What belongs on an author website homepage
The homepage answers three visitor questions in order: who is this author, what should I read first, and what do I do next. Lead with the current book and one action — buy or sample — supported by a short credibility line and a subscriber offer for visitors not ready to purchase. Everything else (full catalog, about page, contact) belongs one click away, not on the first screen.
The commonest failure is decoration without a decision: a beautiful page where no element is obviously the next step. Pick the one action that matters this quarter and make it unmissable.
