Online marketing, also known as Internet marketing, is an essential part of establishing your presence on the web. Creating a website for your business is a start, but the next step is to let people know that your website exists and to get customers on to your website. Internet marketing is a broad term and covers specialist aspects such as SEM (Search Engine Marketing), SEO (Search Engine Optimization) and e-mail marketing among others. Your online marketing budget may include costs associated with placing banners or text ads on other websites or on SERPs (Search Engine Results Pages).
