Algorithms tailor content to each user, showing posts that match interests and past behavior. They amplify content with high engagement—likes, comments, shares—pushing viral posts. This means users often see echo chambers of similar ideas, limiting diverse viewpoints. Timely or sensational content may be boosted over informative ones. Paid ads are also prioritized based on targeting.

Algorithms shape user experiences, making feeds feel relevant—but also addictive or polarizing. They influence everything from shopping habits to political opinions. While they enhance personalization, the downside is a lack of transparency and control over what content gets promoted or suppressed.
