Is website optimization a must?

Does my website look good enough already? Do I still need to optimize it? As a new customer trying website promotion for the first time, you might think: I lack basic knowledge about website construction, and website optimization may be too specialized for me. Where should I start?

For these questions, the simplest method is to invite a friend of yours (someone with basic knowledge of computers and the internet would suffice) to conduct a live test on your website. You can observe the process as this "user" interacts with your site.
