How to Fix Slow Mobile Pages in Under an Hour
Mobile performance is usually a few repeatable issues: oversized images, too much JavaScript, layout shifts, and a hero section that asks the browser to do too much too early.
Fast wins
- 1. Compress the biggest images and convert them to AVIF/WebP.
- 2. Delay non-essential scripts until after the first visible paint.
- 3. Use a single CTA in the hero and keep the form short.
- 4. Remove layout jumps by giving media and cards fixed dimensions.
- 5. Keep the page layout column-based on narrow screens.
Image hygiene
The biggest wins often come from shrinking hero media and replacing unnecessary screenshots.
Script hygiene
Client-side code should be reserved for the parts of the page that truly need it.
Spacing hygiene
Avoid massive vertical gaps that push conversion elements below the fold on phones.
CTA hygiene
Make the call to action visible without scrolling or pinching.
