Reach & Discovery
Hashtag
A keyword or phrase prefixed with # that categorises content and helps people discover it.
A hashtag is a word or phrase preceded by # that labels your content by topic, helping platforms categorise it and helping users discover it through search and topic feeds.
In 2026, hashtags work best as topic signals rather than reach hacks. A focused set of 3–8 relevant tags — mixing broad, mid-size and niche — outperforms stuffing 30. Caption keywords now matter alongside hashtags, since platforms increasingly index the words in your post.
Avoid banned, spammy or wildly irrelevant tags, which can suppress reach.
