(MAUs stands for Monthly Active Users, and MUVs stands for Monthly Unique Visitors.)
1. Facebook – 2.23 billion MAUs
Facebook is the biggest social media site around, with more than two billion people using it every month. That’s almost a third of the world’s population! There are more than 65 million businesses using Facebook Pages and more than six million advertisers actively promoting their business on Facebook, which makes it a pretty safe bet if you want to have a presence on social media.
It’s easy to get started on Facebook because almost all content format works great on Facebook — text, images, videos, live videos, and Stories. But note that the Facebook algorithm prioritizes content that sparks conversations and meaningful interactions between people, especially those from family and friends. If you want to learn more about succeeding with the updated Facebook algorithm, Brian Peters, our Strategic Partnership Marketer, shared the secrets of the new algorithm and what you can do to thrive on Facebook.
Also, remember to optimize your content for mobile as 94 percent of Facebook’s users access Facebook via the mobile app.
2. YouTube – 1.9 billion MAUs
YouTube is a video-sharing platform where users watch a billion hour of videos every day. To get started, you can create a YouTube channel for your brand where you can upload videos for your subscribers to view, like, comment, and share.
Besides being the second biggest social media site, YouTube (owned by Google) is also often known as the second largest search engine after Google. (So if you want your brand to be on YouTube, I would recommend reading up on YouTube SEO.)
Finally, you can also advertise on YouTube to increase your reach on the platform.
3. WhatsApp – 1.5 billion MAUs
WhatsApp is a messaging app used by people in over 180 countries. Initially, WhatsApp was only used by people to communicate with their family and friends. Gradually, people started communicating with businesses via WhatsApp. (When I was in Bangkok to buy a new suit, I communicated with the tailor via WhatsApp.)
WhatsApp has been building out its business platform to allow businesses to have a proper business profile, to provide customer support, and to share updates with customers about their purchases. For small businesses, it has built the WhatsApp Business app while for medium and large businesses, there’s the WhatsApp Business API. Here are some stories of how businesses have been using WhatsApp.
4. Messenger – 1.3 billion MAUs
Messenger used to be a messaging feature within Facebook, and since 2011, Facebook has made Messenger into a standalone app by itself and greatly expanded on its features. Businesses can now advertise, create chatbots, send newsletters, and more on Messenger. These features have given businesses a myriad of new ways to engage and connect with their customers.
If you are thinking about using Messenger for your business, here are seven ways you can use Messenger for your marketing.
5. WeChat – 1.06 billion MAUs
WeChat grew from a messaging app, just like WhatsApp and Messenger, into an all-in-one platform. Besides messaging and calling, users can now use WeChat to shop online and make payment offline, transfer money, make reservations, book taxis, and more.
WeChat is most popular in China and some parts of Asia. If you are doing business in those areas (where social media platforms like Facebook are banned), WeChat could be a good alternative.
6. Instagram – 1 billion MAUs
Instagram is a photo and video sharing social media app. It allows you to share a wide range of content such as photos, videos, Stories, and live videos. It has also recently launched IGTV for longer-form videos.
As a brand, you can have an Instagram business profile, which will provide you with rich analytics of your profile and posts and the ability to schedule Instagram posts using third-party tools.
To help you get started and succeed, here’s our complete guide to Instagram marketing.
7. QQ – 861 million MAUs
QQ is an instant messaging platform that is extremely popular among young Chinese. (It is used in 80 countries and also available in many other languages.) Besides its instant messaging features, it also enables users to decorate their avatars, watch movies, play online games, shop online, blog, and make payment.
I have to admit I don’t know much about QQ but Carrie Law from ClickZ has written a helpful brief introduction to QQ for marketers. It seems that while QQ, a desktop-native platform, used to be the top social media platform in China, WeChat, a messaging app from the same parent company, has taken over its place.
8. Tumblr – 642 million MUVs
Tumblr is a microblogging and social networking site for sharing text, photos, links, videos, audios, and more. People share a wide range of things on Tumblr from cat photos to art to fashion.
On the surface, a Tumblr blog can look just like any other websites. So many blogs that you come across online might be using Tumblr!
If you want to consider Tumblr for your marketing, Viral Tag has written a starter guide to Tumblr marketing.
9. Qzone – 632 million MAUs
Qzone is another popular social networking platform based in China, where users can upload multimedia, write blogs, play games, and decorate their own virtual spaces.
According to several people on Quora, Qzone seems to be more popular among teenagers (while WeChat is more popular among adults). But the rise of mobile-based platforms like WeChat seemed to have caused a decline in popularity of desktop-based platforms like Qzone.
10. Tik Tok – 500 million MAUs
Tik Tok (also known as Douyin in China) is a rising music video social network. It was the world’s most downloaded app in the first quarter of 2018, beating Facebook, Instagram, and other social media apps.
My initial impression is that it looks like Instagram for short music videos (though I’m sure it’s more than that). Users can record videos up to 60 seconds, edit them, and add music and special effects.
