Design for 3G, not fiber.

Most clients live on slow mobile data at least once a day. Your site needs to load there. Here's how to test it honestly.

This piece dives into the practical mechanics of what the headline says — built around three things I've shipped in the last six months.

The three key takeaways

  1. Throttle in DevTools is honest.
  2. Real device > emulator.
  3. Visit your own site on a train ride.

For the full version with code samples, screenshots from shipped sites, and the specific files I send to clients, email me. I send the working file to anyone who asks — no signup wall, no newsletter ransom.

Want this applied to your site? It's part of every Production package ($5,000).

Why I wrote this

Most posts about this topic are written by people selling a product. I'm selling time — I get paid to ship sites, not to keep you reading. So the version on this page is the short, useful one. The expensive version is me applying it to your codebase.
