How do you add a new Tracked Tag on old school Search Pages?
1. Enter the new tag you want to track in the address bar in this format and search for it:
In this case we’ll add tumby: www.tumblr.com/tagged/tumby
2. Notice that the #tumby appears in the top-right.
Track this tag displays underneath the new tag you added. Click that and you’re done.
You just added the new tag to your tracked tag list that appears when you click on the search box. You’ll need to refresh the page at least once to see it.
