I agree that website speed is a critical factor. Even a few extra seconds of loading time can make visitors impatient and increase the chances of them leaving before completing a purchase.
Speed also affects the overall user experience and can influence search engine performance. A fast, responsive website builds trust and makes it easier for customers to browse, compare products, and checkout.
So while the exact “four-second” statistic may vary depending on the study and situation, the main point is definitely valid: website speed matters, both for customers and for SEO. Investing in performance optimization can ultimately mean better engagement, rankings, and conversions.
