Hey web pros!
I noticed that many hosting providers offer unlimited domains with hosting packages.
If I host a bunch of sites this way, is there any downside? I'm thinking it may affect SEO.
It's usually one main domain and all the others are "add-ons" which are set-up like subdomains.
addon1.com is also addon1.PrimarySite.com
addon2.com is also addon2.PrimarySite.com
So any thoughts or knowledge on this?
