pbslearningmedia.org registers just 10/100 on the ACRI scale — a bottom-tier result indicating systemic AI visibility problems. Within the infrastructure vertical, this places pbslearningmedia.org below the industry average of 57 —, indicating room for competitive improvement. A ghost ratio of 50% signals a rendering gap: a significant portion of page content requires JavaScript execution to become visible. Heavy markup overhead (44.7× bloat) forces AI systems to wade through excess code before finding useful information. The complete absence of JSON-LD schema is a missed opportunity: even basic Organization markup would improve how AI crawlers understand this domain. The site allows access to some AI bots but restricts others, creating an uneven visibility profile across AI-powered services.

📊 ACRI Sub-Scores (AI Readiness Detail)
pbslearningmedia.org punches above its weight in AI — AI visibility exceeds Google ranking. This is a competitive moat worth protecting. ACRI measures technical crawler readiness. Read the methodology →
Why pbslearningmedia.org ranks here
Fastest improvements
- Allow GPTBot in robots.txt so AI crawlers can access your pages (see Crawl Access).
- Add basic Organization and WebSite JSON-LD to fix “0 schema blocks” (see Schema Coverage).
- Reduce token bloat (navigation/footer/code) so agents reach your main content faster (see Token Bloat).
- Create an
llms.txtfile so AI crawlers can discover your content structure without heavy crawling. Generate llms.txt → - Run a full entropy audit to find which DOM regions waste the most tokens. Run Entropy Audit →
