Gravity is a unique ClickBank metric that provides a relative measure of a product's sales momentum. It calculates how many different affiliates have successfully earned a commission promoting that product over the last 12 weeks.

Sales Potential: A high Gravity score proves that the product converts well and is currently "hot" in the market.
Competition: While a higher Gravity suggests more sales, it also indicates much higher competition (not completion). You will be competing against many other marketers for the same audience.

The Scale:
High Gravity (200–800+): Very high sales volume, but extremely competitive. (Note: A score of 1600 is statistically rare; usually, the top products peak around 500–900).
Low Gravity (0–20): Either a brand-new product or one that is difficult to sell. Very low competition.
