Why does site speed matter?

Why does site speed matter?

Website speed — also known as website performance — refers to how quickly a browser is able to load fully functional web pages from a given site. Poorly performing sites that render slowly in a browser can drive users away. Conversely, sites that load quickly will typically receive more traffic and have better conversion rates.

Speed impacts user experience

Users expect pages to load in under 3 seconds. Studies show that 53% of mobile users abandon sites that take longer than 3 seconds to load, and each additional second of load time increases bounce rates by up to 32%.

Speed impacts revenue

For e-commerce sites, a 1-second delay in page load time can result in a 7% reduction in conversions. Amazon found that every 100ms of latency cost them 1% in sales.

Speed impacts SEO

Google uses page speed as a ranking factor for both desktop and mobile search results. Core Web Vitals — a set of metrics measuring loading performance, interactivity, and visual stability — directly influence search rankings.
