Q: How much does performance optimization cost?

From €3,900 — typically 1-2 sprints to bring Core Web Vitals from red/yellow to green on critical pages. Comprehensive site-wide optimization on request (image optimization, code splitting, lazy loading, CDN setup, font optimization).

Q: How long does it take to fix Core Web Vitals?

Quick wins (image compression, lazy loading, font preload): 1 week, often moves LCP from red to yellow. Full optimization (code splitting, CDN, font subsetting, JavaScript defer): 2-3 weeks, brings most sites to all-green CWV. Google Search Console reports the improved scores within 28 days of fix.

Question 1

What are Core Web Vitals?

Accepted Answer

Core Web Vitals are Google's three official ranking metrics: LCP (Largest Contentful Paint) measuring loading speed (<2.5s for good), INP (Interaction to Next Paint) measuring responsiveness (<200ms), and CLS (Cumulative Layout Shift) measuring visual stability (<0.1). Sites with all three in the green get ranking boost; sites with failing scores get demoted.
