Common Questions
FAQ
What's included in a performance audit?
Full Lighthouse and PageSpeed Insights analysis, waterfall profiling, bundle size breakdown, LCP/CLS/INP root cause identification, and a detailed findings report. Implementation of fixes is included — not just recommendations.
How long does a performance optimization take?
Audit + report: 1–2 days. Fix implementation: 3–5 days depending on scope. Total: typically under 1 week from start to re-test.
Can you guarantee a score improvement?
I guarantee measurable improvement on every project. The degree depends on the current state of the site — sites starting below 50 typically see the largest gains (often 2×). I share the before/after numbers transparently.
What tech stacks do you work with?
React, Angular, Astro, Next.js, Vue, and vanilla JS. Any framework that compiles to HTML/CSS/JS. I've optimized both client-rendered SPAs and server-rendered apps.
How much does a performance audit cost?
Performance audits start at ₹10,000 ($120) for a focused Core Web Vitals audit. Full optimization with implementation starts at ₹25,000. Pricing depends on the size and complexity of the site.
