Like lots of folks I moved to a mobile friendly wed design this spring, the move went pretty much well. My pages all recieved the coveted "Mobile Friendly" label in the mobile serps. Mobile traffic increased quite a bit, which was nice.
But...
A small number of my pages used a modified layout that I wasn't totally happy with. These are my highest trafficked "landing pages" bringing most of my mobile and other traffic to the site, so making a change was a bit nerve wracking.
Anyhow I finally got around to modifying the layout again and of course ran the new layout through Google's Mobile Friendly Test tool. Those pages ALL returned an "Awesome" result from the Mobile Friendly Test tool.
Those pages promptly all lost their Mobile Friendly label in the mobile serps. The incoming Mobile traffic to those pages took a corresponding hit. Interestingly, for the most part those pages maintained the spot in the mobile serps, any changes were only maybe one place.
Makes me think that the "Mobile Friendly" label may be more important than I had thought before.
And more importantly that the Mobile Friendly tool needs to be looked at only as a crude reference point in the design process.
