After tracking Amazon’s Search Query Performance report, I’ve concluded that organic ranking is driven by market share – specifically the ASIN Share column. This represents the percentage of total keyword orders that your ASIN captured during the selected period.
In other words:
ASIN Share = (Your keyword orders) / (Total keyword orders)
To reach the top 3 organic positions, you need a sufficiently high market share. You can check your own data to see if this holds true.
Since Orders = Traffic × CVR, to gain higher market share than competitors, you either need:
-
Higher click share (more traffic), or
-
Similar traffic but higher conversion rate.
Actionable strategies derived from this:
-
Your CVR must be at least average. If you rely on ad traffic to push market share with below‑average CVR, you’ll struggle to be profitable.
-
Target long‑tail keywords first – their “market share” denominator is smaller. One order can give you a very high share, pushing you to top 3 organically. Long‑tails then help lift head term rankings.
-
When organic rank is low, use ads to get traffic while maintaining above‑average CVR to build market share.
-
Once market share is secured and organic rank rises, gradually lower bids to replace ad positions with organic ones, balancing traffic and profit.
I’d love to hear if others have observed the same – does higher ASIN Share consistently correlate with top organic positions?

That would be true if ads didn’t exist. When your organic rank is on page 2‑3, you can use ads to get top‑of‑search placement. Good CVR then increases your market share, which in turn lifts organic rank. Once you’re in the top 3 organically, you can either keep ads running to monopolize, or reduce bids to shift spend to other keywords.
If your own logic works for you and brings profit, that’s what matters.
