Can sub-domains get good rankings?
Next week I'm moving my health site domain/niche over to WA, and that is such a broad Niche, so I was going to add different health niches to it under separate pages, like Diabetes, Cancer, OCD, restless leg syndrome, acid reflux....well you get the picture...lol..Would I have to buy a different domain for EACH health Niche? That could get expensive if I do! My main domain name is Everything Health Online, so I want to deal with everything health..planning on going big with it! Could I just add a sub-domain to the main Niche, and still be ranked good in the search engines? Would the https cover the sub-domains as well as the main one? Any advice would be appreciated! Thank you! :)
