ClickBank Gravity Score Explained

The gravity score is one of the most talked about metrics on ClickBank and one of the most misunderstood. Here’s what it actually measures, what the numbers mean, and how to use it without getting burned.

What gravity actually measures

Gravity is a rolling 12-week score that counts how many unique affiliates have made at least one sale of a product during that window. The score weights recent sales more heavily than older ones. So a product that had 50 affiliates make sales last week will have a higher gravity than one where those same sales happened two months ago.

What gravity does not measure is total sales volume. A single high-volume affiliate driving thousands of sales counts the same as one affiliate making one sale. It’s a breadth measurement, not a depth measurement.

How to read the numbers

Gravity Range	What It Means	What To Do
0 to 10	Few or no affiliates making sales. Product may be new or may not convert.	Avoid unless you have specific intel on the product.
10 to 30	Some traction. Could be a hidden gem or a slow mover.	Research more before committing traffic.
30 to 100	Solid proof of conversions. Manageable competition.	Strong candidates. Evaluate commission and refund rate.
100 plus	High conversion proof but also high competition.	Can work but you need a strong angle to stand out.

The gravity trap most affiliates fall into

Chasing the highest gravity product is a mistake. Products with gravity above 200 are being promoted by hundreds of affiliates simultaneously. You’re competing against people who have been running paid ads to that offer for months and have already optimized their funnels. As a newer affiliate you will lose that fight.

The sweet spot is gravity between 30 and 100. Enough affiliates are making sales to prove the product converts, but not so many that the market is saturated. That’s where most consistent affiliate income actually comes from.

What gravity can’t tell you

Gravity says nothing about refund rates. A product with gravity of 80 and a 25 percent refund rate is losing you a quarter of your commissions before you even see them. Always look at refund data alongside gravity.

Gravity also says nothing about niche fit. A product that converts great for someone else’s audience may convert terribly for yours. The metric measures universal sales momentum, not your specific situation.
