A couple of useful tips to follow:
- You can use one or more hashtags anywhere in your tweet. Twitter recommends using no more than two hashtags per Tweet, but you're free to use as many as you wish.
- Don't use spaces in a hashtag. For example, '#World Cup' would reference the topic of 'World' as opposed to '#WorldCup', which references the 'World Cup'.
- Don't use punctuation in a hashtag. For example, #It'sComingHome won't work, although it’s grammatically correct. Use #ItsComingHome instead.
