The case for staying together
Shared terminology, related questions, and one offer often belong under one domain. Visitors can move between the material without learning a new brand, and you have fewer publishing systems to maintain.
The case for separating
A consumer tool and a professional training program might eventually need different experiences. The decision should follow the audience and product, rather than a belief that more domains automatically create authority.
A practical decision rule
Describe the new site's job in one sentence. If that sentence also describes an existing page, improve the existing page first. If it describes a different product, audience, or editorial responsibility, a separate site may be worth testing.
How we are starting
Fabrique begins with one main domain and a small set of connected question pages. The second brand domain can point to the same destination. That gives us a clear starting point for learning what readers actually find useful.
