XML Sitemap
Missing
Your website does not have an XML sitemap - this can be a problem for search engines.
An XML sitemap informs search engines about URLs available for crawling on your site. It includes information about your site's latest updates, frequency of changes and relative importance of each URL. This allows search engines to crawl the site more efficiently.
Robots.txt

Great, your website has a robots.txt file.

AI Search Readiness
AI Crawlers
AI search crawlers are allowed, so the site can be shown and cited in AI answers (ChatGPT, Claude, Perplexity).
|
OAI-SearchBot | ChatGPT search | AI search |
|
ChatGPT-User | ChatGPT (user requests) | AI search |
|
Claude-SearchBot | Claude search | AI search |
|
Claude-User | Claude (user requests) | AI search |

|
ClaudeBot | Anthropic training | AI training |
|
Google-Extended | Google Gemini training | AI training |
|
Applebot-Extended | Apple AI training | AI training |
|
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
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.
