Definition: The # symbol, called a hashtag, is used to mark keywords or topics in a Tweet. It was created organically by Twitter users as a way to categorize messages.
I remember when the [#] hashtag was known as the pound key or the number sign and we all long for the days when it was just referred to as a Tic-Tac-Toe board! However this obscure sign plays a crucial role in social media communication. One must embrace this key and utilize it on almost every Twitter and Pinterest post.
One of the key ways to grow your social media following organically is through the use of [#] hashtags. When someone does a topic search on Twitter the computer algorithm is looking for the key-words attached to [#] hashtags.
Hashtags: Categorizing Tweets by Keyword
- People use the hashtag symbol # before relevant keywords (no spaces) in their Tweet to categorize those Tweets and help them show more easily in Twitter Search.
- Clicking on a hashtagged word in any message shows you all other Tweets in that category.
- Hashtags can occur anywhere in the Tweet – at the beginning, middle, or end.
- Hashtagged words that become very popular are often Trending Topics.
Example: If you are sending out a tweet of a leadership article from the Harvard Business Review, the two hashtags you might consider using are #leadership and #management. You could add a [#] hashtag for #HBR but I would prefer to give them props by adding (via @HBR) to the end of my tweet or LinkedIn post.
#FF: Users created this as shorthand for “Follow Friday,” a weekly tradition where users recommend people that others should follow on Twitter. You’ll see this on Fridays. I have had someone do a #FF on me and it grew my followers by 25 in one day.
Using Hashtags Correctly:
- If you Tweet with a hashtag on a public account, anyone who does a search for that hashtag may find your Tweet
- Don’t #spam #with #hashtags. Don’t over-tag a single Tweet.
- Two [#] hashtags per Tweet is a good recommendation.
- Use hashtags only on Tweets relevant to the topic.
