I checked my MOZ account last week to find that my site's Mobile Search Visibility has dropped pretty significantly 4 weeks after an algorithm update. It has ticked back up some but after weeks and weeks of steady position, it fell. I thought the latest update had affected the visibility but I'm not sure that is the case.
One of our competitors ironically jumped UP in Mobile Visibility about as equally as my site has fallen. I've attached a screenshot of the MSV graph. My site is plotted in BLUE and our competition is plotted in PURPLE.
Does anyone have a explanation or potential reason?
