To make an e-business first you need to know the type of business you're making. You need to make a plan for your business like for example what you're going to need for your business in order to run it. After you have your business you're going to need a domain name (URL) for your website. After you have your URL you actually need a website so you can either design your own website, get a professional to do it for you or you can go to a website where you can just pick a template and do it yourself. Now that you have a website and URL you will need a web host which you can get from multiple websites for example www.justhost.com, www.godaddy.com, ect.
Now that you have a website if you're selling something you will need an online shopping cart or a source of payment, you can choose something like paypal or let people use credit cards. If youre going to be using money you should provide web site security, when you don't have a "insurance" on your site, not a lot of people will want to buy there because they won't know if its secure or not therefore they wont trust it. You should also have a good costumer support, have contact information like an e-mail address, or mailing box or a phone number where they can contact you or somebody that will help them if they have an issue.
You will also need to submit your URL to different search engines so that people may find you if they're looking in a place like google, bing, yahoo, ect. You should also have Meta-tags, what these are is key-words, once you have your URL it will search for keywords so when someone puts a word in a search engine that is one of your key words then it will pop up and people will be able to find your website easier.
