# Read Best Sellers, Money Makers and Most Growth

Three ranked cards at the top of the Aftermarket Analytics tab call out the model codes worth a closer look. Each card lists the top three model codes for its measure.

### Best Sellers

Ranks model codes by number of sales, shown as **{n} sales**. Use it to see which models move the most units. When there is no matching data, the card shows "No model sales for the selected brands."

### Money Makers

Ranks model codes by total revenue, shown in US dollars. Use it to see which models bring in the most money, even if they do not sell the highest volume. When there is no matching data, the card shows "No revenue data for the selected brands."

### Most Growth

Ranks model codes by growth trend, shown as **+0.123 sales/quarter** or a negative number.

Growth trend tells you whether sales of a model are speeding up or slowing down. Signal looks at sales counts for each of the last 8 quarters and fits a trend line through them. The number is how many additional sales per quarter that trend line points to, on average. A positive number means the model is trending up. A negative number means it is trending down.

When there is not enough recent sales history to draw a trend line, the card shows "Not enough recent sales data to compute growth."

### Notes

* Growth trend only looks at the last 8 quarters. A model with strong sales further back will not show that history here.
* This feature may not be enabled for your organization. Ask your Zephyr Intel contact.
* If your organization's sales data has not been connected, these cards show their empty-state messages instead of rankings.
