Brand Pages UX

Could anyone, tell me what is the main purpose of having brand pages?

I work for an online retails and we carry a lot of big brands. Having those brand pages which can introduce our customers to those unfamiliar brands if they want to know more, also building the trust elements and SEO purpose for driving more organic traffic from Google.

As my next project, which is re-design and re-structure the template for all the brand pages. Is there anything else I should know or consider before I design?

Hi there,
Are you talking about product landing pages? Could you link to an example so that we can understand what you mean?
