Welcome to the Q&A Forum

Hi, I know this is an old thread but I have a similar issue. The company I'm currently working with used to have 30+ subdomains all going to different versions of the same website, many with duplicate content. This was creating 30+ different google analytics accounts to look through and all sharing the same ink juice. Now I have come on board, I have rebuilt the website so that it is one main website with franchisee pages like www.mainsite.com/uk/franchisee-location Now what should be the best option for the 30+ subdomains that are left? At the moment they are all pointing to their respective page on the new website but I have a developer in the team that is adamant that Google is going to penalise us for having the 30+ subdomains pointing back to urls on the main.com website. I'm not convinced as I think this is a much cleaner way and a better user experience. My question really is, what is the best action to take with the franchisee subdomains that are out there still in the Google index? Should I keep redirecting them to their new url (www.mainsite.com/uk/frachisee-location) or should they stay as franchiseelocation.mainsite.com and will Google penalise the domain for this? Many thanks for any advice.
