How to Improve Website Speed: A Practical Checklist

Website speed is one of the few technical factors that directly affects both user experience and search visibility, which makes it worth taking seriously even if you're not technical yourself.

Where speed problems usually come from

• Unoptimised images — the single most common cause of slow websites
• Too many third-party scripts — trackers, chat widgets and embeds that each add load time
• Unnecessary animation libraries — heavy JavaScript for effects that add little value
• Poor hosting or server response time — the foundation everything else sits on

A practical checklist

1. Compress and correctly size every image before upload
2. Use modern image formats (WebP or AVIF) where supported
3. Audit third-party scripts and remove anything not actively used
4. Load non-critical scripts after the main content, not before it
5. Choose fonts carefully and avoid loading unused font weights
6. Test on a real mobile connection, not just a fast office Wi-Fi

Why it matters for search rankings

Search engines use page experience signals, including loading speed, as part of ranking. A faster site doesn't guarantee a higher ranking on its own, but a slow site can hold an otherwise strong page back.
