Hashtag Basics

Here are a few quick rules for how to use hashtags:

If you’re using hashtags for their intended purpose (categorization and discovery), don’t string too many words together with a single hashtag.
On most networks, if you use a hashtag on a public account, anyone who does a search for that hashtag can find your post.
Don’t #spam #with #hashtags. Avoid over-tagging a single post or adding them to every word.
Tweets with hashtags had 2 times more engagement than those without, and 55% more Retweets.
Use hashtags only on Tweets relevant to the topic. Trying to get attention by using a mismatch between the content of your Tweet and hashtag use won’t do you any favors if people are annoyed.
