A thousand doors, one rule

A video with 144,000 views explains how to take over an industry with a thousand small sites: split plumbing into sub-trades, multiply by every suburb, one exact-match domain each, flat HTML, a tracked number answered by an AI agent, about eleven dollars a site. The safety argument is one line: "Interlink nothing so there is no network to catch. So, this is not a PBN."

• The technical half is right, and we agree with it: static HTML is cheap, fast and far safer than a plugin stack.
• Being explicit about method, cost and tooling is more than most of this genre offers.

• The rule is not about links. Google defines doorway abuse as pages "created to rank for specific, similar search queries", with the example "Having multiple domain names or pages targeted at specific regions or cities that funnel users to one page."
• Scaled content abuse lists "Using generative AI tools… to generate many pages without adding value for users" and "Creating multiple sites with the intent of hiding the scaled nature of the content." Not interlinking does not leave either definition; it reads closer to the second. Sites that violate "may rank lower in results or not appear in results at all", detected by automated systems and human review.
