🧩 Methodology & Formulas

Content Types Performance

Shows engagement distribution by content type (Image, Video, Text, Link). Segment size reflects relative effectiveness on the platform.

Formula: (Relative activity for an average post of that format) / (Sum of relative activity across all formats) × 100%

Classification: posts are grouped by primary media. Videos include Reels/Shorts and regular feed videos; Text is based on presence of text; Links include external links or page mentions.

Use: quickly identify preferred formats, optimize content mix, and reveal general platform patterns.

Text Length Performance

Displays how text length affects engagement. Categories: Short (0–160 chars), Medium (160–1000), Long (1000+).

Formula: (Relative activity for an average post of that length) / (Sum of relative activity across all lengths) × 100%

Character counting: includes all visible caption text, including hashtags, mentions, and links. Emojis count as one character.

Knowing effective lengths helps improve engagement and reach. On Instagram, medium captions work well; on Twitter, shorter posts perform better.
