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 — do these first
- 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 with text or SVG.
🧹 Script hygiene
Client-side code should be reserved for the parts of the page that truly need it. Audit every script tag.
📐 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. One strong CTA beats three weak ones.
