Get weekly uptime + AI visibility reports
Our monitoring tracks 25+ signals including uptime, speed, security, and AI mentions — with weekly email reports and alerts.
Why this matters
AI can't recommend a dead site
If your site is down when ChatGPT or Perplexity crawls it, you're invisible. Uptime is the foundation of AI visibility — everything else depends on your site being accessible.
Speed affects rankings
Slow response times hurt Google rankings and make AI crawlers timeout. A fast site means more crawled pages, more indexed content, and better AI understanding of your product.
Instant diagnostics
See HTTP status, response time, server type, SSL status, and key headers in one click. Know immediately if the problem is your server, DNS, or SSL certificate.

Frequently Asked Questions
How does the website status checker work?
We send an HTTP request to the URL from our servers and measure the response. We check the HTTP status code, response time, SSL certificate, and key response headers. If the site returns a 200 OK status, it's up.
Does uptime affect AI visibility?
Yes! If your site is down when an AI crawler visits, it can't index your content. Frequent downtime means less content for AI to learn from. AI assistants can only recommend products they can access and understand.
What HTTP status codes mean my site is down?
Status codes in the 5xx range (500, 502, 503) indicate server errors — your site is down or misconfigured. 4xx codes (404, 403) mean specific pages are broken. Only 2xx codes (200, 201) mean everything is working correctly.
What is a good response time?
Under 200ms is excellent. 200-500ms is good. 500ms-1s is acceptable. Over 1 second is slow and may cause AI crawlers to timeout or deprioritize your content. Google also uses page speed as a ranking factor.
Why might a site be down for me but not others?
Could be DNS issues, regional CDN problems, your ISP blocking the site, or local network issues. Our checker tests from our server location, so if it shows 'up' but you can't access it, the issue is likely on your end or regional.
How often should I check my website status?
For production sites, you should have continuous uptime monitoring (not just manual checks). Our AI visibility monitoring includes uptime checks as part of the weekly scan — if your site goes down, it affects your AI visibility score.
