Direct answer
A conversion-led WordPress brief should define audience, offer, buyer doubts, page goals, proof assets, content responsibilities, technical requirements, SEO basics, analytics needs, launch risks and post-launch care. The brief should describe the decision the website must help buyers make, not only the pages required.
Why it matters
This answer connects website design to the buyer decision the page must support. A useful website is not only a layout; it is a path through clarity, proof, trust, calls to action, tracking, launch risk and maintainability.
What to check
- What must the visitor understand, believe and do next?
- What proof, copy, page structure and tracking support that decision?
- What will make the site easier or harder to maintain after launch?
Common mistake
Treating a website as a design surface before the buyer path, content, proof and post-launch responsibility are clear.
Caveats
Low caveat risk: suitable for publication from the available source pack, but still avoid pricing, guarantees, unsupported service promises or claims not visible in the linked public ecosystem.
