Hashtags: What They Are and How to Find Them
The hash mark (#).
We’re all used to seeing it as an abbreviation for weight, as in “I’d like a 2# bag of onions” or for numbers like “World’s #1 Dad”. And of course you’ve probably used it on the phone when you’re trying to figure out the non-human customer service menu at a large company, “enter your account number followed by the pound sign (#)”.
What is a Hashtag?
But on Twitter hash tags are a whole new experience. On Twitter we use hash marks to help identify, organize and track topics online. We add the mark to the beginning of words so it creates a searchable phrase. What types of things can be made into a hashtag? Virtually anything.
Here are some common Hashtag uses:
- Events – An event that a group of people is attending or celebrating, either locally, regionally, globally, or virtually.
- Topics – Any topic that you may have an interest in exploring.
- Marketing = #marketing
- Photography = #photography
- All things earth-friendly and green = #green
- Follower suggestions – Recommendations that users make about who to follow on Twitter.
- Follow Friday = #FollowFriday or #FF
- Eco Monday = #EcoMonday
- Online Chats – Coordinated times when people gather online to discuss a particular topic or common interest.
- #SMCNHchat = Social Media Club of NH. Discussing the group and related topics within New Hampshire’s Social Media circles. Sunday’s, 9 PM.
- #agchat = Agriculture chat to maintain ongoing open dialogue in agriculture. Tuesday’s, 7 PM
If you already know the hashtag to follow then you can simply put it into the search bar on Twitter and listen in to what the Tweet stream is sharing. If you don’t know what you’re looking for, you can identify hashtags using a variety of different tools.
Finding a Hashtag
The easiest way of learning about a hashtag is to ask. If you’re at an event, ask what the official hashtag is and use it. If you’re online and notice a hashtag that you aren’t familiar with, ask a Tweep using it what it is, or follow the hashtag for a while and most likely you’ll be able to get an idea of what the topic is about after only a few minutes.
If you want a more direct approach, try searching for the hashtag using tools like Twubs, Tagalus, and What the Hashtag?! (just recently purchased by What the Trend). These are directories where you can search to find out what a hashtag is or browse categories of hashtags to see what might be of interest to you.
If you’re looking for a chat schedule, Google maintains a wikipedia like spreadsheet of chats called Twitter Chats where you can find over 300 different chats that are regularly scheduled and open to follow. You can also follow @twchat on Twitter to learn about new chats as they are organized. If you want to know more about the hashtag itself other than listening in to the conversation, check out hashtag.org to see the volume and trending pattern.
