I have a SaaS platform where people can create their own white labeled job boards.
My main product domain is www.myproductdomain.com
When clients sign up they automatically get clientname.myproductdomain.com. They can also choose to use a custom domain by setting up a CNAME.
At the bottom of every white labeled site is a link back to my main site "Powered by My Product Name". Should I consider making these nofollow links?
I have around 1600 clients using the product at the moment.
