I have found this time and time again to be the case when discussing web-site development services with clients or potential clients. They will tell me that they already have a web-site that they paid good money for so why should they buy a new one. I have to respond that though they do in fact have a web-site, it is unfortunately unsearchable using search engines such as Google, Ask, Bing, Yahoo, etc. Without their customer or a potential customer actually typing into the web browser the organization's URL, the site cannot be sourced. What a waste of time and money! Bottom line is the site must be able to be searched by search engines and SEO is the key to having it found high on the list.
