Website Speed Checker
Real-Time Execution Engineπ How to Use This Tool
- Enter your complete website URL (including https://).
- Click 'Run Website Speed Checker Analysis'.
- Our server executes a real cURL query measuring connection milestones.
- Review TTFB, SSL handshake duration, and speed score recommendations.
β What This Tool Analyzes / Generates
Measures DNS lookup duration, TCP connection time, SSL handshake latency, Time to First Byte (TTFB), total transfer time, HTTP response status code, and payload compression.
β What It Does NOT Check
Does not execute client-side JavaScript single-page-app rendering or simulate multi-device visual rendering (use Lighthouse or Core Web Vitals auditor for DOM visual metrics).
βοΈ Technical Implementation & Best Practices
Search engines prioritize fast-responding servers. A TTFB under 200ms ensures web crawlers can efficiently crawl and index your web pages without timeouts.
β Frequently Asked Questions
What is considered a good TTFB for modern websites?
Google recommends a TTFB of 200ms or lower for optimal search engine crawling and high user conversion rates.
How does server speed affect SEO rankings?
Server latency directly impacts Core Web Vitals (specifically Largest Contentful Paint) and crawl budget allocation on large websites.
Why does TTFB fluctuate between test runs?
Fluctuations can occur due to server cache warming, edge CDN routing, transient network congestion, or background database queries.
