Seo.com provides an illustrated look at reason to redesign your website.
Seo.com says "When you begin a website redesign, always keep the search engines in mind. 62% of search users click a link on the first page of the search results. If they don’t immediately see what they need on that page, 41% of these users won’t bother going to page two. They will simply refine their keywords or switch search engines. 77% of search users still chose organic results over paid ads, so make sure that your website redesign can help propel you to the top of the rankings and appeals to your new customers."
