The Google Page Speed score is a rating that provides information about the speed and performance of your website. The page speed score is calculated using various factors, including the number of requests it takes to load a webpage, and the time it takes to return the first page of search results for a given query.
Google uses this score to help determine the rankings of pages that take longer to load, and to help users choose the fastest website when they do a search. While the Google Page Speed score is useful for pages that require heavy traffic, it can also be used to compare the performance of different versions of a page. Google provides a list of things that can affect the score, including: The file size of the initial HTML document.
