Siteground is a newer hosting solution I have been using but am super happy with it. They get you hooked with a low price for the first year then you’re a bit locked in on the second year to move somewhere else. But still reasonable at 35 bucks a month – if you are a power user like me.
Why? Because it allows unlimited add-on domains and it also manages your wordpress (something other unlimited add-on hosting solution providers offer). So I use this for sites where it may not be my “main money site” (that may be more suitable on WPengine or on a dedicated Siteground plan) – but great for middle-level sites where I am looking for good and reliable but not unlimited power – if that makes sense?
