When you hear the term SEO, it is likely that someone is talking about Search Engine Optimization, which is the tactical analysis of search rankings, why pages appear where they do and what factors influence their visibility. Currently there are over 200 factors in the search algorithm, with over 3000 updates annually. While the myth that SEO IS DEAD constantly re-appears on popular websites, the fact is that humans are still required to improve search engines. Despite running on elaborate algorithms that can index and sort billions of pages, there are many things that a human can do better than a computer. SEO marketers use their technical knowledge and digital marketing experience to influence and improve organic rankings for businesses online.
