Hashtags provide a quick and easy way to search, organize, and share information on Twitter.
What are they?
Hashtags can be any word preceded by the # symbol. Using them lets you associate your tweets with a larger topic (e.g., #HIV), group, or conversation.
Why use them?
Adding hashtags to your tweet is like adding keywords that make your message globally searchable. Add them when you are tweeting on a specific topic. You can use hashtags that are already in use to join in on the conversation—or make up a new one to start a new topic.
Hashtags usually refer to such things as:
- Subjects: #HIV , #PrEP
- Events: #AIDS2016 , #NHTD
- Agencies: #NIH , #CDC
- Verbs: #GetTested , #SpeakOutHIV ,
How to create them?
Creating hashtags is easy. Simply put a # symbol in front of the phrase you want your tweet associated with. Here are 2 examples:
If you want your tweet to show up on the Twitter feed showing all HIV-related tweets, simply include #HIV in your post, as in this recent HIV.gov tweet:New SMAIF funding opportunity from @HRSAgov services. Apply by July 12 http://1.usa.gov/294CsFd You can also include a Twitter hashtag as a part of a regular sentence to direct people to a Twitter conversation. Here's how our Black Voices blogger Deondre Moore did it for National HIV Testing Day -
"..join me and many others today as we #SpeakOutHIV . Be engaged and use your social media platforms to encourage friends and family to get tested for HIV. Share with us why it’s important to #KnowYourStatus ."
A few rules for making a hashtag:
- No spaces
- No punctuation or unusual characters (such as currency or punctuation symbols), though underscores are okay.
- Don’t overuse hashtags: Too many in a tweet makes it look like spam and will turn people off.
- Put your hashtag in context: Give a short explanation that includes the hashtag to explain what it’s about.
- Be sure the hashtag adds value: Use them when you need to organize information, such as on a conference, major event, or a reminder.
- Choose a hashtag early if you are organizing an event; make it simple (for example, #AIDS2016 instead of #InternationalAIDSConference), and remind attendees in all your communication about the hashtag.
- For non-Twitter users, provide a conversation tracker tool on your website. You can make one with EverWebWidgetBox or tweetgrid.com .
Where to follow hashtags?
Many tools are available to help figure out which hashtags offer the best chance of being widely seen. Here are a few:
