honest comparison content—"us for this case, competitor for that case"—gets cited more often than "we are superior in every way."
5. Info & media
News, magazines, blogs, and research firms face the fiercest LLM citation competition. ~85% of AI Overview cited content was published within the last two years, and Perplexity's citation rate drops quickly for content older than 60–90 days.
5 key signals
Original primary data
Statistics from your own surveys, polls, or analysis are assets no one else has.
Expert quotes
Quotes with real names, affiliations, and direct comments get cited more than anonymous quotes.
Update frequency
Refresh data, examples, and dates at least quarterly to maintain effectiveness.
Links to authoritative domains
Links to government, academic, and reputable media sources strengthen authority signals.
Methodology disclosure
A paragraph explaining how you measured or surveyed boosts trust.
The biggest risk here is publishing once and abandoning. Even a well-written article loses half its citation rate after six months. You need a quarterly refresh workflow.
Where does your company fit? — 5-question diagnosis
If you answer "YES" to any of these five questions, you must build that group's signals.
Does our content affect users' health, finances, or legal rights?
YES → YMYL
Is revenue driven primarily by customers visiting a specific location?
YES → Local
Do transactions happen at the individual product level?
YES → E-commerce
Do enterprise buyers evaluate our solution during their decision process?
YES → B2B SaaS
Is content itself a core business asset?
YES → Info & Media
Spanning multiple groups is normal. A medical clinic needs YMYL + Local; healthcare SaaS needs YMYL + B2B SaaS. Apply signals from every group you belong to.

Frequently asked questions
Q1. Our company spans multiple industries. Where should we start?
Start with the group that has the highest AI Overview appearance rate for the best ROI. If you span YMYL and B2B SaaS, fix those signals first. If local business is a large share, begin with Google Business Profile accuracy and local directory consistency.
Q2. Can local businesses mostly skip AEO?
You cannot ignore it entirely. AI Overview appearance is only about 7%, but users increasingly search "best dental clinic downtown" on ChatGPT or Perplexity. Build basic AEO signals on your site (answer-first structure, FAQ, JSON-LD), but keep local SEO as the priority.
Q3. Does YMYL like healthcare and legal work in practice?
Yes. Health-related questions make up a significant share of ChatGPT usage globally, and regulations increasingly require trust signals for medical and financial content. Stating credentials, primary sources, and update dates helps both compliance and AEO.
Q4. We are B2B SaaS but not listed on G2 or similar review sites.
For a US-first market, start with industry media reviews and interviews. If you also target global buyers, registering on G2 makes a major difference for ChatGPT and Perplexity citations.
Q5. Is AEO worth the investment for e-commerce?
Transaction queries still favor search and ads. But comparison queries ("Which is better, X or Y?", "Best X for beginners") are rapidly moving to AI Overviews. Focus AEO on comparison content and use-case scenarios for the best efficiency.
