Results will be based on the actual test report. Scores are not generated until the testing functionality is available.
Core Web Vitals help you understand how quickly your content appears, how responsive your website feels, and how stable the page remains while loading.
Measures how long it takes for the largest visible image or text block to render on the screen.
Measures the total time the browser's main thread is blocked by long tasks during page loading, preventing it from responding promptly to user input.
Measures unexpected movement of page elements while the content loads or updates.
These results represent Lighthouse lab measurements. INP may be unavailable in a lab test because it measures real user interactions. Field data is needed to assess actual user-experienced INP.
Website speed depends on several technical factors. Understand the common areas to review when improving loading performance, responsiveness, and user experience.
Not every optimisation has the same impact. Start by reviewing actual test findings, identify the main performance bottlenecks, and prioritise fixes according to their likely impact.
Compress oversized images, use modern formats where appropriate, and serve responsive image sizes to reduce unnecessary downloads.
Review unnecessary JavaScript and CSS, remove unused assets where safe, and reduce render-blocking resources.
Review hosting performance, caching, time to first byte, and database or server-side processing overhead.
Set image dimensions, reserve space for advertisements or embeds, and avoid inserting unexpected content above existing elements.
Test on mobile devices, reduce unnecessary network requests, and make sure interactive elements respond without excessive delay.
These are general optimisation recommendations. The right fixes for your website should be determined by its actual test results, page structure, and technical setup.

A page speed check evaluates how a web page loads, responds to interactions, and behaves during loading. Performance testing can help identify technical issues that may affect user experience and loading efficiency.
Core Web Vitals are Google's user experience metrics: Largest Contentful Paint (LCP) measures loading performance, Interaction to Next Paint (INP) measures responsiveness, and Cumulative Layout Shift (CLS) measures visual stability.
For Google PageSpeed Insights lab performance scores, 90–100 is considered good, 50–89 needs improvement, and below 50 is considered poor. However, a single score does not tell the whole story; Core Web Vitals and real-user experience also matter.
Common causes include large images, excessive JavaScript, render-blocking resources, slow server responses, and too many network requests. The actual cause depends on your website and should be identified through performance testing.
Page experience and Core Web Vitals are part of Google's search considerations, but good scores do not guarantee higher rankings. Relevant content, relevance, and other ranking systems remain important.
Test your website after significant design, plugin, theme, or code changes. Regular checks are also useful when adding new features, installing third-party scripts, or investigating performance problems.
The page design is being prepared for actual performance testing. Real scores and diagnostic results will only be displayed after the testing service and API integration are implemented.
