In anything we do we aim for the top slot; except sinning. In academics, sports or business we strive or work hard to be the best. In online business we would like the most visitors to our website hence search engine optimization. This enhances the conversion rate of the visitors into buyers. So when we rank first on relevant searches our business blossoms like flowers during spring. Many of our products will get much exposure and sell more.
Picture a situation where two people are selling identical products at the same profit margin and one is position one on the search engine rating and the other is number thirty. The one at the top will sure sell many times more than the other for buyers will find the products easily on the better placed site. As I have always said human being look for the easiest way out; so any buyer would settle for the one on the top and not bother looking further down the list.
Top ranking websites also give the owners a good business reputation for are seen to be the blue ones in the pack. No matter how your website is; the end result is the most important. In any business venture the ultimate goal is to make the most income from it. So even if your website is so beautiful and so automated but is poorly placed on the search the aim is beaten.
Not only trading websites need to be optimized but also informative one for people will tend to opt to believe information from top ranked ones.
