This, like pay-per-click, can be expensive and may not benefit your website as much as you might expect. SEO Agencies base their understanding of search engine algorithms on a set of parameters which have been shown to work on other websites; there is no formula or secret knowledge that SEO specialist's can boast, simply relevant experience and an understanding of the way the system works. When you enter a search term (also known as a keyword) into Google, Google then scours the internet for content (i.e., wording) related to your keyword. There are other methods of driving traffic to your website, including via social media, online advertising, referrals from other websites, and more. However, search engine traffic remains one of the most common and cost-effective methods of receiving traffic.
