Google is no longer trying to index the entire web. In fact, it's become extremely selective, refusing to index most content. This isn't about content creators failing to meet some arbitrary standard of quality. Rather, it's a fundamental change in how Google approaches its role as a search engine.

[...]

Now, for each piece of content, Google decides if it's worth indexing, and more often than not, the answer seems to be "no." They might index content they perceive as truly unique or on topics that aren't covered at all. But if you write about a topic that Google considers even remotely addressed elsewhere, they likely won't index it. This can happen even if you're a well-respected writer with a substantial readership.

Interestingly, I've noticed that when content does manage to get indexed, it often ranks surprisingly well. It's as if the hurdle of getting indexed has become so high that once you clear it, you're already most of the way to ranking. However, getting to that point has become exponentially more difficult.

Importantly, this extreme selectivity isn't applied equally. Big, recognized brands often see most of their content indexed quickly, while small bloggers or niche websites face a much higher bar for inclusion.

si fecero custodi delle termopili, 
sono degni di più grande onore 
se prevedono (e molti lo prevedono)
che all’ultimo comparirà un efialte 
e comunque i persiani passeranno
