Achieving Perfect Lighthouse Scores in 2025

In 2025, achieving perfect Lighthouse scores is no longer just a nice-to-have—it's essential for competitive advantage. With Google's continued emphasis on Core Web Vitals and user experience signals, websites that score 95+ across all Lighthouse metrics see dramatically better search rankings, conversion rates, and user engagement.

• 40% higher search rankings for competitive keywords
