Click "Site tools" and then "Orphaned pages."
There are quite a few orphaned pages, each on a different optimization subject, but as I looked through, I compared it to the optimizations page.
As far as I know, all of those each also have a section in the optimization page. We have a page for each section, but then we have it all compiled into one page. IDK, but isn't that a little odd? Not to mention they're orphaned, so…
I wanted to know if there was a reason for doing this that I don't know about, before I did anything.
