Regarding SEO, What’s stopping maintainers from vandalizing their own fandom page?
It would not be difficult to make a bot to update fandom page with a convincing but slightly wrong info, after a few hundred iterations, it’s all useless. Go look at what google recommend and do complete opposite. I’m convinced this will bomb ranking and put whatever wiki they migrated to at the top.
Misinformation may reduce repeat visit, that part, I have no idea if google take into account when they rank the result. Domain/page age also plays a role. But what about other “problems”? If I try to de-optimize every items on that guide, will it speed up the de-rank as well?
