Make Product Viral
Use this skill to improve a product surface so people can understand it quickly,
trust it before paying, remember it after leaving, and share it without needing
to decode the whole page first.

Core Lens
A viral product is not just a product with social sharing. It has a simple
promise, visible product proof, low cognitive load, a clear buying path, and a
memorable reason to talk about it.
Optimize in this order:
- Can people understand it in seconds?
- Can they see or try the product before reading a long explanation?
- Is the desired outcome concrete, emotional, and memorable?
- Is there one obvious next action?
- Is trust visible before the user is asked to pay?
- Is the page easy to share, including its final impression and social preview?
Resource Routing
Load only the files needed for the task:
| Need |
Read |
| Full audit sequence for a product, landing page, pricing page, launch page, free tool, app-store surface, or OG image |
workflows/audit-product-surface.md |
| Attribution, caveats, and ethical guardrails |
references/source-and-caveats.md |
Fast Workflow
- Write the product in one clear sentence before making lower-level changes.
- Check whether the first viewport can sell alone: what it is, who it is for,
the result, why to believe it, and what happens on click.
- Move visible product proof before long explanatory copy.
- Remove mixed-message sections so each screen or section carries one idea.
- Make the primary CTA specific to the next action.
- Check trust, pricing clarity, and paywall fit before recommending launch
traffic.
- Review the social preview and final impression as shareable artifacts.
Output Format
When using this skill, respond with:
- Viral diagnosis: the main reason this is or is not likely to spread.
- Highest-leverage fixes: 3 to 7 changes, ordered by impact.
- Hero rewrite: headline, subhead, CTA, and proof or demo suggestion.
- Shareability pass: OG image, footer or final impression, and one-line
description.
- Pricing or paywall note: only if relevant.
- Validation plan: what to check before launch.
Keep recommendations concrete. Prefer replacement copy, section order, product
proof, pricing structure, and specific UI/content changes over abstract advice.
