Twitter Hashtags

[Lishmalinyjames]

People use the hashtag symbol (#) before a relevant keyword or phrase in their Tweet to categorize those Tweets and help them show more easily in Twitter search.
Clicking or tapping on a hashtagged word in any message shows you other Tweets that include that hashtag.
Hashtags can be included anywhere in a Tweet.

Tools like Hootsuite and Sprout Social give solid hashtag analytics and competitor tracking. Optimal density is 2 hashtags max, otherwise you dilute engagement metrics and hurt visibility in feed ranking.
