A similar question was already asked here, but I have a more specific concern. I have been tasked with creating a single website for a parent company and a subsidary. The parent company is just a holding company, and this part of the site should only feature investor focused information. The consumer side is the outward facing public site and should be the primary focus of the site. Both companies have similar names, so for anyone unfamiliar with the corporate structure of the organization, it can be a bit confusing about the differences between the 2 and the different functions they serve (I know I was in the beginning).
The CEO of the company has asked for the investor relations portion of the site to be more prominently featured, and has requested a type of "landing page" upon entering the site where users can select either the "consumer side" or "investor side" (with each button option featuring the separate name and logo of each company - which are similar). Again, this is all under a single domain (which features the name of the consumer company).
I have tried to convince the person in charge this is a bad idea. Making a visitor figure out which way they need to go to get the information they desire seems like it will be a turnoff, not to mention confusuing when unfamiliar with terms like "holding company" and "subsidary". I have suggested if they want the parent company/investor relations section to be more prominent, they should have separate website and just make sure it is easy to navigate between the 2 sites. However, he insists we do this under a single website/domain to make maintenance on the backend easier.
Any suggestions about best practices or concrete examples on why the landing page would be a bad idea? I am banging my head against a wall on this trying to convince the boss of this...
