What is Page Speed?
Page speed refers to how quickly a webpage loads and becomes interactive for users. It is measured through metrics like Largest Contentful Paint (LCP), First Input Delay (FID), Cumulative Layout Shift (CLS), and Interaction to Next Paint (INP), collectively known as Core Web Vitals. Google uses page speed as a ranking factor.
Why it matters
Slow pages lead to higher bounce rates, lower engagement, and reduced search rankings, making page speed optimization a prerequisite for both SEO and conversion rate improvement.
