Median and middle 50% of account-level average order values. Each account value is purchase ROAS multiplied by cost per purchase in USD. Successful classifications, including manual corrections, with positive finite spend, purchases, ROAS and cost per purchase. Accounts are counted once with equal weight. Quartiles use linear interpolation. Root cohorts include direct root classifications and their child categories; exact-child cohorts exclude parent and sibling categories. The source selects the highest-spend coverage row per account among snapshots dated within the preceding 30 days; the underlying reporting period is not supplied. This is a dated aggregate advertising-data snapshot, not business-wide AOV or a census.

### How can a starter offer avoid overclaiming?

FTC guidance says an apparent starter fault may instead involve a battery or connection. Creative can show a diagnostic sequence and reserve the actual parts recommendation for inspection.

### What does a parts-condition label clarify?

The FTC separates new, remanufactured and salvage parts. A listing can state the actual condition and included components, while any fit or warranty terms require the seller’s own evidence.

### Why show labor separately from a component?

The FTC says a repair estimate identifies parts and anticipated labor charges. An ad can direct buyers to an itemized quote rather than suggest a component price equals a completed repair.
