Google Web Light is an initiative by Google
to improve the browsing experience of millions of users who are on slow internet speed. It is also being called as Streamlined lite version of mobile search. Google shows faster, lighter pages to people searching on slow mobile connections in selected countries.
Google web light project is aimed to load the web pages with a faster speed, allowing the web page to load 4X faster, using 80% less data. This will increase the web speed with 50-80% faster results.
The main idea behind the project is to detect the slow connection via browser and transcoding of web page by removing advertisements, & unnecessary elements from the page. To do this, Google transcode (convert) web pages on the fly into a version optimized for slow networks, so that these pages load faster while saving data. These optimized pages preserve a majority of the relevant content and provide a link for users to view the original page. Experiments show that optimized pages load four times faster than the original page and use 80% fewer bytes. Because these pages load so much faster, Google also saw a 50% increase in traffic to these pages.
User will see the optimized web page loaded at a faster speed with less bandwidth / data consumption. A link to the original page will also be provided, so that users can switch to the original page if they want.
