FAQPage Schema
How do I improve Core Web Vitals like LCP, INP, and CLS on my website?

You improve Core Web Vitals by auditing render-blocking assets, optimizing image delivery, and minimizing JavaScript execution. This provides specific, measurable recommendations for LCP, INP, CLS, and TTFB to speed up your site.

What is the best way to audit and fix render-blocking JavaScript and images for page speed?

The best way to audit page speed issues is to use Lighthouse-driven audits to identify render-blocking assets, excessive JavaScript, and inefficient images. You then prioritize fixes based on their impact on user experience and loading scores.

Can I use Lighthouse audits to tune a mobile ecommerce homepage for better performance?

Yes, you can use Lighthouse audits to tune a mobile ecommerce homepage by identifying performance drains like render-blocking assets and inefficient images. It prioritizes high-impact fixes to reduce dashboard lag and improve mobile page speed.

Why does my web application have slow TTFB and how do I optimize caching to fix it?

Slow TTFB often results from inefficient server responses and lack of proper caching. You optimize caching and asset delivery to reduce Time to First Byte, applying measurable recommendations and validating before-and-after performance improvements.

Does font and image optimization actually help with FCP and Core Web Vitals improvements?

Yes, font and image optimization directly helps with First Contentful Paint and Core Web Vitals improvements. By optimizing asset delivery and controlling resource budgets, you reduce layout shifts and speed up loading across front-end stacks.
