Think of the UVP as the finished story benefit (or outcome) the customer gets after using your solution.
Solution: Job recruitment service
UVP: Find your dream job in 60 days
Your UVP is a promise of the outcome customers get, while your solution is describes how that outcome is achieved.
I could easily substitute "Job board website", "Resume builder", or "LinkedIn" for the solution above while keeping the same UVP.
Takeaway: A good UVP is outcome versus solution focused.
