Want to get noticed on Twitter? Use hashtags! Using the right hashtag(s) in your tweets will bring you the relevant audience and exposure. This is also with those that you will be able to follow conversations known as chats.
How to use hashtags efficiently? How many is too many? Let's have a look at hashtags best practices on Twitter.
1. More than 3 is too many.
Social media professionals all seem to agree that 3 is the maximum number of hashtags that you should include in one tweet. Don't overwhelm your followers with too many hashtags. Instead, choose them well, the more relevant the better.
2. Stay away from irrelevant popular hashtags.
Yes, they are widely used for a reason, and you'd like to jump on that wagon. But if your tweet has nothing to do with the hashtag you use, as trending as it is, you or your brand will become instantly irrelevant to both your current and potential followers.
3. Size does matter.
When it comes to hashtags, the shorter the better. First, it will save you space in your tweet. 140 characters are not a lot, so don't use half of those for your hashtag only. Two to three words are enough, no need to make a full sentence out of it. Use capital letters for each words so it's easier to read.
4. Go specific.
Stay away from hashtags that are too general. Using #marketing or #business in your tweets won't bring you more exposure as they are widely used words. Target specific conversations instead with hashtags like #TwitterTips or #NativeAdvertising, depending on your topic. Creating a hashtag for yourself or a specific campaign is tempting. It has to be well advertised and shared though so you are sure it is used correctly... or used at all!
5. Do a pre search
Search the hashtag on Twitter first to see if it is used and by who. What kind of conversations does the hashtag trigger? Is it where you want to go?
