Mobile Friendly Test [Data by Google].

The Mobile Friendly Testing tool is powered by the official Google mobile friendly testing platform, to help you to test and make sure your website is technically optimized for mobile.

Why is a mobile friendly website important?

Because most people are searching on Google with a mobile device. For this reason Google introduced their mobile-first indexing strategy. On September 2020 Google will switch from primarily desktop indexing to mobile-first indexing for all websites. This means Google uses the mobile version of a website to build their indexing and for ranking. Almost all crawling will be done with Google smartphone user agent (here you can have an overview of all Google user agents). To summarize, having your website optimized for mobile is essential to perform well in the Google search results.
