Performance work is easiest when it is part of the build, not a rushed fix after launch. Product and marketing teams should know which decisions affect speed before they approve a page.

Images should have clear dimensions, sensible formats, responsive sizing, and descriptive alt text when the image carries meaning. Decorative visuals should not become the largest resource on the page.

Fonts and JavaScript deserve the same attention. Load only the weights you use, avoid unnecessary outside scripts, and keep interaction code focused on what the page actually needs.

Finally, check the experience on mobile. A page that feels smooth on a desktop monitor can still shift, block input, or bury the main call to action on a phone.

Performance starts with design and content choices

Performance is not only an engineering task. Large images, heavy animation, unnecessary scripts, too many font weights and unclear content hierarchy can all slow the experience.

Teams should review speed while pages are being designed, not only after launch. This keeps the page useful on mobile connections and reduces avoidable rebuild work.

Check the page like a visitor would use it

A fast score is useful, but the visitor experience matters too. Check whether the main content appears quickly, whether forms are easy to use, whether buttons are stable and whether text remains readable on smaller screens.

Performance work should protect the business goal. A service page that loads quickly but hides the enquiry path still needs improvement.

Practical takeaways

  • Set image sizes and avoid oversized visual assets.
  • Limit font weights and unnecessary outside scripts.
  • Watch for layout shifts caused by content that loads late.
  • Test mobile performance as a core experience.

Oversized images, unused scripts, heavy animation, third party tools and layout shifts are common causes.

Should mobile performance be tested separately?
