YouTube Channel Optimizer

Audit the parts of a YouTube channel page against what actually converts a one-time video-viewer into a subscriber in 2026, then rewrite each part that needs it. A viewer clicks through from one video to the channel page in a moment of interest. That moment decides whether they subscribe or leave. This skill fixes the page so the answer is subscribe.

When to use

• User pastes their channel URL or @handle and asks for an audit
• "Rewrite my channel About", "fix my banner", "set my trailer"
• A channel with real videos but a default or empty channel page
• Any of: "optimize my YouTube channel", "channel audit", "what trailer should I set"

Not for writing a single video's title (use yt-title-optimizer), the video description (use yt-description-writer), or the thumbnail overlay (use yt-thumbnail-brief).

Input

• Channel URL / @handle (or a screenshot of the channel home tab, signed out)
• Goal: more subscribers / more views / authority / sales - the trailer, About CTA, and section order change by goal
• Optional: their best-performing videos, to pick a trailer and featured video
• Note whether the channel already has 3+ playlists to lay out

Output

1. Scorecard (parts, pass / needs-work / fail)
2. Priority fixes ranked by impact (trailer, banner, and About first)
3. Before -> After rewrites for each failing part
4. Trailer + featured-video picks with the reason for each
5. Section-order recommendation matched to the goal

Steps

1. Intake. Collect the channel state + goal. View the channel home tab both signed out (non-subscriber sees the trailer) and as a subscriber (sees the featured video). The two audiences see different things; audit both.
2. Score the parts against the scorecard below.
3. Fix the channel name + @handle. Name is a real name or brand plus a searchable topic ("Sam Rivera - AI Tools"). The @handle is short, memorable, no numbers if avoidable. The name field is searchable; set it with intent.
4. Rewrite the About + keywords. First 2 lines carry the value prop (they show in the sidebar preview). Structure: who the channel is for, what they get, how often, one proof. Weave the real search phrases people type into natural sentences; do not keyword-stuff. Add business email and links.
5. Set the channel trailer (non-subscribers). A 30-to-90-second pitch: who you are, what the channel delivers, why subscribe now. This is the single highest- leverage slot for subscriber conversion. Not a random recent upload.
6. Set the featured video (subscribers). Returning subscribers see this instead. Use your best recent video or the one you want watched next, matched to the goal (a launch, a flagship, a series opener).
7. Lay out featured sections + playlists. Group videos into 3+ named playlists by topic or series, then arrange them as sections. Playlists lift session watch time (autoplay into the next video) and tell a new visitor what the channel is about at a glance. Order sections by the goal: lead with the series that converts, not "Uploads" by default.
8. Order the sections. Trailer/featured first, then the strongest playlist, then popular uploads. Bury generic "Recent uploads" below the curated rows.
9. Banner check (2560x1440). Design inside the 1235x338 centered safe area so it reads on mobile and TV where the edges crop. One line of value prop + upload cadence ("New AI builds every Tuesday"), high contrast, not a busy collage. It reinforces the About, it does not repeat it.
10. Profile picture check. Clear face or clean logo, high contrast, recognizable at the small circle size it renders at across watch pages and search.
11. Watermark + links. Set a branded watermark (a subscribe-prompt or logo) that shows on every video for one-click subscribe. Add the goal-matched links (site / newsletter / offer) to the banner link row; one primary link wins.
12. Deliver the before/after diff + the one-visit test: a stranger who clicks through from a single video should, from the trailer + banner + About alone, know what they get by subscribing and want to.

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

• Audit the channel page as both a non-subscriber (trailer) and a subscriber (featured video). They are two different first impressions.
• The banner must be designed inside the 1235x338 safe area centered in the 2560x1440 canvas. Anything outside it is cropped on mobile and TV. Never put the value prop near the edges.
• The trailer is the highest-leverage slot for subscriber conversion. A channel with no trailer leaves that slot empty; always recommend setting one.
• First 2 lines of the About carry the whole value prop (they show in the preview before "more"). Lead with the viewer's benefit, not a mission statement.
• Real search phrases in natural sentences. Never a comma-separated keyword dump.
• One primary link. A wall of links dilutes the click.
• At most one em dash in the About text (about one per 100 words). No "leverage", "fundamentally", "unlock".
