Great question! I am presuming you are asking this question because an SEO company has stated that they have a special relationship or partnership with Google. If this is a case, I would quickly rip their proposal up and put it in the bin. There is no SEO company in the world that has a special relationship with Google, and in my mind, never will.
There are certain certifications that you can gain from Google, such as becoming Google Analytics or Google Adwords certified; but this just shows that you understand how to use their products and not that you will get an artificial push in their search results pages. There are only a limited amount of people in the world that know snippets of information about Google’s algorithm as this is their “secret weapon” and why they have become one of the most powerful companies in the world. They don’t give out these secrets to any SEO company.
