SEO marketing is the process of optimizing your website so that it appears above the competition for the keywords that matter most to you in the search results. For example, if you sell blue widgets, you can use SEO Marketing to be able to rank above other people who also sell blue widgets, for the search term ‘blue widgets’ in the Google search results. The higher up the page you appear for your target search terms the more traffic you are likely to get.
Of course this is not something that you are likely to be able to achieve for yourself, you’ll need the help of an SEO marketing agency to help you successfully navigate the sometimes confusing search space. The goal of SEO marketing is to drive more traffic to your site by getting better search engine rankings across the major search engines (particularly Google).
SEO marketing is an offshoot of the broader spectrum of digital marketing also known as online marketing, which includes SEO, PPC, web design, social media etc. To succeed online these days, you really need to be successfully applying SEO marketing techniques to your website. For example, you’ll need to be able to get loads of good quality backlinks to ensure your website appears more popular. However a good starting place is on-site optimization and great original content.
