Average Selling Price (ASP) measures the average price at which a product or service is sold over a defined period of time. It can be calculated for a single product or service, a group of products, a sales channel, or an entire business. ASP is commonly used to compare performance across businesses, segments, or channels and serves as a strong indicator of what customers are willing to pay for similar products or services.

Average Basket Size (ABS) is an ecommerce metric that measures the average number of items purchased per transaction. It is calculated by dividing the total number of units sold by the total number of transactions over a given period. ABS helps businesses understand whether customers are buying more or fewer items each time they place an order. Average Basket Size is also a key input for calculating Average Order Value (AOV) when combined with Average Selling Price (ASP), helping teams distinguish whether revenue changes are driven by quantity, pricing, or both.

Return on Ad Spend (ROAS) is a marketing metric that quantifies the total revenue generated for every dollar spent on advertising. In other words, ROAS measures the effectiveness of your advertising efforts by comparing total ad spend on campaigns to the revenue from those campaigns.
