Key takeaways
- Oversized images are the most common cause.
- Heavy plugins, scripts and weak hosting also slow sites down.
- Test on a phone, because that is how most visitors browse.
Test first
Run your page through a speed testing tool and open it on your phone using mobile data. Note which pages are slowest.
Oversized images
Photos straight from a camera or phone are huge. Resize and compress them before uploading, and use modern formats where possible.
Too many plugins and scripts
Each plugin, chat widget and tracking script adds work for the browser. Remove those you do not use.
Weak hosting
Cheap or overloaded hosting can make even a light site slow. If speed is poor after other fixes, look at the hosting.
No caching
Caching saves ready-made copies of pages so they load faster. Many sites can benefit from it.
Heavy design and fonts
Large sliders, autoplay videos and many fonts slow pages. Simple designs load faster and often convert better.
When to get help
If you cannot find the cause, or the site is broken as well as slow, a developer can audit it and fix the problems.

Does a slow site hurt SEO?
Yes. Speed affects visitor behaviour and search performance.
