Hosting is a dull topic but really important. It can be troublesome to change hosts so many people stay with the first one they find. That could have been because they were offered a cheap or free domain name.
Hosting is important because it dictates how quickly people can view your website. You know how frustrating a slow website is, if you can you go elsewhere after a few seconds or even less. Google know that too and penalise slow sites.
Support isn’t something you want to use often but when you need it you want quality help. This variable can mean the difference between your site having problems for days or a quick fix.
Our experience has seen us use many hosts and we’ve seen the difference and been on the wrong end of the bad guys. We’ve got a good balance of cost and performance with our two hosts and to underline that the WordPress creators themselves only endorse four hosts and one of them is the one we use and recommend.
