Google launches mobile suitability assessment tool

A new resource has appeared in the list of Google projects, intended for website owners and developers - https://testmysite.thinkwithgoogle.com . With it, you can determine whether the mobile version of the site is suitable for use from the point of view of the three parameters that Google exposes:

• Mobile-friendliness
• Mobile speed - site loading speed on mobile devices
• Desktop speed - download speed on the desktop

Each score is ranked in points from 0 to 100, and the result of the check Google suggests sending to the webmaster so that he can take some action if necessary.

The results of testing the mobile version of Habrahabr can be seen in the screenshot:

In the mobile version of Geektimes, the situation with the download speed is also far from the best:



After a little study of the site, it becomes clear that the search giant just organized a convenient interface to one of its APIs - PageSpeed ​​Insights. A GET request with two different platform identifiers is sent to it twice: mobile and desktop. In this regard, you can easily find out the criteria by which Google assesses the download speed of the site and its suitability for mobile devices. Google pays the most attention to two indicators.

• load time of the upper part of the page : the total time from the moment the page is requested to the moment it is displayed in the browser
• full page load time : the total time from the moment the page is requested to its full display in the browser.

After clicking on the rectangle with the results of a specific test, you can look at the recommendations that Google issues for this site. Apparently, the mobile version of Geektimes has problems with image optimization and too much JavaScript, which you have to wait for the elements to render. True, the business of m.google.com, according to Google itself, is also very far from perfect:
