Find common mobile performance problems and prioritise improvements to loading, interaction and layout stability without redesigning everything.
Start with the page customers actually use
Test the landing page linked from your ads or business profile, not only the homepage. Open it on a phone and complete the main task. Note whether important content arrives late, the menu feels slow or the page moves while you try to tap a button.
Keep a screenshot and a short description of each issue. This gives your developer a repeatable problem rather than a vague request to “make it faster”.
Understand three useful measurements
Google’s Core Web Vitals cover loading through Largest Contentful Paint, responsiveness through Interaction to Next Paint and visual stability through Cumulative Layout Shift. The published good thresholds are LCP within 2.5 seconds, INP at most 200 milliseconds and CLS at most 0.1, assessed at the 75th percentile of page loads.
A single lab test is a diagnostic aid, not a complete picture of every visitor’s experience. Review real-user data where it is available.
Prioritise fixes with visible impact
- Resize oversized images and serve suitable formats.
- Reserve space for images and embeds so content does not jump.
- Avoid loading large background videos when a smaller image explains the offer.
- Review unused scripts and third-party widgets.
- Keep the most important initial content easy to load.
- Test forms, menus and buttons after each change.
Balance speed with the customer journey
Removing essential information just to increase a test score can make a page less useful. Keep pricing context, contact options and clear service information. Prioritise work that improves the visitor’s ability to understand and act.
After a release, compare the same pages and devices, check real-user trends when enough data exists and inspect enquiries for errors. Record what changed so future developers do not reintroduce the same issue. A fast page with a broken form still cannot serve customers.
Frequently asked questions
Does a perfect speed score guarantee sales?
No. Performance supports usability, but the offer, content and checkout or enquiry experience also matter.
Should every image load immediately?
No. Prioritise important visible content and load lower-page media appropriately. Avoid delaying the main image customers see first.
