What is this check, and why should you care
Having a cache hit ensures the fastest possible delivery of content to end users.
The response header section-io-cache had a value of Hit.
Section has documentation on this default header in the Varnish cache module.

The time that it takes for a user's browser to receive the first byte of page content.
The lower the TTFB, the faster your site will be perceived by the end user.
To get maximum points, your TTFB must be less than or equal to 30ms. If your TTFB is more than 1 second then you get no points here.

Caching HTTP 404s is a great way to offload requests from your origin.
To get maximum points, you need to have the ability to cache an HTTP 404 for any amount of time.

You can increase the cache hit rate of your site by stripping certain query parameters from the cache key.
FBCLID is one such parameter that can be stripped by your caching server. This query parameter only really serves a purpose for Javascript to read, and Javascript can still read it from the browser URL.

What is this check, and why should you care
The purpose of HTTP compression is to reduce the size of the files sent by a CDN/web server by eliminating redundant information in those files. The smaller the size of the files, the more quickly they can be served over the World Wide Web.
On top of faster delivery, compression also reduces the amount of bandwidth used by the CDN/web server. This is especially important for mobile devices, where the bandwidth is often limited.
The response header Content-Encoding had a value of gzip.
See the Wikipedia page on HTTP compression for more background.
To get maximum points, you need to use Brotli or Zstandard compression.

Using a long cache lifetime helps to ensure a high cache hit rate.
To get maximum points, your cache lifetime must be greater than or equal to 4 weeks. If your cache lifetime is less, then you will get some proportion of the score based on how close to 4 weeks you are.
The current cache lifetime is 900 seconds (15 minutes).

What is this check, and why should you care
Using ETag identifiers is an easy way to ensure your visitors are always getting the most up-to-date version of the content. This mechanism allows caches to be more efficient and saves bandwidth, as a Web server does not need to send a full response if the content has not changed. HTTP 304 responses are used to indicate this is working.
No ETag header was found in the response.
See the Wikipedia page on ETag for more background.
To get maximum points, you need to have ETag identifiers and an HTTP 304 response must be received when using a valid If-None-Match request header.
