I have a site which ranks really well for certain keywords, sometimes taking up all 10 of the first results on Google with its website, social pages and related domains. However, when I do the same search on any modern phone I get results that are totally different with competitors taking 4th or 5th spots. What should I focus on to take these last spots? Any website that I have is already mobile friendly and passes Google checks for optimization and mobile. Can I do anything with Facebook pages, Google+, Twitter etc. to rank these higher? Any social networks that are really good to focus on?
