Open the new/staging page https://stg.getfedora.org/, Ctrl+F, type "KDE" as search string... Nothing. Type "gnome", nothing. Etc...
This is rather poor keyword/text search optimization.
This use case should Just Work(tm). Not only would it help end users but also search engines.
Are you aware of editions vs. spins? There is no Gnome anymore since F21, the edition which uses Gnome is Workstation. KDE and all other spins are not editions, they have their own websites and live on spins.fp.o or labs.fp.o. This has nothing to do with SEO, sorry.
If you are looking for the more used desktop spins, we have direct links on the main index now.
+1 to robyduck with the wontfix -- this is definietly not a bug -- if you search "fedora gnome" in the most popular web search, the first entry is:
https://getfedora.org/en/workstation/
And if you search "fedora kde": the first entry is:
https://spins.fedoraproject.org/en/kde/
Which are both the best places for these to go, so this is actaully working better than having the keywords on the main get fedora page. if someone wants Fedora with GNOME, they want workstation, not to go to the main getfedora page, and have to click through. Same for the KDE spin.
