When a search term is entered into one of the major search engines the most common way to display the resources found (web pages, images, videos etc) is through a series of ordered pages (by rank of the material) which are called the Search Engine Results Pages. It’s worth noting that the overwhelming majority of the traffic goes to the first five items on the results and very few people will ever look beyond page two. This only goes to highlight the importance of Search Engine Optimisation and ranking well.
