Improve SEO Page Speed with WebP Assets
Google uses page loading speed as a primary ranking signal in search results. Heavy PNG and JPEG assets slow down page loads, increasing bounce rates and hurting rankings. Converting your images to WebP helps you achieve high optimization scores on Google PageSpeed Insights.
