When clicking "install Google Chrome", Google sent me to this page: "Get Your Google Back. Take two minutes to make Windows 8.1 more familiar." The page suggests to install Google Chrome ("It's the fast, free browser that's built for the modern web") and get the Google Search app for Windows 8 ("It's the quickest, easiest way to access Google Search").
This seems to be an updated version of the "Get Your Google Back" page launched in 2012 for Windows 8 users. Google tries to explain that you can continue to use Chrome even from the Metro/Modern interface and there's even an optimized Google Search app.
