Google ranks slow pages lower, shoppers give up, and your ad budget does the work you already paid for — badly. In plain English, here's what makes a site slow, how to check yours in ten minutes, and when it's worth calling in a rescue.

What's a good website speed score?
Google's Core Web Vitals give green ranges for its three real-phone measurements: LCP under 2.5 seconds (how fast the main content appears), CLS under 0.1 (how stable the page is), and INP under 200ms (how responsive clicks feel).
