Website speed isn't just a UX problem — it directly affects revenue, SEO ranking, and user trust.
Google's research: 53% of mobile users abandon a site that takes more than 3 seconds to load. Amazon found every 100ms of latency costs 1% in sales.
I built a benchmarker that measures real-world performance metrics for any list of URLs: DNS resolution time, time to first byte, and total response time.
Results from running it against 12 UK business websites:
→ Fastest: under 200ms total
→ Slowest: over 3 seconds
→ Average: around 800ms
The slowest sites weren't small businesses. They were established brands. Speed is often an afterthought until it shows up in the analytics.
Built in Python. Outputs a ranked leaderboard with colour-coded speed bars. Useful for competitive analysis, pre-launch audits, or just satisfying curiosity.
