Why your website is slow on mobile data — and how to fix it

Your site may feel fast on office Wi-Fi and crawl on a phone. The usual culprits, and the fixes that make the biggest difference.

Websites

Most of your visitors arrive on a phone, often on mobile data, often on a mid-range device. Testing on a laptop on fast Wi-Fi hides the problems they feel.

01Images are usually the biggest cost

Uncompressed photos and banners in the wrong size are the most common reason a page is heavy. Modern formats, correct sizing and lazy-loading below the fold fix most of it.

02Too many scripts

Chat widgets, trackers, sliders and pop-ups each add weight. Keep the ones that earn their place and load the rest later.

03Fonts and layout shifts

Text that jumps as fonts load, or buttons that move as images appear, make a site feel slow even when it isn't. Reserving space for each element solves it.

Speed isn't a technical detail. It's the first thing your site says about you.

Every website we build is tested on real phones before launch and handed over with the source code, so the next developer doesn't start from zero.
