Google Chrome’s Data Saver mode can now show HTTPS webpages as Lite pages
There have been multiple studies done that show people will abandon a website if it takes too long to load. This makes perfect sense if a website is taking 10+ seconds to load (especially on mobile), but the data shows that a considerable percentage abandon a site if it even takes it a second or two longer than expected. Google has done a lot of work to improve website load speeds with the use of Data Saver on Chrome for Android as well as its own AMP results. However, the company is taking its Data Saver feature a step further by supporting HTTPS webpages with a new feature called Lite Pages.
This new feature is currently built into the Data Saver feature in Chrome for Android so you can enable or disable this feature by toggling that feature. This means that Google isn’t forcing this on everyone and it can be easily disabled within Chrome’s settings. But Data Saver in and of itself is quite useful and can reduce data usage by up to 90% and load pages two times faster. This is great for specific areas with slow or poor mobile connectivity as it helps a larger fraction of pages actually finish loading. Now, it also works on the more secure HTTPS webpages.
So a Chrome Lite Page works by having the Data Saver feature on which lets the company use their own servers and built-in optimizations to improve page loading even more. Interestingly, the specific optimizations that are used will depend entirely on what part of the world you are from. Not only that, but it will also depend on how the developer wrote and served a particular page. It should be known that these optimizations are only going to be used when Chrome detects “when the loading experience would be painful to users.” You will see an icon in the URL bar when a Lite page is being displayed.
So you should only see these Lite pages if your online connection is 2G, “slow-2G,” or when Chrome estimates the website will take more than 5 seconds to load. The inclusion of HTTPS webpages is very important for browsing the web securely. Those who want to use this feature even when they are on a faster connection can set #force-effective-connection-type to any 2G option via chrome://flags. You can also enable #ignore-previews-blocklist to prevent automatic disabling of the feature as a result of users opting out
