People leave a page that takes too long. On mobile data, every extra megabyte counts.
The usual causes
- Huge images. A photo straight from a phone can be several megabytes.
- Too many plugins and scripts that each add loading time.
- Weak hosting that responds slowly.
- No caching, so the page is rebuilt for every visit.
- Autoplaying videos and heavy sliders.
How to test
Run your address through Google's PageSpeed Insights. It shows how fast your site is on mobile and what to fix.
Fixes that matter most
- Compress and resize images, and use modern formats such as WebP.
- Load images lazily, so ones below the screen load later.
- Remove plugins and scripts you do not use.
- Use caching and a content delivery network.
- Choose reliable hosting close to your visitors.
The three speed measures
Google looks at how quickly the main content appears (LCP), how fast the page responds to taps (INP), and how stable the layout is while loading (CLS). Good sites aim for a main content time of about 2.5 seconds or less.
Test on a real phone
Do not only test on fast office wifi. Try it on mobile data.
We build lean sites, and can also fix an existing one with Website Redesign or Maintenance.
