What is a good website response time?

A response time under 200ms is excellent; under 500ms is acceptable. Anything above 1 second can significantly impact user experience and SEO rankings.

TTFB (Time to First Byte) is the time from sending an HTTP request to receiving the first byte of the response. It measures server processing and network latency combined.

Can I test any website's response time?

Only publicly accessible websites can be tested. Private or firewall-protected endpoints may fail or return inaccurate results.
