Obviously I don't know your situation but you might be running across an issue with expecting one person to do the job of many. There are so many aspects to SEO that its near impossible for one person to be an expert in every area. Content, social media, on-page optimization, user experience optimization are all vital components to a successful digital marketing plan. At best, a "genius" SEO can only be great at one or two, but not all. It might be time to invest in a team. That might mean hiring an agency, but you truly do get so much more experience with a team than one person.
