Frequently Asked Questions
Everything you need to know about website performance
What are Core Web Vitals and why are they important?
Core Web Vitals are a set of specific metrics that Google considers important for measuring the user experience of a web page. They include First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS). These metrics directly impact your search rankings.
What's the difference between mobile and desktop testing?
Mobile devices typically have slower connections, smaller screens, and less processing power. Our tool simulates both environments to give you accurate performance data for each device type. Mobile performance is often more critical as it affects the majority of users.
How can I improve my website's loading speed?
Common optimization techniques include: compressing images, minifying CSS/JavaScript, using browser caching, reducing server response times, and eliminating render-blocking resources. Our tool provides specific recommendations based on your website's analysis.
What does the performance grade (A-F) mean?
The performance grade is calculated based on your overall score: A (90-100): Excellent, B (80-89): Good, C (70-79): Fair, D (60-69): Poor, F (0-59): Very Poor. This gives you a quick understanding of how your website performs compared to industry standards.
