• Facebook,
• Instagram,
• LinkedIn,
• Pinterest,
• Snapchat,
• TikTok,
• X (formerly Twitter),
• and YouTube.

• From Simple to Complex (the genesis of social media algorithms),
• General Mechanics (the components of algorithms),
• Benefits and Risks (the upside and downside of algorithms),
• Algorithm-Savvy Marketing,
• Ethical Considerations,
• The Future of Algorithms on Social Media Platforms, and
• Conclusion

1. User Engagement: Engagement is at the heart of algorithms. The more users interact with specific content, the more likely it is to be promoted within feeds. This initiates a cycle where popular content gains even more prominence.

2. Content Prioritization: Here are examples of how different social media platforms treat content. The terms “advances,” “favors,” and “prioritizes” are used interchangeably.

• Facebook advances live videos.
• Instagram favors images and videos.
• LinkedIn prioritizes thought leadership posts.
• Pinterest advances pins about recipes, home décor, and fashion; and pins that link to external websites such as blogs.
• Snapchat prioritizes content that uses filters and lenses.
• TikTok advances videos that receive high engagement rates within seconds of being posted.
• X increasingly favors videos.
• YouTube prioritizes long videos with high watch times.

3. Content Relevance: Algorithms prioritize content that aligns with users’ preferences and history. For example, if a user frequently engages with fitness-related posts, the algorithm will likely serve them with similar content. That tactic can enhance user satisfaction, but it can also lead to echo chambers. Those are environments that expose users primarily to information that reinforces their existing beliefs.

4. Freshness: Social media thrives on immediacy. Newer content often takes precedence over older posts. That compels brands, influencers, and others to maintain an apt posting schedule.

5. Network Effects: Content gaining traction among a user’s network helps amplify its reach by spreading (more) rapidly, including possibly ‘going viral.’ There is no universal quantification for what constitutes ‘viral,’ but a post with 1 million or more views/impressions may qualify.

1. Personalization: Individuals tend to interact more frequently with content that aligns with their preferences.

2. Content Discovery: Algorithms can facilitate the introduction of content and accounts that users may not have encountered otherwise.

3. Reduced Information Overload: Social media platforms house a massive volume of content. Algorithms may help filter out the noise. By prioritizing relevant posts, algorithms can help individuals to focus on what matters most to them.

4. Enhanced Engagement: As users find more of the content they enjoy, they will likely spend more time on the platform. This increased engagement also benefits platforms as they can monetize the increased time and attention through advertising.

1. Echo Chambers and Polarization: The potential formation of echo chambers is the most concerning byproduct of algorithmic personalization. Users are at risk of being shielded from differing perspectives. That is especially the case with political discourse; those situations can lead to polarization or increased polarization.

2. Risk of Promoting Incorrect Information: The algorithms that prioritize engagement can potentially (by design or inadvertently) boost sensationalist content or incorrect information.

3. User Fatigue: Users may experience fatigue or disillusionment when they become aware of the potential negative effects of algorithms. Users who feel that their experiences are being engineered may lose trust in the platforms, and they may stop using them.

1. Prioritize Quality Over Quantity: Create meaningful, engaging, and relevant posts.

2. Engage Authentically: Engage with one’s audience in genuine ways such as through storytelling, user-generated content, and responsive interactions.

3. Embrace Video Content: Use videos as platforms are increasingly prioritizing that content.

4. Stay Informed: Marketers should be on the lookout for changes and be responsive to them.

5. Leverage Data Analytics: Informed by metrics, marketers can adjust their strategies when needed.

6. Experiment and Adapt: Platforms are continuously changing. Users’ tastes may change as well. Marketers should experiment with different content types, posting schedules, and engagement tactics to discover what works best for their audience.

1. Transparency: Users deserve to understand how their data is used and how content is prioritized. Increased transparency can foster trust between users and platforms. Is the social media platform transparent about how its algorithm works.

2. Algorithmic Bias: Algorithms are not immune to bias as they often reflect the prejudices in the data they analyze. Is the social media platform taking steps to remove bias wherever possible?

3. Content Moderation: What role, if any, should platforms play in moderating content?

4. User Well-Being: Is the platform primarily focused on providing a great user experience? Or is it about doing anything and everything possible to generate time on the platform and obtain a presumed corresponding increase in revenue?

1. Increased Use of AI and ML: AI and ML will continue to play a role in refining algorithms. As the technologies advance, algorithms will become even more adept at understanding user preferences and predicting behavior.

2. Greater Focus on User Control: Users are becoming more aware of their data and how it’s used. Platforms may offer control to users, allowing users to customize their feeds and manage their engagement preferences.

3. Ethical Algorithm Design: Ethical frameworks that prioritize user well-being, transparency, and accountability may gain prominence in the future.

4. Integration of AR and VR: Social media platforms may incorporate augmented reality (AR) and virtual reality (VR) elements into their algorithms in the future. If that happens, the result will be immersive user experiences that transcend traditional content consumption.

5. Community-Centric Algorithms: Algorithms in the future may prioritize community engagement and collective interests.

• When content is published online, relevance and engagement have a limited lifespan. Engagement is typically not distributed as a normal bell curve. Rather, it’s generally a unimodal distribution-based, positively skewed curve.
• Here’s a description of the prototypical distribution of data (engagement): On average, most posts receive half of their total engagement relatively soon, with the remainder spread out over a comparatively long(er) period.
• For those reasons, an advantageous respective objective metric for posts on social media platforms is half-life. It’s the time it takes for a post to receive half of its total engagement (such as likes, shares, and comments).
• Built on a large dataset from multiple sources, Graffius’ research reveals the average lifespan (half-life) for posts on different social media platforms.
• Note: Findings from others — including anecdotal experience from select posts or otherwise the experience of one person, one organization, or a limited dataset — may vary from the average half-life data in Graffius’ research.
