In my original article I warned that a slow website could hurt visitors and discoverability. I focused on the hosting company: choose fast servers and move if performance disappoints. That can be right, but the host is only one part of loading speed.
Measure before moving
Large images, numerous scripts, fonts or browser-side code can also delay a page. Test a few important pages on mobile and see where the time goes. Compare several visits and check whether slowness affects the whole site or a single page. A new server will not help much if the largest delay lives in the page itself.
Google says Core Web Vitals are among the experience signals its systems use, but a good score does not guarantee a high ranking. This corrects the overly absolute SEO claim in my old article. Speed matters especially because people can read, search and order without long waits.
Questions for a host
If the server is the bottleneck, ask how performance is monitored, what happens under heavy traffic and how easy it is to move. Keep a copy and measure again after a change. Use PageSpeed Insights as a starting point, but do not trust one test score alone. The goal is a page that real visitors can use quickly.
