03. Why is SEO necessary?

SEO is necessary to gain maximum visibility and exposure of your website. There will be thousands (quite possibly hundreds of thousands) of websites that are related in some way to your business activity. So, optimising your website for the search engines will help you to appear higher in the search results of those engines, and to be listed above many or most (and quite possibly all) of your competitor sites when a viewer has searched using your chosen keywords.
