How do you find keywords to target?

Specifically for Clickbank, sometimes you find a good program to promote. You see it like "Vladimirs Forex Club" ...

I'd like to promote this, but what would I target on Google if I'm doing SEO?

Would it be just "vladimits Forex Club review" or would it be "Forex mentor" "Forex Club" or "make money with Forex" I don't exactly understand.

I'm not asking to be spoon-fed, I'd just like to know the basics.

You need to decide which angle is more easy to target, example the review angle is the hardest because everyone will target it, if you target forex mentor or club will be more easy to rank. When you target a product list different angle everytime and search which will be the easiest

Sometimes even good clickbank product names don't get enough searches to target the name brand as a keyword. Like if billy jeans weight loss secrets was your product that name might get 5 searches but organic weight loss will get a lot more. Go for traffic keywords and introduce the products.
