Compare your theme's data here to your storefront's performance. If your performance is worse, you may have apps and/or customizations impacting it.
If you're shopping for a new theme, you can use this data along with the features of each theme to make a better decision about the tradeoffs.
Use ThemeVitals to identify performance bottlenecks in real-world usage. Compare mobile and desktop Core Web Vitals. Which metric does your theme struggle with the most?
Debug performance further using tools like browser dev tools and WebPageTest on live websites. Then, validate whether theme changes are improving user experience over time.
Web performance is important because it impacts user experience. When websites are slow to load, don't respond promptly to user input, or items on the page move about unexpectedly, users get frustrated and leave.
Great web performance leads to higher conversions. It can also improve your SEO rankings.
