Google has created an all-new version of its ‘Test My Site’ tool which allows website owners to measure performance and get a report on potential technical improvements. Even if you don’t believe that shaving time off your site’s loading time will get more people reading it (and you’d be wrong to think that, by the way), then perhaps the fact that loading time makes a difference in search engine rankings might sway you to get someone technical to take a look at improving things.
Google’s page speed ratings are generated from what it calls Real User Measurements – metrics taken directly from real-world users using the Chrome browser to visit your website. They might not be what you see, but it’s an example of how Google is using the vast amount of data it has from different sources. “Milliseconds can earn millions“, according to Google.