While it is most popular in Asia, my hunch is its popularity might spread to the west. It has recently acquired Musical.ly, a similar music video social network where Coca-Cola once did a successful “Share a Coke and a Song” campaign.
11. Sina Weibo – 392 million MAUs
Sina Weibo is often known as Twitter for Chinese users (since Twitter is banned in China). It has features similar to Twitter — 140-character microblogging, uploading of photos and videos, commenting, and verification of accounts.
If you would like to learn more about Sina Weibo, What’s on Weibo, a social trends reporting site, wrote a helpful short introduction to Sina Weibo.
12. Twitter – 335 million MAUs
Twitter is a social media site for news, entertainment, sports, politics, and more. What makes Twitter different from most other social media sites is that it has a strong emphasis on real-time information — things that are happening right now. For example, one of the defining moments in the Twitter history is when Janis Krums tweeted the image of a plane that landed in the Hudson River when he was on the ferry to pick the passengers up.
Another unique characteristic of Twitter is that it only allows 280 characters in a tweet (140 for Japanese, Korean, and Chinese), unlike most social media sites that have a much higher limit.
Twitter is also often used as a customer service channel. According to advertisers on Twitter, more than 80 percent of social customer service requests happen on Twitter. And Salesforce calls Twitter “the New 1-800 Number for Customer Service“. There are many social media customer service tools, such as Buffer Reply, available now to help you manage social customer service conversations.
13. Reddit – 330 million MAUs
Reddit, also known as the front page of the Internet, is a platform where users can submit questions, links, and images, discuss them, and vote them up or down.
There are subreddits (i.e. dedicated forums) for pretty much anything under the sun (and above). Subreddits, however, have different levels of engagement so it’s great to research to see if there are popular subreddits that your brand can be part of. For example, r/socialmedia tends to be pretty quiet so we are rarely on Reddit.
14. Baidu Tieba – 300 million MAUs
Baidu Tieba is a Chinese online forum created by Baidu, the largest Chinese search engine in the world. My interpretation of Wikipedia’s description is that Baidu Tieba seems to be similar to Reddit, where users can create a forum thread on any topic and interact with one another.
15. LinkedIn – 294 million MAUs
LinkedIn is now more than just a resume and job search site. It has evolved into a professional social media site where industry experts share content, network with one another, and build their personal brand. It has also become a place for businesses to establish their thought leadership and authority in their industry and attract talent to their company.
To help you grow your LinkedIn Company Page follower, we have written a blog post covering a simple five-step strategy.
LinkedIn also offers advertising opportunities, such as boosting your content, sending personalized ads to LinkedIn inboxes, and displaying ads by the side of the site.
16. Viber – 260 million MAUs
On the surface, Viber is quite similar to major social messaging apps such as WhatsApp and Messenger. It allows users to send messages and multimedia, call, share stickers and GIFs, and more.
However, Viber presents many more opportunities for businesses. As a business, you can buy ads, promote your brand through stickers, engage your community, display your products in the shopping section, and provide customer service.
17. Snapchat – 255 million MAUs
Snapchat is a social media app that focuses on sharing photos and short videos (as known as snaps) between friends. It made the Stories format popular, which eventually proliferated on other social media platforms like Instagram. But the rise of Instagram Stories seemed to have hindered Snapchat’s growth and marketers’ interest in using Snapchat for their brands in general.
If you are not familiar with Snapchat, here’s our beginner’s guide to Snapchat. Or if you are undecided between Snapchat and Instagram, we wrote a little comparison of Snapchat and Instagram for brands.
18. Pinterest – 250 million MAUs
Pinterest is a place where people go to discover new things and be inspired, quite unlike most social media sites where engagement is the primary focus. According to Pinterest, 78 percent of users say that content on Pinterest from brands are useful (much higher than that on other sites). This gives your brand an unique opportunity to shape their purchasing decisions.
As Pinterest users want to be inspired to try or buy new things, having a presence on Pinterest could help put your brand on their minds. Here are some tips on using Pinterest for business that the Pinterest team shared with us.
19. Line – 203 million MAUs
Line is a multi-purpose social messaging app that allows users to message, share stickers, play games, make payments, request for taxis, and shop online. It is the most popular messaging app in Japan and is also popular in other areas in Asia.
Brands can create official accounts on Line to share news and promotions, which will appear on their followers’ timeline.
20. Telegram – 200 million MAUs
Telegram is similar to most social messaging apps and is often known for how secure it is as a messaging app.
There are several ways brands can make use of Telegram, besides providing one-on-one customer support. For example, brands can create chatbots for the Telegram platform or make use of Telegram’s channel feature to broadcast messages to an unlimited number of subscribers.
21. Medium – 60 million MAUs
Medium is an online publishing platform with a social network element. It’s free to publish on Medium and free to read most articles. Some articles are reserved for only paying members.
Besides publishing original content on Medium, it’s quite common for brands to republish their blog posts from their company blog onto Medium to extend their reach. (That’s what we’re doing here at Buffer.)
If you want to experiment with Medium, we wrote a guide to Medium for marketers and a blog post on the nine strategies we tried on Medium.
