How to choose a web host should not be a hard task, it all depends on what kind of website you're going to host.
When I first begun to build websites I was relying more on the price of the hosting than its quality, that's why I decided to write these 3 tips to help you choose a web hosting that will not let you down.

How to choose a web host - Rule #1 - Liability

Choosing a web host should not be like choosing paper, they are not all alike, so the first tip here is to choose a web host which is responsible and haven't had too many complaints from old customers, it more often happens when the websites get offline because of a spike on its traffic, when it happens your website go offline and you need to contact your hosting company to make them fix it for you, but what if it is an affiliate website and every minute your website is offline you're losing customers?
Which lead us to the next tip.

How to choose a web host - Rule #2 - Support

You want to know how good it is their client support, how long do they generally take to reply to a question from you, if you they have an online chat service which can help you sane your doubts right always, because we all know how frustrating it is to have an issue and having to wait until the next day in order to solve this!

There are many web hosting providers that also provides you with a Toll Free phone number which can be really handful when they don't reply your messages and/or the chat is full and you are like the #20 on the line to talk to their support team.

How to choose a web host - Rule #3 - Additional's

There are 3 things that I find paramount when choosing a web hosting additional's:

1. Bandwidth: If your web hosting offers a low amount of bandwidth, prepare to get in trouble, once you have an increase of your traffic and let's say your bandwidth is only 2000 Mb, what is going to happen is that your website will get offline, and you won't know it, because they don't tell you your website is offline due to Exceeded Bandwidth. And you'll have to pay more for additional bandwidth. So keep it in mind before you choose a web hosting that is "cheap", in the end, you'll have to pay more anyway.
2. Databases: Unlimited Databases, if they don't offer it, I just skip.
3. Disk Space: Unlimited as well, is not like you're going to use all the space they offer, but you never know, I'd rather choosing a web hosting with loads of disk space than choosing one that is limited.
