An AEO Index measures how prominently universities and programs appear in AI-generated answers across ChatGPT, Perplexity, Gemini, and Claude. It tracks mention frequency, listing position, platform consensus, and share of voice, giving institutions a data-driven view of AI visibility compared to competitors.
AEO Industry Index
Higher Education · March 2026
Harvard leads.
Wharton dominates volume.
The other five are competing for what's left.
Arcalea ran 60 prompts across ChatGPT, Perplexity, Gemini, and Claude to measure which M7 Business Schools appear in AI-generated answers, and how prominently. The results reveal a two-tier system, platform-level divergence, and a visibility gap that traditional SEO doesn't explain.

Who AI recommends
when applicants ask.
Composite score is a weighted blend of mention frequency, listing position, platform consensus, and share of voice. A higher score means stronger, more durable AI visibility across all four platforms.

Platform Intelligence
Each AI platform recommends
a different school.
Visibility on one platform does not predict visibility on others. A multi-platform measurement strategy is the only way to see the full picture.
ChatGPT
Platform Leader
Harvard + Columbia
218 total mentions
Columbia earns 43% of its total index mentions on ChatGPT alone, a single-platform dependency that creates fragility.
Claude
Platform Leader
Wharton + Kellogg
201 total mentions
Claude surfaces mid-tier programs more readily, with Yale SOM earning 9 mentions vs. 2 on ChatGPT.
Gemini
Platform Leader
Stanford + Harvard
177 total mentions
Gemini shows the strongest intermediary bias: ranking publications (FT, Bloomberg) appear frequently alongside schools.
Perplexity
Platform Leader
Wharton + Kellogg
171 total mentions
Perplexity shows the strongest position-power skew: fewer mentions, but listed higher. Berkeley Haas appears 8x vs. 2x on Claude.
Key Findings
What the data actually says.
Three findings that change how you think about AI visibility in higher education.
M3 + M4
The M7 is really two tiers, not one
Harvard, Wharton, and Stanford average a composite of 0.501. The remaining four average 0.408, a 9.3-point gap that doesn't close in any single category or on any single platform. Being in the M7 is not the same as winning in AI search.
FT > Yale
Ranking publications outcompete some schools
The Financial Times earns a composite of 0.331, higher than every extended school competitor and higher than Yale SOM. When AI engines respond to MBA queries, they often cite intermediaries rather than schools directly. The FT is effectively a competitor for AI attention.
Position > Volume
Being cited first matters more than being cited often
Harvard wins the composite ranking with fewer total mentions than Wharton because it almost always appears first. Position Power (0.919 vs. 0.832) is the deciding factor. Frequency without position is noise. Institutions should optimize for being named first, not named most.

Common Questions
AEO in higher education, explained
What is an AEO Index for higher education?
Which business school has the highest AI visibility?
In Arcalea's March 2026 M7 AEO Index, Harvard Business School holds the top composite score (0.506), with Wharton second (0.501) and Stanford GSB third (0.495). Wharton generates the most raw mentions, but Harvard wins on position power; it almost always appears first when cited.
How is AI search visibility different from traditional SEO for universities?
Traditional SEO optimizes for ranked results on Google. AI visibility (AEO) optimizes for being cited as the answer when a prospective student asks ChatGPT or Perplexity a question. The mechanisms are completely different: 47% of AI citations come from pages ranking below position five in traditional search.
Why do different AI platforms recommend different business schools?
Each AI platform has distinct training data, retrieval mechanisms, and ranking logic. ChatGPT favors Harvard and Columbia, Claude distributes more evenly with strong Kellogg performance, Gemini favors Stanford, and Perplexity shows the strongest position-power skew. Visibility on one platform does not predict visibility on others.
What is the biggest AEO opportunity for higher education institutions?
The biggest opportunity is in category-level AI queries: questions prospective students ask before naming a specific school, like "best MBA for finance" or "is an MBA worth it." Institutions that own these high-volume, high-intent queries through structured data and answer-first content capture prospective students before competitors enter the conversation.
How can a university improve its AI search visibility?
The highest-impact improvements are FAQPage schema on program pages, answer-first content architecture (leading with a direct answer in the first 40-60 words), original research that AI engines prefer to cite, and E-E-A-T signals (faculty credentials, outcomes data, third-party citations). Arcalea's AEO audit identifies exactly which signals are missing and prioritizes fixes by expected citation lift.
