Has anyone ever seen a sudden drop in mobile rankings but desktop searches remain what they were? I have a local business that has been on page 1 for all search keywords since October of 2013. Mobile and desktop rankings were always identical and appeared to be for all the competition as well. Today I noticed that on mobile searches an inner page will be ranked on page 4 or 5 of google, however, the site is still in the 7 pack results and rankings on desktop searches are as normal. The mobile website generator I was using gave a really long, messy looking url but that has always been the same. I disabled the mobile version for now. No warnings in webmaster tools. Only two links built within the last 30 days and did not use overly optimized anchor text. I can't imagine it is penguin, over 90% of inbound links are brand or urls. No more than 2% on any exact match (with all keyword rich links as less than 10% total) which is well under the majority of competing websites. Any ideas?
