To put it simply, Search Engine Optimisation (SEO) means taking a piece of online content and optimising it so search engines like Google show it towards the top of the page when someone searches for something.
SEO is important because it is specifically aimed at improving the online presence and traffic for a website. SEO helps you show up at the most important stage of your customer’s journey, when they are actively looking for products and services you offer, or resources and information about related businesses.
