AEO Benchmarks

AEO Statistics and Benchmarks

If a number doesn't have a date, a source, and a scope, it isn't a benchmark. It's vibes. AEO is not a replacement for SEO, it is a co-performance problem, and you cannot defend budget with vibes. This is the data layer. Interpretation lives in our AEO implementation guide.

House rules for every entry on this page:

• One metric, one value, one named source, one date
• No orphan stats, no rounded approximations where source resolution permits
• Quarterly refresh; entries outside a 12-month vintage are flagged for re-sourcing

Two definitions to set before the data. "AI citation rate" means the share of qualifying pages cited at least once in a named answer engine's response. "AI-source referral" means a click to a tracked domain attributed to an answer engine in analytics.

Methodology

This hub catalogs 18 benchmarks compiled from primary sources: Semrush, First Page Sage, SEO.com, WordStream, Forge and Smith, and The Starr Conspiracy's proprietary AEO Readiness Assessment, SEO-AEO co-performance analysis, and client program data. Data collection window is January 2024 through September 2025. Every entry is a complete attribution unit: specific value, named source, publication or collection date.

Page schema is Article plus ItemList with Observation. Each benchmark is an Observation with measuredValue, measuredProperty, observationDate, and sourceOrganization. No FAQ schema, no DefinedTermSet, no HowTo schema is applied on this page.

Starr data sources

All Starr client results are reported in aggregated, anonymized form. No client domains or names are disclosed.

Respondent composition, AEO Readiness Assessment

Verification

• Each third-party stat cross-checked against the source page for value, date, and methodology
• De-duplication across overlapping studies before inclusion
• Date validation against the original publisher; if only year is published, year is used

Limitations

• Assessment sample skews toward B2B technology and SaaS; limited representation in financial services, healthcare, and industrial verticals
• Client implementation results vary by baseline technical health, category, and content inventory, and are not outcome guarantees
• Third-party benchmarks are reported as published; we do not re-run third-party studies

Refresh cadence

This hub is refreshed quarterly. Next refresh: Q1 2026. Entries outside a 12-month vintage window are flagged for re-sourcing or removal.
