In Google's search algorithms, user experience and load performance are official ranking factors. A slow website loses both search rank and client conversions.
Understanding Core Web Vitals Metrics
- Largest Contentful Paint (LCP): Measures how fast the main hero content loads. Target: under 2.5 seconds.
- Interaction to Next Paint (INP): Measures page responsiveness when a user clicks a button. Target: under 200 milliseconds.
- Cumulative Layout Shift (CLS): Measures visual stability while loading. Target: score below 0.1.
Performance Fact: Achieving a 95+ score on Google PageSpeed Insights reduces visitor bounce rate by up to 50%.
Proven Techniques for 95+ Lighthouse Scores
