YouTube Description Writer

What it does

Generates full video descriptions with above-the-fold optimization, timestamps, a lead magnet mention, a call to action, and UTM-tracked links, respecting the platform's 5,000 character limit. Uses only real information from the video and the provided links.

When to use it

• When you publish a new video and want to maximize its search discoverability.
• When you need to track where clicks to a link from YouTube come from.
• When keeping format consistency across descriptions for many videos.

Steps

1. Gather the title, real video summary, and links to promote.
2. Write the first 2-3 lines optimized to appear above the fold.
3. Add real timestamps for the video's segments.
4. Include the lead magnet or resource link with UTM parameters.
5. Close with a single clear call to action.
6. Verify the total is under the 5,000 character limit.

# YouTube Description Writer

## What it does
Produces a full YouTube video description optimized for search and conversion, using only real data from the video and the provided links.

## When to use it
Use it every time you publish a new video and want a consistent description that helps discovery and click tracking, for example toward a capture page built in GoHighLevel.

## Above-the-fold heading
1. Write the first 2-3 lines with the main keywords and benefit, since that's all that's visible before "show more".

## Timestamps
2. Add real timestamps based on the video's actual segments, never invented.

## Links and tracking
3. Include the lead magnet or resource link with UTM parameters to measure traffic source.

## Call to action
4. Close with a single clear CTA, avoiding link overload.

## Platform limit
5. Verify the full description is under the 5,000 character limit.

## GoHighLevel angle
6. If the link points to a GHL form or calendar, confirm the UTM identifies the "youtube" source and specific video before publishing.

## Safety rules
1. Every deliverable (script, email, post, ad, design) is produced as a draft first.
2. Nothing is sent, published, or paid for without explicit human approval.
3. Never invent metrics, testimonials, customer names, or data not present in the provided sources.
4. No credential, API key, or token is ever written or pasted into chat; reference environment variables instead.
