If you want to create good educational website you need to write good content for it for example about how to write a literary analysis essay or about research paper and students after reading it will buy your works for cheap and fast. So, tell a little bit more about creating your website:
Using a website builder site will save you from typing in HTML commands into a text editor. You will simply click around on things and buttons, type in some text, upload some images, and finally save your web pages to magically appear on the Internet. Site builders are not free because they need to pay for hosting and domain name registrations.
Website builders cannot create just about any website. They are usually restricted to a set of themes and layouts. You simply modify the details but you usually gain no control over the actual HTML code of the site you're building. This means that making small adjustments to your site's layout (just in case you are a perfectionist) may not always be a possibility.
