Website Speed & SEO Checker
A server-side website analysis engine that probes any public URL and returns: HTTP response time, SSL certificate status, mobile viewport readiness, page title and meta description, resource counts (scripts, styles, images), security headers (HSTS, CSP, X-Frame-Options), and a calculated 0-100 performance score.
The Challenge
Building a reliable URL scanner that handles redirects, SSL edge cases, non-standard servers, and timeouts while extracting meaningful performance metrics from raw HTTP responses and HTML.
The Approach
Server-side fetch with AbortSignal timeout, HTTP header inspection for security grading, regex-based HTML meta tag extraction for SEO analysis, and a weighted scoring algorithm combining response time, SSL, mobile-readiness, and security headers.
The Result
A comprehensive website intelligence tool delivering instant performance, security, and SEO reports for any public URL — used by developers and marketers.
