In May 2025, I identified a gap in the market: most internet speed test tools were either bloated with ads, slow to load, or lacked proper SEO optimization. The dominant players (Speedtest.net, Fast.com) had massive brand recognition but poor organic search optimization.
I saw an opportunity to build a completely free, lightning-fast speed test tool that could rank organically for thousands of speed-related keywords and provide genuine value to users without aggressive monetization.
