From the perspective of building trust in the brand (or, as I like to call it, a technical sub-brand), wouldn’t it be better, in your opinion, to create a landing page for each technical domain targeting specific keywords - ideally those with a chance to rank on the first page of Google without heavy link building?
This way, a client visiting the sub-brand’s site wouldn’t be redirected to the main site but would be “served” directly by that brand.
It seems quite sensible to me.
I did something similar for the German market once and acquired a client who ended up spending $200,000 annually.
Please share your thoughts.
