Why your website is slow on phones (and 5 fixes that work)

Most of your visitors are on a phone, often on mobile data. These are the usual reasons a site feels slow, and what to fix first.

A slow website loses visitors before they read a word, and Google uses page experience as one of many ranking signals. The good news: the causes are usually the same few things.

First, measure it

Open Google PageSpeed Insights, enter your address and look at the mobile result. Pay attention to Largest Contentful Paint: Google considers 2.5 seconds or less good.

1. Compress your images

Huge photos straight from a camera or phone are the most common problem. Resize them to the size they are shown at and use modern formats like WebP.

2. Remove what you do not use

Old plugins, sliders, chat widgets and tracking scripts all add weight. Keep only what earns its place.

3. Use caching and a CDN

Caching stops the server from building every page from scratch; a CDN serves files from a location close to the visitor.

4. Load fonts carefully

Two font families with a few weights are plenty. Every extra weight is another file to download.

5. Check your hosting

Very cheap shared hosting can make every page slow, however well it is built.
