Privacy settings are still in effect
If you’re using hashtags on posts on your personal profile, they’ll still have the privacy settings set up according to how you control your privacy on your profile. Just because you use a hashtag doesn’t make that post suddenly public. If you add a hashtag to a post that you only share with a certain group of your friends, only that group will be able to see that post.
Hashtags have to be all one word
If you wanted to use #Facebook Marketing as your hashtag, it will need to be posted as #FacebookMarketing or #facebookmarketing (see the next tip).
Capitalisation doesn’t matter
You can choose whatever capitalisation you want in the words themselves and the hashtags will show the same results. #FacebookMarketing and #facebookmarketing show the same search results.
You can make up whatever hashtags you want
There’s no “hashtag registration” or “database of approved hashtags”, you can make up whatever hashtags you want to use. Consider your goals. If you want to brand your own hashtags, you can, but make them short and easy to use and understand.
A hashtag that’s overly complex or hard to read won’t get much traction. If you’re abbreviating, make sure it’s clear what point you’re going for – a hashtag like #IKPMTTTRWD won’t mean much to many people.
Research your hashtag before you use it
There have been some recent embarrassing cases of brands using a hashtag that’s already in use for an entirely different purpose that doesn’t align with their company message at all. Take a look at the social sites where hashtags are in use such as Pinterest, Twitter, Instagram and Google+ and see if your hashtag is already being used by people.
You can easily look for hashtags on Facebook by URL
Easily search for hashtags or bookmark their results by using the URL: http://www.facebook.com/hashtag/ then just include your keyword on the end.
For example https://www.facebook.com/hashtag/FacebookMarketing shows you the results of posts that include #facebookmarketing or #FacebookMarketing (or any alternate capitalisations).
