What do you want to know about your site?
Select any question below to open a dedicated diagnostic checker. If you entered your domain above, we will automatically test it on the next page.
Is ChatGPT blocked from crawling my website?
Test live if GPTBot and OAI-SearchBot receive 200 OK or if your WAF/robots.txt blocks ChatGPT citations.
Why is Perplexity or Claude not citing my website?
Diagnose PerplexityBot and ClaudeBot edge access, /llms.txt presence, and structured entity grounding.
Does my website have a valid /llms.txt file?
Probe your root domain for /llms.txt, score its markdown structure, and check cited links for 200 OK reachability.
How do I generate an /llms.txt file for my website?
Crawl your top indexable pages and synthesize /llms.txt, /llms-full.txt, and a zero-JS entity HTML page.
Are my page keywords aligned with my Title, H1, and Meta Description?
Compute 1/2/3-word N-gram keyword alignment and verify whether top body phrases appear in your headings.
Will my page title or meta description get cut off in Google search?
Measure exact SERP pixel width (580px limit) on your live page or test a draft title before publishing.
