SEO is just one way of getting visitors

The main purpose of SEO is to make your site visible to search engines, thus leading to higher rankings in search results pages, which in turn brings more traffic to your site. And having more visitors (and above all buyers) is ultimately the goal in sites promotion. For truth's sake, SEO is only one alternative to promote your site and increase traffic – there are many other online and offline ways to do accomplish the goal of getting high traffic and reaching your target audience. We are not going to explore them in this tutorial but just keep in mind that search engines are not the only way to get visitors to your site, although they seem to be a preferable choice and a relatively easy way to do it.
