Two ways of doing it:
1) Use your gut. Put on your psychologist hat. Have a guess.
2) Try a bunch and see which ones make sales. You have to be prepared to burn through some money to figure this out though.
A good place to start is with keywords like "product name review" and "author name review". If anyone is searching for the product name like this, they already know about it, and they're already thinking of buying it.
Next step back in certainty would be keywords like "product type review" "best product types" etc. (Eg, "dog training guide review" "best dog training guides" "best training guide for puppies" etc). These people clearly want the type of product you're promoting, but they're not sure which one yet.
Beyond that it starts getting into guesswork. You need to know your audience and the problems they're facing, and how urgently they need a solution. When people are in some kind of "pain" (not necessarily physical) and need a solution quickly, they are more likely to buy.
