Not every webmaster in the internet is backed by a huge fund.
Most are individuals or even small business owners who just want to have a web presence.
Therefore, a dedicate server would be a huge investment and may be a burden.
So, they turn to shared hosting.
That is why it is regarded as the most popular type of hosting in the web hosting industry nowadays.
However, popularity does not mean incredible performance because shared hosting is also popular for its limitation preventing your website from achieving bigger goals.
The first problem that users will get with it is the lack of reliability.
As it is hosted in a shared server condition, numerous websites are being hosted together.
This decreases the usage of the server resources for the webmaster as they have to share it with whoever that is in the same server.
There is also the fear of your website going down because there might be many buggy scripts running in your server.
Some provider even oversells their resources creating problems for their clients.
Then, there is the billing system that involves extra cost when you want to upgrade.
This is a trap that many new webmaster fall into.
The packages may seem to be cheap in the beginning but as you reach the maximum of your resources, an upgrade is inevitable and this is where you will feel the pain.
Therefore, read the company's terms of service clearly before you make any decision.
There are countless shared hosting providers out there.
Some lousy ones will limit the amount of add-on domains that you can add.
This is due to their lousy hosting feature which lacks experience and reputation.
So, always go for more reputable companies like BlueHost or Lunarpages for better features.
Last but not least, you can imagine that you will only be getting limited technical support from the provider.
Logically, they will definitely tend to customers who are paying more.
In this case, are the dedicated server users.
So, shared hosting users will be second in line.
So, don't be surprised if you have to wait a little longer on the line when you phone them for support.
