Pagespeed is the metric used for the time taken for any webpage to load all of its elements. The quicker a page loads, the better it will rank in search engines – which take this metric into account when indexing websites. As such, technical SEO experts often search for ways to make complex media render faster on websites they work on.
Website owners can also engage with tools to check Pagespeed in order to locate the pages that are performing poorly and, in some cases, swap in or remove content that is slowing the entire rendering time for the page down.
