Page Speed
Page speed refers to how quickly a web page loads and becomes fully interactive for users. It's measured in various ways, including time to first byte (TTFB), first contentful paint (FCP), and largest contentful paint (LCP). Page speed is a confirmed Google ranking factor and significantly impacts user experience, bounce rates, and conversion rates. Faster-loading pages provide better user experiences and are favored by search engines, making speed optimization crucial for SEO success.
