You need to consider before buying a web hosting important points
In order to rank in google you need to choose Fast and Secured web hosting
Because of choosing a:
Fast Web hosting: Will help you to rank faster!

So fast and secured.
How to choose a fast web hosting?
Now most of web hosting companies use: Nginx as a web server or Litespeed which is faster than nginx!
Using Lsapi from Cloudlinux or Litespeed as a php module will help boost your php scripts and fixes issues with it!
I'm using Subwayhost as it has all of these options and i can use it for life plus you can consider their prices is very fair and will help your business to gain thousands of dollars.
