One article about generative video costs is a page. A costs article, a measurement methodology, a glossary of the terms it uses, a published pipeline and a calculator that shows the arithmetic is a position. Systems that decide who to cite are increasingly able to tell the difference.
What builds it is coverage of a subject’s real surface: the buying question, the method, the failure modes, the definitions and the regulation. What does not is the same claim restated across fifteen pages at different keyword densities.
The internal linking matters because it is how the coverage is legible. A cluster that does not link to itself is a set of pages that happen to share a topic.
How do you build topical authority?
Cover the real surface of a subject: the buying question, the method, the failure modes, the definitions, the regulation, and the tools. Then link them so the coverage is visible.
Does publishing more pages help?
Only if they say different things. Restating one claim across fifteen pages is volume, and it is increasingly easy for a system to recognise as such.
