Why is website performance crucial for SEO and user experience?
Performance is a dual lever: it boosts both user satisfaction and SEO rankings, making it a critical investment.
Website performance directly impacts user satisfaction, conversion rates, and search rankings. Search engines like Google use Core Web Vitals as ranking signals, and users expect fast-loading pages.
- User experience: Slow sites frustrate users, increasing bounce rates.
- SEO rankings: Faster sites are rewarded with higher positions.
- Conversion rates: Even a 1-second delay reduces conversions by 7%.
What are the key metrics to analyze in a performance audit?
Focus on Core Web Vitals as they are measurable, user-centric, and directly influence SEO.
A thorough audit focuses on Core Web Vitals and other critical metrics:
- Largest Contentful Paint (LCP): Load time of main content (should be under 2.5s).
- First Input Delay (FID) or Interaction to Next Paint (INP): Responsiveness (under 200ms).
- Cumulative Layout Shift (CLS): Visual stability (under 0.1).
- Time to First Byte (TTFB): Server response time (under 600ms).
- Total Blocking Time (TBT): Long tasks delaying interactivity.

Yes, Google uses page experience signals including Core Web Vitals as ranking factors. Improving performance can boost your visibility in search results.
