How fast does your site respond?

Paste a URL. SiteAudix measures TTFB, payload, SSL, blacklists, caching, SEO tags and security headers — from the server, without guesswork.

Website speed, SSL and blacklist test

SiteAudix fetches the page from the server and scores TTFB, payload, compression, SEO tags and security headers. Use it to catch slow first bytes, missing HTTPS and weak crawler markup before users do.

Each run inspects the TLS certificate and checks the host against public DNS blacklists. Results include a performance meter and a comparison against popular sites.

Response time

TTFB and download of the document, including redirects.

Weight

HTML size plus estimated CSS, JS, images and fonts.

SSL & lists

Certificate validity plus Spamhaus, Spamcop, SURBL and URLhaus.
