AEO Benchmarks 2025

AEO Statistics and Benchmarks 2025

AI search referrals to B2B SaaS domains grew 800% year over year between July 2024 and July 2025, according to First Page Sage's July 2025 traffic analysis of identified AI-source referrals from ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini, measured across a rolling 12-month comparison window.

These are AEO benchmarks 2025: 18 dated, sourced metrics across five measurement categories, refreshed quarterly. 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.

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.
