I have frequently said to myself, "you know what Fandom needs? More ads"
If I'm looking for a specific piece of info that ends up being on a fandom wiki, it's quite a turn off.
It gets a lot better with an ad blocker and other annoyance-blockers. The deeper question is whether or not you think it’s worth it. I think many people visit Fandom pages only briefly from a SERP and then take off, like Wikipedia but specific to a game. If that’s the way you use Fandom then it’s probably not worth it.
What makes it worth it is if there’s a page specific to a game you like and you spend a good amount of time there reading stuff. That’s a long tail thing though.
Most of the time I don't notice it because I use Firefox w/ uB0 on all platforms. But recently I've been playing some games on Steam and trying to use Steam's browser overlay to cache some guides. Its browser seems to be a chrome fork and does not support any kind of adblocker, unfortunately, and so I've been exposed to just how bad Fandom wikis are without one.
Also, the site is really slow. The only thing that the site manages to turn on is the computer fans.
That's just par for the course for any online service these days, though. It's not like Netflix, Hulu Spotify are keeping their prices flat.
Whenever my phone accidentally opens fandom with Chrome rather than Firefox mobile (with uBO), I wonder how the hell anybody browses the internet on their phone without an ad blocker...
