How Many Hashtags Should You Use for Each Social Platform

June 21, 2021

Marketers know the value and power of hashtags on social media. Hashtags are best known for their ability to connect posts and conversations through clickable links and show your content to others' feeds, even to those who don’t follow you – yet.

Now that we've established the importance of hashtags, how do you know the right number of hashtags for each social media platform? There seems to be no definite guide about this, so we created one – and you’re reading it now.

In this guide, we will cover all major platforms and discuss how many hashtags you can use and where you can use them.


Although hashtagging started on Twitter, Instagram took it to new heights and made its popularity soar among users.

Where Can You Add Hashtags on Instagram?

You can add hashtags to your Instagram bio, captions, and Reels. Some users also add hashtags in Instagram Stories.

Instagram Bio

As you may know, Instagram limits bio characters to 150, which means you have limited space to add hashtags. After writing the description, if you see that you’re left with some space, add your campaign or branded hashtags there.

Let’s take a look at the official Instagram page of Michael Kors. Note that the company added its branded hashtag, #MichaelKors, to the bio.

Another interesting example is from Adidas, which obviously believes its bio is best reserved for its campaign hashtag, #ImpossibleIsNothing.

Instagram Reels and Posts

When you’re hashtagging on Instagram Reels and posts, the maximum number of hashtags you can use is 30. The same is applicable to comments.

While some believe 11 hashtags should be the maximum, we’ve seen many posts and accounts (including ours – @hashtagexpert) that do well and achieve higher engagement and views with 30 hashtags.

Instagrammers are accustomed to seeing hashtags so there is no problem if you use all 30.

Instagram Stories

You can use up to 10 hashtags in Stories.


Hashtags on TikTok work like they do on other platforms but are not clickable. That doesn’t mean hashtags aren’t useful. By using the right hashtags, you can take your videos to the TikTok For You and Make Your Day feeds.

Where Can You Add Hashtags on TikTok?

With just 80 characters, TikTok makes it difficult to place hashtags in your bio. So the obvious next option is the captions.

How Many Hashtags Can You Use on TikTok?

There is no limit to using hashtags on TikTok, but the one constraint is characters. You only have 100 characters in which to fit in your caption and add hashtags.

To make the most of TikTok hashtags, keep your caption short so you can save more space for adding hashtags.


Hashtags have been used on LinkedIn since 2016, but the concept is still new to many users. Here's an informative article that answers many questions about using hashtags on LinkedIn.

The official LinkedIn blogs actively encourage their community members to use and follow hashtags to shape conversations and insights to their feed.

Where Can You Add Hashtags on LinkedIn?

LinkedIn Articles and Posts

There is no official limit to the number of hashtags you can use in a LinkedIn post or an article. We recommend, however, that you limit each post to a maximum five to seven hashtags, with an absolute maximum 10 hashtags.

This is because LinkedIn operates differently from other social networking sites, namely Instagram. To learn more about this and what types of hashtags work best on LinkedIn, we recommend our guide, "How to Increase Your Exposure With LinkedIn Hashtags."

LinkedIn Profile

You can add hashtags to your profile description and there is no limit. But make sure your hashtags don’t make it look cluttered or spammy; less is more in this case.

Another way to add hashtags on LinkedIn and show them on your profile is through Creator Mode. Creator Mode is a new enhancement to LinkedIn’s features. It allows you to add up to five topics in the form of hashtags. These topics are displayed on your profile to show potential followers what you post about most.


A lesser known fact for many YouTubers is that hashtags can significantly improve visibility of their videos. Hashtags work like keywords on YouTube – which means they help improve YouTube SEO.

Here's an excellent example of hashtags being used on a YouTube video description:

YouTube videos are shown not only inside the platform, but all across search results on Google. So now comes the next question ...

Where Can You Add Hashtags on YouTube?

Google actively promotes the use of hashtags on YouTube and asks that they be used in titles and descriptions. According to Google's Hashtags on YouTube guide:

  • Hashtags in the title and description will be hyperlinked.
  • If there are no hashtags in the title, the first three hashtags in the description will show below the video title.

According to Google's Hashtag Use Policies, using more than 15 hashtags can lead to limited visibility and/or removal of that video from uploads or search. It adds: “The more tags you add to a video, the less relevant they become for viewers who are searching.”


Hashtagging on Twitter is nothing new – in fact, it all started there. On August 23, 2007, former Google developer and San Francisco techie Chris Messina tweeted with the very first hashtag that was ever created.
