A hashtag is the pound sign # followed by a tag that explains what the topic is that you’re writing about. If I’m writing about the economy, I might write #economy within my tweet. If I’m writing about Indianapolis, it might be #indy. If you’re utilizing Twitter for business, effective use of hashtags is a must.
Ever wonder who used the first hashtag? You can thank Chris Messina in 2007 on Twitter!
