How does website speed and performance affect SEO and user experience in Google search, and what role does Jamstack play in optimizing these factors?

I think that's important for a few reasons. 

First is a business reason. If your website is slow, you are simply losing your customers, because people don't want to wait for page. If something is slow, they will just leave your website. So that's an opportunity to provide a really smooth user experience and create a product that people really like, recommend to friends, and return to. Performance is just one part of UX. Core Web Vitals actually focus on general user experience. It's about how smooth your website is, if it's not clunky, if the content stays and doesn’t jump for whatever reason.

I think the second reason is because of the cost. If your website is fast, you don't have such a high cost for the server, because if everything is faster, then you need less power to execute all of this. It’s obvious, but if you do less, then you pay less. That's a win. Another reason why we like fast websites and fast apps is the environmental side. If you have a faster website, it will produce less carbon footprint. 

Those three reasons are the most important for us. The user experience is definitely number one. If you can improve this, basically everything else will be better as well. Like A/B testing -- if it's faster, then it can be more accurate, because you are eliminating the factor of speed.
