To have one reliable source for top content in a particular niche.
Instead of creating original content by in-house writers, have many external excellent creators do it. It might have already been published on the author’s website, another platform, or directly submitted. In any case, a dedicated editor for the particular vertical has (after finding it and contacting the creator) been working with the author for it to be published in the specific vertical’s online publication. The article itself and not a link to it is published. Only chose the top content for each niche.
