Algorithms of the Top 4 Social Media Channels defined

Algorithms of the top 4 social media channels

There was a time when the social media feed was purely chronological, and posts appeared according to their publishing date and time. There were no promoted elements in the feed citing user affiliations or interests.

Furthermore, no posts were kept off the feed just because user interaction was minimal or zero with previous posts from the author in the past.

Things changed drastically once social media algorithms were introduced.


Presently, all social media sites use algorithms.

Algorithms are a mathematical set of rules to manage data. Social media algorithms are mathematical patterns devised & followed by sites to customize the users' experience.

These algorithms rank the posts according to relevance and not just according to the time they were posted on. This is done by gauging the engagement pattern of the users.

While it is seen as manipulative by some, the intention is solely to optimize the social media experience. For social media marketing, it poses a challenge for organic growth but aids in paid marketing campaigns.

Here we will delve into the algorithms of the top 4 social media platforms: Facebook, Twitter, LinkedIn, and Instagram:

1. Facebook

On an average, 1.62 billion people visit Facebook every day across the globe. You can imagine the sheer amount of engagement occurring on the platform. Facebook is also used by brands for marketing & promotions. So, the fight for getting that valuable spot in the newsfeed is intense.

Facebook's algorithm is always changing, but it sticks to the core values of personal connection and meaningful engagement. The Facebook feed prioritizes some basic rules:

Author of the post: Who posted is an important question for Facebook. If there has been recent engagement with a post in the form of sharing, like, comment or even reading, then Facebook displays posts from that author in your feed. Whether you follow this account or not, engagement history matters. Old friends might just vanish from your feed if you have not interacted with them for a long time.

Engagement value of a post: The more engagement a post has garnered, the more likely it gets that Facebook will show it in the feeds. Facebook presumes such posts to be more interesting and keeps showing it to more people.

Type of posts: If you engage with a certain kind of post, you will see stories of similar kinds. Interests and affiliations play a major role here.

Time of posts: Last but not least, the age of the post is a crucial factor. Recent stories will rank higher whenever you log in the feed.

2. Twitter

Approximately 500 million tweets are sent every day. On Twitter people tend to follow many accounts and the frequency of updates is high. Twitter earlier had a timeline structure, but gradually the total number of tweets became unmanageable to track in a timeline. Hence, algorithms were introduced.

The Twitter algorithm uses two models:

Top tweets: These are the tweets sorted based on engagement parameters. These parameters are of two types. First, the number of retweets, clicks and impressions the tweet has received. Second, the user's engagement with the previous tweets from the same account.

Latest tweets: This model arranges the tweets in reverse chronological order, placing the most recent tweets on the top. To some extent, even this sorting is influenced by relevance factors and not all tweets are displayed in the timeline.

In both models, Twitter utilizes its ranking signals:

  • Time of tweet

  • Tweet content type (rich media preferred, like image, gif, video)

  • Engagement garnered by the tweet (likes, replies, retweets)

  • Tweet author (prominence, connection to the user)

  • User behavior

3. LinkedIn

As the largest professional network in the world, LinkedIn has 310 million monthly active users. It also is the only social networking channel to have published helpful guidance with respect to its algorithms. LinkedIn is all about connections and online networking that help in business. It also is a great platform for B2B marketing.

Just like Twitter, the LinkedIn feed can be sorted by top content or recent content. Choosing top content displays the most popular posts and selecting recent content sorts the feed by date of publishing.

Still, the feed is heavily influenced by an algorithm that can be defined in a few steps as a process:

  • LinkedIn evaluates the post on its content quality and puts it in three categories: spam, low quality & high quality. While filtering for high quality, the grammar, hashtags, tagging and frequency of posts are considered.

  • Once the post passes quality check, the first hour is critical and decides the success of the post. LinkedIn measures the initial engagement and then decides if it can be moved to other people's feed.

Till the time the post keeps receiving sufficient engagement, it stays and gets distributed further.

4. Instagram:

Instagram is the most popular photo & video sharing app, with around 500 million daily active users. It also had a reverse chronological feed till 2016 but included algorithms after that.

Instagram does not hide or refrain content and mostly shows all the posts in the feed. But the rankings are highly influenced by six signals:

Interest: Past engagement analysis with posts, topics, and people.

Timing: The time at which the post was published.

Relationship: Closeness to the person/author of post measured by past interactions.

Frequency: How often the user checks the Instagram feed, since it will try to dish out the best of the posts.

Following: If the number of people being followed is large, then Instagram will pick stories from a wider selection of authors.

Usage: The length of an average session also determines what posts appear in the feed. The longer the duration, the higher the possibility of seeing more posts.


In social media optimization the dynamics of algorithms matter a lot. The average engagement rate on Facebook and LinkedIn is as low as 0.18 % & 0.54 % respectively.

To expand their reach, brands need to understand the algorithms first. Posting quality content regularly is essential, but to receive the deserved engagement, algorithms must be outdone.

Some buzz is initially needed to get noticed by algorithms. This could be in the form of paid marketing campaigns, or very intense organic mobilization. Both would require a lot of planning and effort.
