I write you because Page Speed test is a wonderfull tool but it's not possible to make a Page speed test as a mobile in order to check mobile version of a website.
It means that it is impossible to follow improvements as on a desktop version and it's really a shame.
Do you plan to purpose this ?
Thanks for the feedback Samuel! We are considering this for sure. Page Speed throttling and emulating (emulating for mobile would be one feature there). We've had this request a few times, and I think it makes sense and is very valuable. Thanks again for the feedback. Keep it' coming!
