Website speed affects SEO in two ways. Search systems use load and interaction metrics as quality signals. People leave a page that sits there. You feel the second one in form submits even when you never open Search Console.
The metric names: Core Web Vitals. How to cut weight on WordPress: speed up WordPress. On Shopify: speed up a Shopify store.
A usable mobile load helps you stay in the running. It will not outrank a stronger page. Measure LCP first, usually a hero image, then scripts, then the host.
What Google has said, without folklore
Google has published page experience and Core Web Vitals as ranking-relevant. The exact weight changes and they do not publish a formula you can game. Treat speed as hygiene: get out of the “poor” bucket on the URLs that earn money.

| If this is slow | SEO-shaped risk |
|---|---|
| Homepage hero | Weak LCP, people bounce, fewer useful signals |
| Theme or plugin JS | Poor INP, rage taps, abandoned forms |
| Images without size | CLS, accidental clicks, messy experience |
| Tiny host, no cache | Slow TTFB on every URL |
What speed will not do
It will not make a vague homepage rank for a competitive service. Do the new-site SEO list as well. Images: optimize images. Measure: page speed test.
Hosting if the server is the bottleneck: choose hosting and Hostinger partner page.
