WHAT IS A HASHTAG?
A hashtag is a word or phrase preceded by a hash sign (#), used on social media websites and applications, especially Instagram and Twitter, to identify messages on a specific topic.
WHY DO WE USE IT?
Hashtags are clickable links which display content with the same hashtag eg. #food
HOW DO I USE HASHTAGS?
When you post content to Facebook, Instagram, Tumblr and Twitter it is important that you add content-specific tags and also location-specific tags. You can have as many tags as you want, however, Twitter cuts messages to 280 characters so put the most important hashtags at the top of the Twitter post.
Firstly, hashtags have no spaces. For example, daily quotes becomes #dailyquotes . If you use a space the link will be cut off, eg. #daily quote, only the daily word will be linked.
Most people frown on using tags that have nothing to do with your post content.
When you post to Instagram, you should add as many relevant hashtags as possible. If you forget or mistype a hashtag you can edit the post (on the app) or add them in a comment. Some people post only text in the top of the description and add their hashtags below, or in the comments for a cluttered approach.
When you add tags to Instagram a list of the most popular tags with the same initial letters will come up. Eg. #food could be #food or #foodblog or #foodporn. It will show how many posts have that tag and this way suggests some tags you might want to use. Other food-based tags for tasty includes #yummy and #delicious
HASHTAGS IN TOP POSTS
I often visit location-based hashtags such as #brisbane and look at the top posts for that keyword. I then look at the hashtags they use and write any down that is related to my content or my location. Eg. #redlandsanyday is a popular one in Redlands Coast and #brisbaneanyday in Brisbane, QLD
