In more detail
Tagging covers two related moves: mentioning an account by its handle (like @brand) in a caption or comment, and tagging accounts or a location directly in a photo or video. Both create a clickable link back to that account and usually send it a notification. As a strategy, tagging gets your post in front of audiences you do not own yet. Tag a partner, a customer who features your product, or a creator you collaborated with, and your content can show up in their tagged feed or get reshared to their followers. It is different from hashtagging, which groups content by topic rather than by account. Used well, tagging builds relationships and reach. Used carelessly, tagging unrelated accounts to chase attention reads as spam and can hurt you.
Example
A coffee brand reposts a customer photo and tags the customer's account plus the cafe location. The customer gets notified, often reshares it to their own followers, and anyone browsing that location now sees the brand's post too. One tag turned a single photo into reach across three audiences.
