Why use SEO?

What is reason that website owners should perform basic SEO techniques on their website? The reason is that  most websites owners is to have visitors come and see their website and either read the information on that website or to buy a product / service from that  website.
So how can these visitors get to the website? Well they may type the url directly into their browser, keeping them straight to the website. They may have followed a link from another website or they may have helped through a search engine like Google/Yahoo/Bing.

When we use search engines, we type in related keywords that describe the website or something  we are looking for. So using SEO techniques will help your website get found for the actual keywords. This will then lead to people who have never heard of your website before, If your website has been designed badly, then there is a possibility that no new visitors will ever see your website through the search engines.
