A Exact Monthly Search Question - Amazon Affiliate

Hi All,

I have a fairly rudimentary question regarding Exact Monthly Search (EMS) while building a website for Amazon affiliate marketing.

So this would be my first endeavor in building a website around Amazon products. I'm treating this more as learning website than a real money earner however I would still like it to make something and not be a complete dud.

Q1. 3 products targeted - falls in the range of $50 - $75 what should be the minimum EMS (combined for all 3 products) that you would bother with if say the target is to make $100/month

I assume all three products in the same category and you're going to build an amazon niche website. If yes, 3k EMS + if you're able to make those 3 KWs in first position of google would bring you $100/month.

Kindly correct anyone if I'm wrong with my Math
