One of my websites has always ranked top 3 for a set of competitive keywords relating to mobile traffic.
The other day I checked the term on my iPhone and noticed I was no longer listed. I checked on my wife's iPhone and the same thing.
I tried it on an iPad, and the site is still ranked at number 2 for all searches.
I tried it on desktop and it is also ranked at number 2.
My SERPLAB tracking shows no issues and all terms ranked at 1 or 2.
So what's going on? Why has this site been dropped from iPhone mobile SERPS? All other results on the first few pages for these terms are identical across mobile, iPad and desktop - i.e. it's only my site that seems affected.
