Question 1

What do you measure in a performance audit?

Accepted Answer

I audit Core Web Vitals (LCP, INP, CLS), Lighthouse scores, bundle size, render-blocking resources, image optimization, server response times, caching headers, and JavaScript execution time. I use Lighthouse, WebPageTest, and Chrome DevTools for comprehensive analysis.

Question 2

How much can performance be realistically improved?

Accepted Answer

Most websites I audit see a 30-70% improvement in Lighthouse scores and significant Core Web Vitals gains. Results vary by starting point - sites with unoptimized images, large JS bundles, and no caching tend to see the biggest improvements.

Question 3

What is included in the performance audit report?

Accepted Answer

You receive a detailed PDF report with current metrics, identified bottlenecks ranked by impact, actionable recommendations with code examples, and an implementation priority matrix. I also include a before/after comparison of key metrics.

Question 4

How long does the audit take?

Accepted Answer

A standard performance audit takes 3-5 business days. I analyze all key pages (homepage, product pages, checkout), run tests on multiple devices and network conditions, and prepare the full report with recommendations.

Question 5

Do you also implement the fixes after the audit?

Accepted Answer

Yes. I offer a combined audit + implementation package where I identify the issues and fix them. This is the most efficient approach as I already understand your codebase from the audit phase. Implementation time varies from 1-4 weeks depending on the scope of improvements.
