How hashtags work on Buffer's web application (

When using Buffer on our web application (, the autocomplete function only works for Twitter. 

📝 What is autocomplete? The autocomplete function presents a list of potential hashtag options based on the hashtag you start typing. These hashtags will be the ones that Twitter believes are most relevant to you based on the activity on your Twitter account.

On Facebook, Instagram, LinkedIn, and TikTok, you can add any hashtag manually, and the hashtag will be hyperlinked once the post is published to the platform.

Pinterest does not hyperlink hashtags, so hashtags sent to Pinterest will not be clickable.

How hashtags work on Buffer's mobile app

Buffer's autocomplete feature works for all social channels: Instagram, Facebook, Twitter, LinkedIn, TikTok, and Pinterest.

When the post is published, the hashtags on Facebook, Instagram, LinkedIn, and TikTok posts will hyperlink just as if they were sent from the Buffer web application or from the native platform itself.

Pinterest does not hyperlink hashtags, so hashtags sent to Pinterest will not be clickable.

Using Buffer's hashtag manager

If you're on any of our paid plans, you'll have access to the hashtag manager, allowing you to create groups of hashtags to quickly insert into the caption of any post you send to any social account through Buffer.

There is no autocomplete functionality within the hashtag manager, so it'll be important to double-check that all of your hashtags are spelled as you'd like them to be. However, you have the option to edit your hashtag groups at any time on mobile (Android or iOS) or on the web.

Below are the steps to use the hashtag manager.

  1. You'll click the # symbol first.
  2. If you haven't yet created any hashtag groups, click Create Hashtag Group. Enter a name for your group and add the hashtags you'd like to include. Toward the bottom of the content area, you'll be able to see how many hashtags you have remaining so that you don't exceed Instagram's limit of 30 hashtags per post. Once you're happy with your hashtags, click Save Hashtag Group. (Groups can be edited or deleted by hovering over the group and clicking the three dots on the right-hand side. To delete a group, click Delete Group.)

  3. You'll now see all of your groups listed in the hashtag manager. To add a group of hashtags to your post, place your cursor where you'd like to add your hashtags in the caption, hover over the group and click Insert. You are able to insert multiple groups, but keep an eye on the hashtag counter to make sure you don't exceed Instagram's limit of 30 per post.


  • The hashtag manager is universal across your team. If you have multiple users in your organization, the hashtag groups that you create and save will be available for everyone to use.
  • Based on Instagram's advice, hashtag groups are best suited to populate into the caption/composer for the purposes of reach. However, if you'd prefer to add hashtag groups to the first comment instead, you can do that by cutting them from the caption/composer and pasting them into the first comment area.
