Understanding Instagram Reels Basics
Instagram Reels is a feature that brought the short-form video format popularized by TikTok to the Instagram platform. It allows users to create and share vertical videos up to 90 seconds long. As of 2024, more than 30% of total time spent on Instagram is dedicated to watching Reels.
The 3 Key Elements of the Algorithm
Here are the criteria used to determine what appears on the 'Explore' tab:
1. Watch Time (Completion Rate)
The most critical metric is whether a user watches the video to the end. If users watch without dropping off within the first 3 seconds, or re-watch the video, the algorithm judges it as 'high quality' and exposes it to more people.
2. Engagement
Interactions such as likes, comments, shares, and saves are powerful signals. Specifically, 'Saves' and 'Shares' are gaining more weight, as they indicate the content is informative or useful.
3. Audio and Trend Relevance
Using Trending Audio alone significantly increases your chances of exposure. Instagram has an audio-based search and recommendation system, making it advantageous to use popular tracks.
2025 Algorithm Changes
The trend is shifting from simple entertainment to emphasizing 'Originality'. Content with watermarks from other platforms (like TikTok) is restricted, while unique content filmed and edited directly is favored.
