Isn’t the whole point of these metrics in SEO to give a sort of tie-breaker on searches with a lot of very similar results? Aren’t you just competing with other companies, not the metric itself?
Like, I’m pretty sure if you have a really slow page about pink moon dragons, so long as it’s not completely broken, and gets indexed, it will be the top result when you search on “pink moon dragons”.
Now, if someone else comes around, and also makes a site about pink moon dragons, you just gotta beat those assholes. If they have a 6/100, and you got a sweet 12/100, you’re still #1.
That page is a press article on a promotional corporate blog where google is releasing information about the sustainability of their server farms. It’s probably just got a lot of weird scripts, and it has an embedded video, etc. It loads fine, it’s just not theoretically streamlined. They probably aren’t shooting for PageSpeed whatevers. They aren’t peddling umbrellas.
Speaking of umbrellas, all the different projects and departments at a big corporation are separate business entities, almost like separate companies under one umbrella corp. The right hand doesn’t know what the left is doing. They don’t care, either.
