What is Series Health?
This system provides a composite score for each manga, displayed as a UIkit progress bar with an expandable dropdown breakdown. The score combines six key aspects: daily views, growth momentum, reader retention (drop-off), engagement, freshness, and playlist mentions. The goal is to help authors, editors, and admins quickly assess the condition of a series and make better content and publishing decisions.
How does it work?
- Daily View Strength: compares today’s views against the min–max range of the series’ own history, ensuring consistent scoring across both small and large titles.
- Growth Momentum: uses
Day/WeekandDay/Monthratios to measure acceleration or slowdown. Ratios are normalized to avoid bias. - Reader Retention (Drop-off): reuses the hazard-based model from the Drop-off module (with Bayesian smoothing and recency decay) to produce a reliable retention score — the fewer readers dropping, the higher the score.
- Engagement: combines followers, Power Stones, and ratings. Signals are normalized and aggregated into a single engagement score.
- Freshness: based on
init_manga_update_time(last update), with a time-decay function that favors recently updated series. - Playlist Mentions: counts how many user playlists include the manga. Stored in a fast meta-based counter (
_playlist_mention_count) with automatic bump/rebuild. - Default Weights: Views 35% · Momentum 20% · Retention 20% · Engagement 15% · Freshness 7% · Playlist 3%.
- Performance: efficient calculation with 10-minute caching per series, no cron jobs required.
Interface & Visibility
- Frontend: progress bar (UIkit) + dropdown details (click to reveal today’s numbers, momentum ratios, last update time, playlist mentions, etc.).
- Role-based access: visible only to Administrators, Editors, and the manga’s Author.
- Admin Metabox: new Series Health metabox in the Manga edit screen, read-only and auto-calculated.
Benefits for your site

- Boost retention: identify problem points and optimize flow to keep readers engaged longer.
- Optimize release strategy: balance freshness and momentum to choose the best time for new chapters.
- Lightweight operations: no heavy batch jobs; caching and meta counters ensure performance even at scale.
Enable/Disable & Control
- Display option: Series Health can be enabled/disabled in Init Manga → Settings → Display Options. Only shown when enabled and the viewer has sufficient role permissions.
- Extensible: scoring weights can be adjusted, and additional factors can be added depending on site strategy.
