AI Search Readiness
AI Crawlers
AI search crawlers are allowed, so the site can be shown and cited in AI answers (ChatGPT, Claude, Perplexity).

CCBot | Common Crawl | AI training |
Blocking AI training crawlers is a common choice and doesn't affect the score. Only the AI search crawlers count.
Structured Data
No schema.org structured data found. Adding it (for example Organization, WebSite or Product in JSON-LD) helps search engines and AI tools understand the page and can enable rich results.
Canonical Tag
No canonical tag found. Add <link rel="canonical"> so search engines know which URL is the main version and don't split ranking between duplicates.
llms.txt
No llms.txt file. It's an emerging convention: a short Markdown summary of the site for AI tools. Optional, so it doesn't affect the score.
Security
HTTPS
The site loads over HTTPS, so connections are encrypted. Browsers and search engines expect this.
HSTS
The site sends a Strict-Transport-Security header, so browsers always use HTTPS for it.
Security Headers
1 of 5 common security headers found. At least 2 are needed to pass.
