Search engine optimization (SEO) refers to methods used to increase traffic to a website by increasing its search engine page rank. SEO often involves improving the quality of the content, ensuring that it is rich in relevant keywords and organizing it by using subheads, bullet points, and bold and italic characters. SEO also ensures that the site’s HTML is optimized such that a search engine can determine what is on the page and display it as a search result in relevant searches. These standards involve the use of metadata, including the title tag and meta description. Cross linking within the website is also important. earch Engine Optimisation (SEO) is the practice of increasing the number and quality of visitors to a website by improving rankings in the algorithmic search engine results. Research shows that websites on the first page of Google receive almost 95% of clicks, and studies show that results that appear higher up the page receive an increased click through rate (CTR), and more traffic.
SEO, therefore, involves making sure a website is accessible, technically sound, uses words that people type into the search engines, and provides an excellent user experience, with useful and high quality, expert content that helps answers the user’s query. Google has a very large team of search quality raters that evaluate the quality of search results, that gets fed into a machine learning algorithm. Google’s search quality rater guidelines provide plenty of detail and examples of what Google class as high or low quality content and websites, and their emphasis on wanting to reward sites that clearly show their expertise, authority and trust (EAT). Google uses a hyperlink based algorithm (known as ‘PageRank’) to calculate the popularity and authority of a page, and while Google is far more sophisticated today, this is still a fundamental signal in ranking. SEO can therefore also include activity to help improve the number and quality of ‘inbound links’ to a website, from other websites. This activity has historically been known as ‘link building’, but is really just marketing a brand with an emphasis online, through content or digital PR for example.
