The History of the Hashtag

Where did the hashtag come from? It looks like the hashtag came into existence sometime around the 14th century. Before it was used on telephones and Twitter, the hashtag came from “lb,” the Latin abbreviation for “pound.”

So we (in the U.S.) called it the pound sign for a while.

According to dictionary.com, the hashtag’s official name is the octothorpe, a name invented by telephone technicians when they added the symbol to telephone key pads.

It wasn’t called hashtag until its usage became popular on social media.

The hashtag's usage as a way to find posts about a common topic comes from the below tweet from 2007, suggesting that people used hashtags to create groups on Twitter.

From there, the hashtag began to build momentum, eventually becoming the social media marketing powerhouse it is today.

Now, let's talk about how to use hashtags on each social media platform, starting with Facebook.

How to Use Hashtags on Facebook

Using hashtags on Facebook can get your posts more exposure, but you have to use them the right way.

Here are some tips for using hashtags on Facebook:

  1. Don't use too many hashtags. That will make your business look annoying and/or spammy. Instead, go for 1-2 hashtags per post for the best engagement. If you use more than two hashtags in a Facebook post, you'll see less engagement.
  2. Make your Facebook post public (and make sure to allow people to follow you). Otherwise, only friends and followers will see your posts with hashtags. When you make your Facebook post public, it will allow anyone to see the post if they search for a hashtag that you've included in a post.

How to Use Hashtags on Twitter

Tweets with hashtags tend to get double the engagement of tweets without hashtags. But, as usual, there are rules about using hashtags on Twitter, including how to use hashtags in Twitter ads.

  1. Tweets with 1-2 hashtags get 21 percent more engagement, so don't go overboard. Just a couple of hashtags in your tweet should do the trick.
  2. Tweets with hashtags receive more retweets, but tweets that specifically ask followers to "retweet" (not "RT" - you have to spell it out) will get you even more retweets!
  3. Be careful using hashtags in ads on Twitter. You'll probably get more ad clicks if you don't use a hashtag.
  4. Twitonomy is a great resource to find analytics for trending hashtags.

How to Use Hashtags on Instagram

If it seems as if the sweet spot across all social media platforms is 1-2 hashtags, this is not the case on Instagram. That's probably why so many Instagram posts have seemingly endless hashtags.

Here are some tips for using hashtags on Instagram:

  1. Always use hashtags on Instagram. You'll get 12.6 percent more engagement on average.
  2. You can go a little hashtag wild since Instagram posts with 11 hashtags get more engagement than posts with zero hashtags.
  3. In this case, more might just be better. According to Hootsuite, you can use up to 30 hashtags on Instagram.

 

How to Use Hashtags on Google+

Hashtags on Google+ are different than hashtags on other platforms. They'll still help you reach more people than posts that don't include hashtags, but that's where the similarities end. Here's what you should know about hashtags on Google+:

  1. Hashtags have a greater influence on Google+ than other platforms. If you want to get more engagement on Google plus, hashtags are the key.
  2. If you search for a hashtag on Google, you may see a sidebar that shows Google+ posts related to your search.
  3. There isn't a lot of research on Google+ hashtags, so go for 1-3 hashtags on Google+.

How to Use Hashtags on LinkedIn

LinkedIn hasn't always supported hashtags, but, LinkedIn hashtags are back. You can use them in pretty much the same way you'd use a hashtag anywhere else.

People can search for hashtags on LinkedIn in the same way they can on other platforms, and LinkedIn uses hashtags to monitor what's important to users so it can show them more relevant content.

This is how you should use hashtags on LinkedIn:

  1. Add hashtags to your business's profile to give you more visibility on the networking site.
  2. If you write LinkedIn Pulse (LinkedIn's blogging platform) articles, add some relevant hashtags to the body of your article.
  3. Because this is a newer feature, there isn't a lot of research on how many hashtags to use on LinkedIn, so just stick to the 1-2 rule for now. That should give you more exposure without making you look like spam. We'll keep you updated if this changes or new research surfaces.

More Tips for Using Hashtags for Social Media Marketing

I asked our Digital Content Manager, Meg Hudson, for her top tip when it comes to hashtags on social. She said that branded hashtags are the way to go.

"Come up with something short and memorable that your customers/clients can use on their posts about you so that when you search for your hashtag, you have all of this great user generated content."
