Google has released some new information this year!
Practical Ecommerce reported, "We knew that more than 50 percent of the sites in Google’s index are mobile-first, but now Google has also confirmed that over 50 percent of sites ranking in Google’s search results pages are mobile sites as well."
If we haven't said it enough yet – make sure your website is optimized for mobile!
We also learned that Google is working on 3D and AR initiatives and that Google's index includes 130 trillion pages. Wow!
