Page speed basics that matter

• Optimise images: resize them to the size they are shown and use modern formats like WebP.
• Load less JavaScript: every script has to download and run before pages feel ready.
• Cache: let browsers cache static files and let the server cache expensive work.
• Use a CDN for visitors far from your server.
• Choose decent hosting: a slow server makes everything else irrelevant.

Measure before and after with your browser's developer tools; guessing wastes time.
