Need some help in de-indexing some content from google. We have a main domain
Which has listing of E-commerce products. Also, we give this for internal use to companies on their subdomain. Example company1.website.com company2.website.com . . . company100.website.com
Problem is, google is detecting the content of our main site as duplicate. Can you guide me how to prevent this? I am ok to block crawling of microsites as they are for internal use only.
