The movie (and Visual Dictionary) revealed a lot about Snoke, actually.Snoke calls Darth Vader as "Lord Vader," suggesting Snoke was of the Imperial hierarchy.
Further, we now know that Ben isn't a Vader fanboy. Snoke is. Ben wants to be like Vader because Snoke will beat his ass if he isn't.
Snoke also has a ring with a fragment from Vader's Mustafar castle from Rogue One.
Then we have Snoke recreating the Empire to a T, from hierarchy (ex. Ben and Hux) to clothing (the purple Emperor advisors).
In short, I'd say it's safe to say Snoke was some dark-side wielding person within the Empire who looked up to Vader and Sidious.
A dark side acolyte similar to those shown in Dark Empire, perhaps.
When they both died, he was determined to recreate their accomplishments and honor their legacy.
sidious in ROTS and in rebels calls vader lord vader
what about the first jedi theory
