Days on Market (DOM) and Days on Site (DOS) metrics help you analyze how long vehicles have been available for sale. These fields provide critical insights into inventory turnover, pricing strategy effectiveness, and market demand patterns.
Days on Market (DOM) tracks how long a vehicle has been available for sale across all dealers, while Days on Site (DOS) measures how long a specific dealer has had the vehicle listed.
MarketCheck provides five distinct time-on-market fields, each serving different analytical purposes:
dom_activedom_180domdom_group_activedos_activeThese metrics are calculated based on the listing lifecycle dates, using intelligent gap handling to account for temporary listing interruptions.
For dom_active, dom_group_active, and dos_active, the starting point may reset depending on listing activity. This is particularly relevant when a vehicle is re-listed after being temporarily unavailable.
For correctly tracking these metrics, MarketCheck uses a 30-day gap threshold to determine whether listing interruptions represent continuous market presence or a new opportunity.
dom_180 and dom fields do not have this gap limitation, allowing for a complete view of a vehicle's market history.
Use DOM fields to understand which vehicle categories move quickly through the market and identify slow-moving inventory.
