Mobile-first / above the fold requirement?

Dear Community,

I hope this is the right location to post my concern resp. question:

Over the last couple of months I updated my web presence and tried to take into consideration all new requirements which came up with the mobile first update of Google in spring / early summer this year.

So now here is my problem / question: My understanding is that one of the new requirements of Google with has a huge impact on search results is that only content (that means text, not an image anymore) appears when a user visits the site with his mobile device.

I restructured all my sub sites in order to reflect this requirement, as you can see here for example here: Akku-Rasenm?her Test.

As you can see, the website start with some text (to reflect the requirement described above) and only shows the introducing image afterwards.

Does anybody know if my understanding of this google requirement is correct? As I really would like to continue starting with the image instead of the text.

Your feedback would be highly appreciated.

Alex
