Hello guys i started off or still i am rather a web developer , i see many of my rivals get into web hosting as well.
Ive dabbled a bit into it and from my point of view it seems like for say a web development company besides the extra monthly income , there can be quite a few benefits to doing this.
One is back links and using the sites under your hosting server to further the back link profile , im not even entirely sure if this is within google's guidelines.

However i would like to ask is it profitable , what are the pitfalls that newcomers like me get caught on ? and also as a hosting service how is easy and is it "legal" to use your client sites to further your own seo .

I know those are many question feel fee to answer o one aspect if you wish to share you knowledge i would greatly appreciate it .

Regards
