If you spend any amount of time on the internet, you’ve probably seen people using words or phrases with pound signs in front of them, #like #this. On Twitter, this is called a hashtag.
Putting that symbol in front of a word turns it into a searchable link. In other words, you can then click on that #hashtag and see the tweets of everyone else also using it. It’s a way to find people talking about the same thing you’re talking about; it creates a larger conversation all in one feed.
How to Make One
There’s no trick to making a hashtag. You don’t have to register it, log it, or reserve it. All you do is type it, and Twitter will automatically turn it into a clickable search term.
Start with the pound sign (#), but don’t include any spaces or special characters (?’!&, etc.). Spaces and special characters will break your hashtag.
So if you want to use the phrase “author’s choice,” you would need to write it as: #authorschoice or #AuthorsChoice . Neither #author’schoice nor #authors choice will work properly. Some people use caps to make new words easier to read, but this is optional.
Numbers are okay, but don’t start your hashtag with numbers. #2013Conference won’t work. #Conference2013 will, though.
And lastly, don’t forget to keep it short. Hashtags do count toward your 140-character tweet limit, so the longer they are the less space you have to add other text.
