How would you position your product to a customer. Do you realize that there are at leas a billion points of view?
So think of it as looking at the product and it's description and what it means for the customer. And if this point of view changes because an branding improvement was brought in then you need that page name changed.
Example: Changing from Eternal Glow to Internal Spark
Why: This might happen because you were broadly focusing on the nature of the effect the product produces, and you want to change to the instant the client realizes that the product is transformational. Yes?)
