Google wants its users to have an enjoyable experience when using its search engine, and one of the biggest factors that affects this is the speed at which web pages load. Google knows that if a page takes too long to load, the user may become frustrated and move on to another search engine. To prevent this from happening, Google wants to make sure that pages are loading quickly.

By improving site speed, Google can save money on its bandwidth costs, since it will not have to serve as much data to users. Furthermore, a faster website makes it more attractive to Google’s search engine spiders, which crawl the web to index pages and serve up search results. The faster a website loads, the more quickly the spiders can index and serve up the page’s content, which means that users will get their search results faster. Additionally, a faster website also means that the spiders can crawl more pages in a given amount of time, leading to better search results.
