Frequently Asked Questions
How accurate are the performance scores?
Our tool provides estimates based on common performance patterns. For precise measurements, use Google PageSpeed Insights or test with real devices and network conditions.
Why do scores vary between tests?
Performance can vary due to server load, network conditions, browser state, and third-party resources. Run multiple tests and focus on consistent issues rather than single scores.
Should I prioritize mobile or desktop performance?
Prioritize mobile performance since Google uses mobile-first indexing. However, ensure both mobile and desktop provide good user experiences for your audience.
How do I fix Cumulative Layout Shift issues?
Set width and height attributes on images and videos, reserve space for ads and embeds, avoid inserting content above existing content, and use CSS aspect-ratio for responsive media.
