Built for how YouTube actually ranks videos
Every description follows YouTube's 2026 SEO best practices
Keyword Rich First Line
YouTube truncates at 150 characters. The generator packs your primary keyword and the core value into the opening sentence so it lands above the fold.
Chapters with Timestamps
Chapters start at 00:00 with at least 3 segments, unlocking Key Moments in YouTube and Google search so each section can rank on its own.
Hashtags in the Sweet Spot
3 to 5 hashtags per video (the data backed optimum). First 3 show above the title. Never more than 15, which would make YouTube ignore all of them.

Frequently Asked Questions
Everything you need to know about writing YouTube descriptions
A strong YouTube description has four parts. First, pack the primary keyword and core value into the opening sentence (YouTube truncates the visible description at around 150 characters before "Show more"). Second, write a 200 to 500 word body using the keyword naturally, explaining what viewers will learn or see. Third, include chapters with timestamps starting at 00:00 (minimum 3 chapters unlocks the "Key Moments" search feature so each section can rank independently). Fourth, end with 3 to 5 hashtags (never more than 15 or YouTube ignores all of them). Our generator handles all four automatically.
You can generate descriptions for 8 video types: Tutorial / How To, Review, Vlog, Educational, Gaming, Product or Unboxing, Podcast, and Shorts. Each type is structured differently. Tutorials include step by step chapters. Podcasts include guest links and show notes placeholders. Product descriptions include an affiliate link section. Shorts get a tight 1 to 2 sentence description with hashtags (no chapters, since YouTube Shorts do not support them).

YouTube allows up to 5,000 characters in a description. The SEO sweet spot for long form videos is 200 to 500 words. The first 150 characters matter most because that's all viewers see before tapping "Show more". YouTube's algorithm also prioritizes the first 200 characters for search relevance, but crawls the full 5,000 characters to build topical context for recommendations. For Shorts, keep the description under 250 characters, focused on the primary keyword and 3 to 5 hashtags.
Yes, for every video type except Shorts. YouTube requires chapters to start at 00:00 and needs a minimum of 3 chapters to trigger the "Key Moments" search feature, which can rank individual sections of your video as separate results in Google search. The generator always produces chapters starting at 0:00 with at least 3 segments, formatted correctly for YouTube. Shorts skip chapters because YouTube does not display them on Shorts.
