Speed Is a Ranking Factor
Google has confirmed that page speed is a ranking factor. Beyond rankings, slow sites frustrate users and hurt conversions. Every second of delay can cost you customers.
Core Web Vitals Explained
Google measures speed through Core Web Vitals:
Largest Contentful Paint (LCP)
How quickly the main content loads. Target: under 2.5 seconds.
First Input Delay (FID) / Interaction to Next Paint (INP)
How quickly the page responds to user interaction. Target: under 100ms.
Cumulative Layout Shift (CLS)
Visual stability—does content jump around? Target: under 0.1.
