Measure one useful journey first

Choose a page that matters: a landing page, service page or enquiry form. Record how it behaves on a realistic mobile connection. A fast homepage does not prove the booking journey is fast. Use the same page and test conditions when comparing changes so the result reflects the work rather than a different connection.

Inspect the largest visible assets

A large hero image is a common place to investigate. Check its downloaded size against the size at which it appears. Supply appropriately sized images and reserve their layout space. Avoid delaying the main visible image unnecessarily, while deferring images far below the initial view can reduce competing work.

Question every script

List analytics, chat widgets, animation libraries and third-party embeds. For each, ask who uses it and what would happen if it loaded later. A tool that adds little business value should not block the enquiry form. Remove abandoned integrations rather than adding another performance plugin to compensate for them.

Protect interaction and stability

Try clicking navigation and typing while the page loads. Watch for buttons moving as images appear. A page that looks ready but ignores input is frustrating. MDN treats performance as part of the user experience; in your own testing, record both loading behaviour and the time until the key task feels responsive.

Verify the improvement

Change one major factor at a time, then repeat the same test. Check image quality and functionality after compression or script removal. Keep a small performance budget for future additions: every large asset or widget should have a clear purpose. This prevents the next marketing update from undoing the gains.
