How to Improve Website Speed: 10 Practical Fixes

Who this is for: Website owners whose site is slow and who want to fix it.

Measure first

Use PageSpeed Insights and your Search Console Core Web Vitals report to see which pages and metrics need attention.

The 10 fixes

1. Compress and resize images; use WebP or AVIF.
2. Lazy-load images below the fold.
3. Set width and height on images to prevent layout shift.
4. Remove unused plugins and scripts.
5. Defer non-critical JavaScript.
6. Limit web fonts and use font-display: swap.
7. Enable caching and compression on the server.
8. Use a CDN for static assets where useful.
9. Upgrade underpowered hosting.
10. Avoid heavy background videos and sliders above the fold.

Prioritise

Fix the largest elements on your most visited pages first — often the hero image. Then address scripts and hosting.

Keep it fast

Speed degrades as content and plugins are added. Regular checks as part of Cloud Hosting, Deployment and Maintenance keep it under control. Also read our Technical SEO Checklist for Business Websites.
