As I said in a comment, Merriam-Webster suggests that analytics is the method of analysis. That's why I would suggest that analytics is Google's term for their analysis tools, or Analysewerkzeuge. Of course the usual focus is on users because websites are used to interact with them. But I would be surprised if analytics didn't also provide ways to measure the technical aspects of a website, like retrieval times, time to page complete, server load etc. But it was hard to find out what analytics specifically offers. See my rant below which is quite on topic here because it is about web user experience, and language in the context of advertising marketing.
<rant> I just spent 10 minutes of my life trying to find out what specific functionality
analytics provides. I started by googling "google analytics". The featured first hit first asks me to sign into google (!? why?) and then gets me to a page with minimal text and three icons.
The first icon asks me to sign up for analytics. (Sorry, what?? Ah, that's why the wanted me to log in!) That's after just three words of explanation, "Analyze your site's traffic", in a headline. OK, so I click "Analytics home" at the bottom. There's a page consisting of — headlines above paragraphs of literally a single sentence each. Money quote: "Build a complete picture". You wish! Big emphasis is on the integration with the other google services and tools. Ah, on the bottom of this page full of fluff is a section "Resources" with a link to "product overview analytics". The click on "Read more" leads to another picture-heavy page with not much text, and all of it fluff. Money quote:
"With Google Analytics, you can uncover the insights that drive real results." No shit, Sherlock! I feel like conversing with a Flat Earther for an hour or two: It's exhausting because you try to take them seriously but that brings you down to their level; it drains your intellectual capacity. I stop my research here, not least because I fear for my sanity.
It's all advertising, no hard facts whatsoever.
Actually, I'm being unfair to that conversation partner, provided they act in good faith: Because google has an obvious agenda. They want to get a foot in the door of your website; they want your data. They aren't even hiding it. They aren't even telling you what they'll do on your site. I almost feel I should give up from exhaustion and just sign up so that they finally tell me.
