One of the most critical component of your website is your web-host. Imagine if your website is down for an hour, how much traffic will it dissapear? How much revenue lost? Here you can learn how to choose a good hosting with good price:

• check for their infrastructure. With poor infrastructure, they can offer low prices. Consequently, their service is low and quality of services being delivered. Highly skilled customer-service costs money. You can send email to them, and see how they answer. You usually will know if they are good or not.
• Check for reliability and speed of access. They should guarantee its uptime (the time when it is functional). Look for a minimum uptime of 99%. The host should provide some sort of refund if it falls below that number, although it is hard to claim them.
• Check for restriction, like restrictions on their users, number of domains, bandwidth limit, maximum file size limit, FTP access, email account, and database limit. You must know your requirement before signing up for a hosting package.
• Check for contract. Read the terms of service carefully before you sign-up with the webhost. You do not want them to charge you more when your website is getting popular. See if there are any hidden cost. Ask them if they will charge excess bandwidth and space, and cost of upgrading an account.
• Check if they are reseller of other hosting companies. The disadvantage of using a reseller is the possibility that you are dealing with people who don't know much about the business they are selling and could not give fast and good support. However, this also depends on both the reseller and the underlying hosting company. So you need to check again, ask them questions about their hosting.
