Followed searches are a way to follow searches, just like you’d follow blogs. Periodically, some of the best new posts from those searches will appear on your dashboard.
To follow a search on the web:
Just search for something, then click “Follow” on the right side of the resulting tag page. To view your followed searches, click the search box.
To stop following a search, click in the search box, click the search term you’re looking for, and click “Unfollow” on the right side of the tag page.
To follow a search using our mobile apps:
Just search for something, then tap “Follow” in the search box. To view your followed searches, navigate to the search page - they’ll be waiting for you at the top of the page.
To stop following a search, enter the search term in the search box, then tap “unfollow” in the search box. Alternatively, from the tag result page, click the the meatballs menu (●●●) in the upper right corner, then choose “unfollow” from the menu.
Tip: Clicking or tapping the meatballs in the upper right corner of a followed search post in the app will give you some choices: dismiss that particular post, unfollow the search, or report the post as inappropriate.
If you're wondering what happened to tracked tags, any tags you were previously tracking now show up as followed searches. But you can still get to tag pages by visiting the URLs directly (i.e., http://tumblr.com/tagged/pizza).
