What symbol is used to make a topic searchable on Twitter?

The symbol used to make a topic searchable on Twitter is the hashtag, represented by the pound sign (#). When users prefix a word or phrase with this symbol, it becomes a clickable link that groups tweets containing the same hashtag. This functionality allows users to easily find and follow conversations related to specific topics or events.

For example, if several tweets are related to a particular event and include the hashtag #RealEstate, anyone searching for that term will be able to find all tweets that include it. This feature not only helps with visibility but also enhances engagement by connecting users with shared interests.

The other symbols serve different functions on the platform: the @ symbol is used to tag other users in tweets, the asterisk (*) typically doesn’t have a specific application on Twitter, and the exclamation point (!) is not a searchable element within the context of Twitter. Thus, using the hashtag is essential for promoting content or discussions under specific themes effectively.
