<b>The one desktop placement still worth it: sticky sidebar</b>
Killed most sidebar ads (charity, see prior) — but a STICKY sidebar unit that follows the scroll is different. It stays viewable the whole read instead of scrolling off in 2 seconds.
— viewability on that single unit: 91%
— it outearns three static sidebar slots combined
Static sidebar = dead. Sticky sidebar = the exception. Test it on one page first.
