Payment plans: Check out very carefully the payment plans of the web hosting provider. A monthly payment plan is always good even if it costs you a few dollars more. You always have the choice to change providers at any time you want. Most web hosts now provide a 30 day money back guarantee period.
Is the website you are hosting a private one? Perhaps, it is a family portal that is meant only for your family members, relatives and friends. Or, are they websites that you will promote to the general public to get as much visitors as possible? In that case, your traffic volume will be quite high each month.
As an online business, your domain name is your storefront; make sure it belongs to you. If you register your domain with any business web hosting provider you are leasing it from them. Some providers maintain more info rights to the name and if you ever want to switch providers, they keep the name. Read the fine print before you sign-up with any outfit. You can register your domain name independently before signing on with a web host. Or better yet find a business web hosting provider that lets you keep or transfer the Hostinger domain name.
You might not understand each of these, but as you get more experienced, having a full array of tools to use will make it much easier to manage your site.
You also want to see how quickly the hosting provider responds to your question. Don't get too excited however if they come back almost immediately. Pre-sales are normally much quicker off the mark than technical support! But it does give an indication.
Last but not the least, compare the prices of the best webspace provider and choose the one which is serving you best and is economic for your pocket.
