In the recent past, many of the experts in SEO field were actually just web developers who knew a thing or two about website ranking. However, search engine optimization is not entirely web design. Rather, it is a combination of effort which makes your site interesting and attractive while giving the information about your presence to customers.
The website is the face of your company when customers are looking for something. In the same way that customers expect to find clean well organized aisles, your website should also be neat and well arranged. The home page should clearly indicate the next step depending on the needs of customers. If your web design is unattractive, customers will lose interest as soon as they land onto your site. Moreover, if customers cannot find what they are looking for easily, they can give up on your ability to actually provide the products once the make the purchase.
