Search Engine Optimization Tutorial
Do Not Use Images For Content

The image above is an example of the worst possible way to design a site. This is the home page of a website which is composed entirely of images. The text you see on the right side is not text at all. It is actually a part of the picture, and more images are used for navigation.
They have no English sentences on the page- just a lot of pictures of products and perhaps a few bullets and some menus.
This results in the same problem that designing a website entirely in Flash causes. Search engines are text-based, and the site has no text for them to read.
This site will rank at the end of the pack, if it is ranked at all.
