How To Mention People, Pages & Hashtags
Tagging A User And Looking Up Hashtags On Instagram
You can type an @username to tag someone, but you will need to know the exact username, as Instagram does not allow searching for users.
You can also add hashtags by typing the # symbol followed by the text for the specific topic you are interested in.
Both the @username and hashtags will become actionable on Instagram, once the post goes through.
If you aren't certain about the @username or hashtags you're using, you can (re)add them manually when copying the caption back in the Instagram App, before finalizing the post.
Mentioning A Page On Facebook
Recently Facebook made a change to how you can mention others. You can only add tags when creating a post for a Page – you cannot add tags for posts to a group.
You'll need to type @pageID to tag a Page. This means that you'll need to know the exact page ID, which you can get from the page’s URL.
If you’ve added a valid page ID (as well as during typing it), a drop-down list will be displayed with options. You can select the page you're tagging from the drop-down, which will confirm that you have the correct one.
This is because Facebook does not allow searching for pages.
You can only tag other Pages – you cannot tag personal profiles or groups.
If you're tagging multiple pages, make sure to select each one from the drop-down before moving to adding/typing the next.Note: Facebook’s API restricts all third-party tools from publishing mentions from Facebook Profiles and Groups. Because of Facebook’s restrictions, you can only mention Facebook Pages from a Facebook Page.
Mentioning An Account And Adding Hashtags On Twitter
You can look up a Twitter profile to mention, by typing an @ symbol followed by a few characters. You can then choose from the matching Twitter profiles.
You can type any #hashtag. While Twitter does not offer hashtag lookups, these will become actionable once the post goes through.
If you're tagging multiple profiles, make sure to select each one from the drop-down before moving to adding/typing the next.
