I was recently tasked with re-designing the header for 3 websites that all belong to one parent company. Each website is a unique learning program that the parent company offers. While all programs are part of an overall curriculum, each program is marketed and generally presented as a stand alone product.
My current challenge is designing a header or a top bar above each website's main header & navigation that offers quick links to each of these programs. My solution at the moment is exactly this, a universal header that displays a link to each website and highlights the website the user is currently on.
I am having trouble finding the resources and information on best practices or standards for approaching parent/child websites like this. I have found some websites that are already doing this but would like to dig deeper into the subject and possibly understand the psychology behind this a bit more.
My question: Are there any resources or known best practices for multi-brand website headers? Is there a specific name for this kind of header that would help me find more information?
Note: The examples below were found in this article but I am wondering if there is any information specific to the design and usability of a header like this.
Thanks in advance
