So, how you use #hashtags with Twitter to identify your keyword? You simply type # before your appropriate keyword but don’t overuse because it makes your tweets hard to read. In short using one hashtag is best—but more than two become risky.
As soon as you find a good, short, intuitive hashtag, make sure you promote it on the web site and in different media so that people know what you are talking about. And also you need to verify your hashtag in Twitter search feed like Hashtag.org to find if your group is already available or not.
