They've done a lot, but apparently it hasn't been particularly successful. Their new "Documentation" platform didn't really ever gain traction: https://meta.stackoverflow.com/questions/354217/sunsetting-d...

[hehheh]

I don't think I ever saw a Documentation page in a search result. Instead, I saw (and see) dozens of copies of the same SO Q&A content spread across multiple sites. I wonder if they would have had better success if they adjusted their SEO strategies and went after the rehosting sites (more?) aggressively.

Google was never pointed at Documentation, so you wouldn't find it there. There were constant concerns within the meta SO community about the quality of the content and how embarrassing it would be (not a small fraction of it was worse than W3Schools of old - https://meta.stackoverflow.com/questions/334638/ ). It could have been rather damaging to the SO brand to have such poor material shown as examples of what is desired.
