Key Findings

Structured Data is the weakest category — the average website scores near 0% on schema markup for AI.
Meta Tags are widely neglected — most sites miss critical on-page SEO fundamentals.
AI Search Readiness lags far behind SEO — the average AISO score (36) is roughly half the average SEO score (62).
No site scored an A or A+ — there's massive room for improvement across every industry.
