Postprism schedules your YouTube content at the hours when your subscribers are most active and helps you write descriptions and tags optimized for YouTube search — the second-largest search engine in the world.

Postprism adapts your content to YouTube's format, timing, and audience expectations automatically.
AI-optimized YouTube descriptions and titles
Postprism generates YouTube titles with primary keywords in the first 60 characters and writes descriptions that frontload critical information in the first 150 characters — the visible fold before "Show more."
Scheduled video publishing
Set a video to publish automatically at any date and time. Postprism uses the YouTube Data API to schedule your video's public release, so it goes live precisely when your subscribers are most active.
Tag and keyword tracking
The Postprism editor counts tag characters in real time against YouTube's 500-character limit and suggests keyword placement in titles and descriptions based on your content.
Cross-platform promotion scheduling
When a YouTube video publishes, automatically schedule promotional posts to LinkedIn, Twitter/X, Instagram, and Facebook — each with platform-adapted copy written by Postprism's AI.
Video title
100 charactersYouTube displays approximately 60–70 characters in search results and suggested video thumbnails. Place your primary keyword in the first 60 characters.
Video description
5,000 charactersOnly the first 150–200 characters appear above the "Show more" fold. Place the most important information — links, keywords, summary — in the opening paragraph.
Tags
500 characters total across all tagsTags are a secondary ranking signal. Focus on 5–10 highly relevant tags rather than exhausting the limit with loosely related terms.
Chapter markers
No character limitTimestamps in descriptions automatically create chapters in the video player. Chapters improve viewer navigation and increase watch time, a critical YouTube ranking signal.
Thursday and Friday, 12:00–4:00 PM — viewers browse YouTube in anticipation of the weekend
Saturday, 9:00–11:00 AM — weekend morning viewing peaks before afternoon activities
Sunday, 5:00–7:00 PM — evening viewing before the Monday mindset sets in
Consistency matters more than optimal timing on YouTube. Subscribers who watch your content regularly drive YouTube's notification and suggested video systems.
YouTube's algorithm optimizes for watch time and session time above all other signals. Videos that retain viewers through to the end — or prompt them to watch another video — receive the strongest distribution in search and suggested videos.
Click-through rate (CTR) from thumbnails and titles is the first gate. YouTube tests new videos against a subscriber subset. High CTR signals relevance and triggers wider distribution.
YouTube search is the second-largest search engine after Google and is powered by its own keyword index. Video titles, descriptions, transcripts (auto-generated or uploaded), and tags are all indexed.
YouTube surfaces videos in suggested feeds long after publish date — sometimes months or years later — if they continue to be watched. Unlike social platforms, YouTube content has a long tail of discoverability.
Community tab posts, comments replies, and Shorts help maintain channel activity signals between video uploads, which can improve the performance of new video releases.
Long-form video
Videos over 10 minutes are eligible for mid-roll ads and have more room to accumulate watch time — a primary ranking signal. Tutorials, reviews, and deep-dive content perform best.
YouTube Shorts
Vertical video under 60 seconds with a dedicated Shorts feed and separate algorithm. Shorts can cross-promote long-form content and grow subscribers from new audiences.
YouTube Live
Live streams generate real-time notifications and can run for hours. Live replays are indexed on the channel and continue generating views and watch time after the stream ends.
YouTube Premiere
A scheduled live event for a pre-recorded video. Premieres build anticipation and generate live chat engagement during the debut, which signals strong launch performance to the algorithm.
Community post
Text, image, and poll posts visible to subscribers in the Community tab and feed. A valuable way to maintain audience engagement between video uploads.
