Once people started visiting your website, are they going to spend more time browsing your pages? Or do they click in for a peek and leave before doing anything that will convert into profit? These are some of the question before an SEO (Search Engine Optimization) specialist starts building traffic for a specific site. You can analyze your website, by using web analytics just to figure out on how to get more traffic that would convert into sales.
Having a quality site is not just focusing on getting tons of traffic, but on how we could make this traffic converted into sales or in SEO, we called it ROI (Return of Investment). In optimizing a specific site, you must have a rich keyword saturation in order to get ranked (mostly the title tag). Once you achieve this, you had provided what users really want. That´s the missing piece of the puzzle and to the factor that causes many people scratch their heads in disbelief.
