Add hashtags to a post
This article covers adding hashtags to your post when posting to social sites.
If you'd like to add hashtags to your post, select your Twitter or Instagram profile and add the symbol "#" in the Compose Box and start typing the hashtag you'd like to add.
Once you have started typing, results will appear in a drop-down list and you can select the specific hashtag you'd like to add.
If you create a post that includes both Twitter and Instagram profiles, when typing a hashtag in the main tab you'll find that the list that appears displays the available hashtags for Twitter. In order to then add hashtags for your Instagram profile, you'll have to switch over to the Instagram tab and add the hashtag there.
