Hi Adero! This is Chen from Fandom and I'm the community manager to support all wikis under TV/Movie vertical. How are you??
Apologies I can only communicate in English... I'm contacting you because in the next few weeks, we will do some SEO test on some wikis including Pokemon wiki in all languages. The test is that anonymous/non logged-in users will not see the file pages; instead, these file pages will be redirected to the article pages where the file was used/input the first time when anonymous/non logged-in users click the link. For example, if they click "http://xxxxx.fandom.com/File:xxx" on Google and it will link them to an article page.
This won't affect any logged in users at all and you will still be able to click on the file pages. We hope doing so can help your community eliminate low quality, low value pages and make Google like your wiki more by improving the SEO.
I hope to give you a headsup and let you know first. As long as users are logged-in, they won't see any difference. Do you have any questions? Or do you think it's necessary to post a notice about this on Discussions? Feel free to do whichever way you think is the best for your community. Let me know if you have any questions!
