Instagram is a social media platform built for smartphones. You can use it on a computer, but you can't really add posts without using a separate tool.
So, you'll need to download the app and create an account. Next, you'll want to tell Instagram that you are a business so they'll give you analytics on your posts by converting your account to a professional account. And now you're set up and ready to get started!
Here are some terms you should be familiar with:
Post - This is the default type of content you will share. You can share 1-10 photos and/or videos in one post. Videos must be 60 seconds or less.
Feed - These are the posts from the people you follow.
Story - Your story is content that shows up at the top of the Instagram app and remains there for 24 hours. After that it is removed from your profile unless you save it to your highlights. Videos here will be 15 seconds or less.
Reel - This is Instagram's newest feature. These video clips are 30 seconds or less.
IGTV - This is where longer videos go. These can be 1-60 minutes long. Both Reels and IGTV videos can be found by going to an Instagram profile page.
Hashtags - A hashtag starts with the # sign and contains a word or phrase that describes your content and can be used as a search term.
Private Account - Accounts on Instagram can be set to public (the default) or private. Accounts that are set to private must approve followers before they will be able to see their content.
Reposting - Reposting is when you take a post from someone else and post it on your account. This can be done in your stories or as a post.
