Just tested a bunch and it seems like `path of exile [skill/currency]` usually ranks the Fandom higher while `poe [skill/currency]` ranks the new wiki higher which is why I never noticed (I actually never noticed because I block the PoE Fandom and pin the new wiki on Kagi)
There is an extension which automatically redirects you from Fandom to the new wiki. While that's convenient it probably helps Fandom stay near the top.
It does, if you’re clicking on those fandom links and not subsequently providing any negative signals back to Google it’ll assume that’s where you wanted to go.
It was and remains a worthwhile trade-off to ensure folks got to the right wiki though.
