Labels
Tag posts by campaign or content pillar and filter by them later. Labels are never posted.
Adding labels
Pick or type labels on a post in the composer. They stay inside this workspace and are never sent to a network. Use them to filter Publish and Analytics by campaign, and the analytics CSV follows the same filter.
Changing a post's labels does not clear its approval, because nothing that goes out changes.
Renaming, merging and removing
Labels in this workspace, on Publish, lists every label. Rename one, merge two spellings of the same campaign into one, or remove a label. Every post carrying it changes at once.
