Everything the other 5 pillars teach (automation, SEO, SEM, AEO, GEO) needs somewhere to live: the book's or author's website. This pillar is about that architecture — not pretty design, but the structure that determines whether a specific reader finds you or not.
The first decision: a hub or a site per book
When a catalog is broad and covers very different topics, there are two possible paths, and they're not interchangeable:
A separate site (or subdomain) per book/niche: each with its own content hierarchy, 100% focused on its topic. Better when the topics have nothing in common and one book's reader has no reason to care about another.
A central hub with clusters per niche: a single brand (the author's or the publisher's) with sections split by topic. Better when you want to build one brand authority that benefits from all the books together, even if the topics differ.
There's no universally correct answer — it depends on whether the value lives in the individual topic or in the brand connecting them all.
Design for each book's specific reader, not "readers in general"
A common mistake is building one generic "author" site and expecting it to serve every book in the catalog equally. Each book has a reader with a different search intent — the site (or the hub's section) needs to reflect the language, problem, and tone that specific reader recognizes, not an averaged-out version of every reader in the catalog.
Checklist before launching a new site per book/niche
Have you already identified that specific book's micro-niche and long-tail keywords? (See the SEO pillar.)
Does the design and copy speak directly to that topic's reader, or is it generic?
Is the pillar → clusters → articles structure clear for that niche, or is it being improvised on the fly?
Does the site link back to the central hub (if one exists), so brand authority accumulates?
A complete topical map traced from day one (pillar → clusters → long tail) allows systematic coverage of a niche, instead of discovering later which parts of the topic went uncovered while competitors filled them.
