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
No Strict-Transport-Security (HSTS) header. It tells browsers to always use HTTPS, which protects visitors from being downgraded to an insecure connection.
Security Headers
0 of 5 common security headers found. At least 2 are needed to pass.
