Hashtag
Social Media Hashtag
A word or phrase preceded by # used to categorize content and make it discoverable on social platforms.
技术细节
Hashtags are indexed by social platforms for content discovery. Each platform has different optimal strategies: Instagram benefits from 3-5 specific hashtags per post, Twitter recommends 1-2 hashtags for engagement, and LinkedIn penalizes posts with more than 3-5 hashtags. Hashtags should be specific to the content rather than generic — #PythonDjango outperforms #coding in reaching the right audience. Branded hashtags create trackable campaign performance metrics.
