Good User Experience is Good Business
Google’s stated purpose is to provide the end-user with the best possible result for a given query.
This goes beyond just finding the most accurate result. It also means giving the result with the best presentation, or in other words, the best user-experience (UX).
Google wants your website to have valuable content, to be secure, to be logically organized, and to load quickly.
Traditional workarounds to this problem like server-side rendering (SSR) come with significant performance trade-offs.
SSR drags down your time-to-interactive: that means your pages will be visible to the user more quickly, but will be unresponsive when they try to click on something, causing them to bounce off the page in frustration.
Server-side-rendering also causes a notable dip in your time-to-first byte (TTFB) latency. TTFB is a factor of your first contentful paint (FCP). FCP is one of the Core Web Vitals metrics measured in the Google Lighthouse Report. That’s bad news if you’re optimizing for Google’s Page Experience update.
Prerender® Pages Are Blazing Fast
Prerender® pages are rendered in advance on fast servers with a server-response time of under 500 ms. That means your pages load quickly on command and are optimized for the user-agent, whether human or search engine bot – providing the best user experience possible.
This makes your human users happy because all of your content loads quickly and becomes interactive almost immediately. This also makes Google happy and you’ll pass your Google Pagespeed Insights tests with flying colors.
Happy users. Happy Google. Happy you.
