Hashtags may appear as a bizarre combination of words and phrases put together with the # sign before it, but they are vital for expanding your online visibility – if used properly of course. 

Do you still find yourself perplexed about the significance of hashtags?

Why are you seeing them in (almost) every post across social media platforms?

How many hashtags are too many?

Let’s get these concerns straightened out. In this article, discover how hashtags are meant to be used and why you should start using them for your online presence.

It all began when Chris Messina tweeted in August 2007, proposing the use of # (the hash or number sign) to tag topics of interest. Two years later, Twitter started hyperlinking hashtags so that when you click on a hashtag, you are redirected to the search result page showing all tweets bearing the hashtag.

Now fast forward 12 years, popular social media channels have adopted the use of hashtags although the level of success is varied. They have simplified the search for posts and contents with a specific theme as well as helped monitor online discussions. So, what’s in it for you, your brand and business?

What are “the hashtags” for and why use them?

From a marketing and user point of view, hashtags improve your social media visibility.

Increase social media views and grow your followers

A study carried out by Simply Measured showed that posts with at least one hashtag have about 12.6% more engagement than those without.

Take Instagram for instance, this visual-centric platform creates a gallery of photos and videos for every hashtag.

The more hashtags you use, the more galleries your images and videos will appear in. These maximise the number of views and user engagement.

Expand your brand reach outside your network

Making your profile and posts public will allow the whole world to see it.

Your post with hashtags will display in the search results and galleries.

People who are not your followers, but are otherwise interested in the topic will be able to view your post.

If it garners a massive amount of engagement, it will be on top of the lists and trends.

Apart from increasing company involvement and spreading positive attitude (and good vibes!), you are also gaining marketing experience.

Inspire, join the conversation and bring value to the community, don’t just post industry-related content.

How to use hashtags properly on social media

The purpose of hashtags is generally to simplify content discovery, making information searchable and accessible on social media. However, each platform has different rules for using hashtags. Too many and irrelevant hashtags can seem spammy and can hurt your brand’s good name.

Customarily, hashtags must not contain any spaces – even in hashtags with multiple words. You can capitalise the letters to improve readability but you cannot use punctuation marks or it will break the tagging. On the other hand, if your hashtag is part of a sentence, you can use a comma, period, question mark or other punction marks to improve the grammar.


To reiterate, hashtags on Twitter are used to index keywords or topics. Popular hashtags are displayed in Trending Topics.

Tweets with hashtags are 33% more likely to get retweeted than tweets without hashtags.

You can use as many hashtags as you want but it’s recommended to use no more than two hashtags. Tweets with one hashtag are 69% more likely to get retweeted than those with two.


Each hashtag gallery on Instagram has two sections: “Top” for the most popular ones and “Recent” for the freshest posts bearing the hashtag.

Although this platform is tailored for hashtags, you are only allowed to use 30 hashtags in every image or video post.

Do hashtags matter on Facebook? Yes.

It may look like that hashtags are not actively used on Facebook compared to Twitter and Instagram, but they function just the same.

Hashtags turn words and phrases into clickable links, giving you access to relevant topics and public conversations.

When you click a hashtag, you will find a feed of public posts (including posts of your friends and followers) that contain such hashtag. You can even see some related hashtags at the top of the page.


Hashtags maximise your exposure on LinkedIn and build up your network.

The platform proactively promotes hashtags to their users when posting updates and publishing an article.

You can type in the hashtags in the search box to look for relevant topics and articles.

There’s no limit in using hashtags also but it’s advisable to include no more than five hashtags in a single post. Before you select your hashtags, find out what hashtags LinkedIn influencers in your niche are using and explore popular hashtags (see screenshot below).

Apart from hashtags, learn how to enhance your LinkedIn profile to represent yourself and engage online in a way that can help achieve your professional goals.


Hashtags are used on YouTube to look for videos for topics that you’re interested in.

You can insert up to 15 hashtags in your video post. They can be added either in the title or description, or both.

Users will be able to click the hashtags in the video title. Be warned that over-tagging and the use of unrelated hashtags may result in the removal of your video.


Hashtags in Pinterest – which may not be as frequently used compared to other social sites – have a slightly different function.

When you click on a hashtag, you will discover related Pins with the newest Pins at the top.

You can only use hashtags in the pin description because hashtags located in the account and board descriptions and board titles are not clickable.

Not more than 20 hashtags per Pin is highly recommended.
