Perhaps in a bid to encourage webmasters and developers to start considering loading times on their websites, Google has announced that they will soon start to identify and badge websites that might take longer to load than usual. As you can see in the screenshot above, websites that take a while to load will show a notice informing users that this page has been known to load slowly.
According to Google, “Badging is intended to identify when sites are authored in a way that makes them slow generally, looking at historical load latencies. Further along, we may expand this to include identifying when a page is likely to be slow for a user based on their device and network conditions.”
This will obviously only apply to websites being viewed on Chrome, so if you’re using a different browser, then this feature won’t apply to you.
