For the past few years, Google has been consistently pushing the website owners to improve their mobile site experience. They have launched multiple algorithms, guidelines, and tools for the same purpose.
Recently, at Mobile World Congress, they launched two new tools, a new Mobile Scorecard and a Conversion Impact Calculator.
The mobile scorecard provides data on the chrome user experience so that you can compare the speed of multiple websites on mobile devices.
The mobile scorecard pulls data from chrome to compare the speed of multiple sites on mobile. That’s the same data that Google uses in the Page Speed Insights tool.
Google said that a website should load within 5 seconds on 3g connections and 3 seconds on 4G connection.
