What Is a Hashtag?

A hashtag is a word or phrase preceded by the "#" symbol used to group and categorise content on social media platforms.

A hashtag is a simple but powerful tool used on platforms like Instagram, TikTok, and X (formerly Twitter) to make content discoverable. When users include a hashtag in their post, it becomes part of a larger conversation — anyone searching or clicking that hashtag can see related content.

Hashtags help people find topics they're interested in, and they allow brands to reach wider audiences. For example, using a branded hashtag like #GleamGiveaway can help you track campaign participation or build awareness. Hashtags can also connect user-generated content, promote trends, or support community building.

Using relevant hashtags strategically increases visibility, engagement, and searchability — especially when paired with a clear content plan or social contest.
