FAQPage Schema
How do I audit a landing page to ensure my copywriting leads with user problems?

To audit landing page copywriting, use a critic mode to evaluate the homepage hero against project source material, generating a prioritized list of improvements that align messaging with audience needs. This ensures the human story leads the product mechanism.

What is dual-perspective analysis for product positioning and when do I need it?

Dual-perspective analysis for product positioning provides bull and bear advocacy viewpoints on campaigns and launch strategies. You need this strategic analysis when validating messaging direction to ensure your positioning withstands critical scrutiny before going to market.

How do I map content architecture to eliminate page duplication on my website?

To map content architecture and eliminate page duplication, audit multi-page sites to define specific page-jobs and audience-routing paths. This process clarifies the unique responsibility of each page, preventing overlapping messaging and improving user navigation.

Can I produce production-ready landing page copy without providing a project context brief?

No, you cannot effectively produce production-ready copy without a project context brief, style guides, and source material. The Skill requires these inputs to ensure all communication is grounded in the project's unique mandate and human-centric stakes.

What's the best way to align marketing copy with a mission-driven project's core mandate?

The best way to align marketing copy with a mission-driven project is to feed project context briefs and style guides into an architect mode. This grounds the content architecture and copywriting in the specific human stakes of the project rather than institutional messaging.

Why does my SaaS homepage hero feel disconnected from my target audience?

Your SaaS homepage hero likely feels disconnected because the copywriting leads with product infrastructure rather than the user's problem. Critique the hero section against source material to shift the focus back to human-centric communication.
