Thanks. Almost all of that makes good sense, and it's pretty clear that optimization kept working so they just kept doing it. I wonder how much farther it will go.
You lost me here though:
> Hundreds of pages a day that were of absolutely no use to anyone but to Google
Do you mean like spam/clickbait blog posts on their own domain? I'm having trouble connecting "producing garbage content" to "increased ranking from google".
Think along the lines of those recipe pages that have 2000 words of backstory that no one cares about but is considered good SEO practice in Googles eyes.
