A website can be a way to make money but it is worth being cautious and understanding the costs and the work that will need to go into it. You will need to think about the expense of the domain name, hosting and design, if you pay a designer to put it together for you . These could add up and you will need to see whether you can make money really quickly in order to cover these costs so that you can then start making money from the site. You could set up the site for free, using a free domain and hosting, but this does not look very professional and could mean that potential customers will be put off, thinking that you are not very serious about the site.
You will need to think, before you even design the site, about how you are going to make money from it. There are different options available and you will need to think about which will suit you. You could sell things form the site, but only if you have goods or services available to sell or you are prepared to buy items to sell on. This can take an investment of money and you may find better places to sell rather than a website of your own, such as Amazon or ebay. They already have lots of trusted customers and lots of people trust them so selling through there can bring about a lot more income than selling through your own site.
You could try to make money through advertising or affiliate links on the site. This can earn income, but there is a lot of competition these days. This means that you will need to think hard about how you will go about it. It is good to think of some ideas of what you might like to make your site about and then see what other sites there are and whether you can make a site that is significantly different to it or not. Think about what you can do to stand out from the others. It may be wise to try to find a niche that you can slot into which will allow you to get unique visitors who want to get something from your site that they cannot get form anyone else or make your site appealing in some other way by making it the most up to date, prettiest or something like that.
It is also very important to make sure that you promote the site widely. You will need to make sure that a lot of people visit the site so that you have a good chance of making money from it. Without visitors, there will be no opportunity to earn, however you choose to earn money. This promotion can cost a lot of money, although there are free ways to do it. You will need to consider whether you have any money to invest in promoting it and what ways of promoting you think might be the best.
