TTFB	When did the content start downloading? This is the time spent by Kirby to render the HTML. While it might depend on the quality of your hosting, you can usually improve it by applying various caching techniques. Targeting a value ≤800ms should be our goal.
Speed Index	How soon did the page look usable? Optimising all assets' size, loading order and priority is critical to drawing content quickly, and the waterfall view is the starting point for this.
LCP	When did the largest visible content finish loading? Scoring well on the LCP requires performantly serving high-quality images at the first fold on all targeted devices.

Blocking	Was the main thread blocked? You need to minimise the effect or remove resources that are blocking the website from being ready for user input. Too many fonts or fonts without swapping, as well as external JS/CSS files, need to be linked with performance in mind.
Performance	What is the overall performance like? This Lighthouse core web vitals score considers many factors and provides a good overview and valuable hints about how to solve issues.
SEO	What do Search Engines see? Your website might have the technical implementation correct, but the structure of the HTML document and content must also be considered.
