Hashtags on Facebook function as index markers. They categorize content and facilitate its discovery by users interested in specific topics. For example, a user posting about a local music event might use tags that connect their post to the broader conversation about music, local events, or the venue itself.
Effective use of categorized terms can significantly broaden the reach of content beyond an individual’s immediate network. By aligning posts with trending or relevant subjects, content creators increase the likelihood of their posts being seen by individuals actively searching for information on those subjects. Historically, this practice evolved from social media platforms and has become an integral part of content strategy.
