APEX Calculus
What this score means
Your AEO score measures whether AI search engines (ChatGPT, Claude, Perplexity, Gemini) can actually read your site and cite it in answers. Two-thirds of websites are invisible to them. APEX Calculus just got measured.
4/10 means APEX Calculus is borderline visible. AI bots can crawl your site but your structured-data signals are thin. You are at risk of being skipped when buyers ask AI for a recommendation.
About APEX Calculus
APEX Calculus is an open source calculus text, sometimes called an etext. Available in print and in .pdf form; less expensive than traditional textbooks.
