Recommended reading path
Read these guides to understand formulas, examples, comparisons, and practical use cases.
Some marketplace ad programs can improve visibility and sales rank while making per-order economics weaker, so sellers need a time-based view of tradeoffs.
Underpowered retail media tests can produce false confidence because bid data, ranking movement, and conversion behavior have not had enough room to stabilize.
ACOS and TACOS answer different questions, and sellers usually need both views to understand whether marketplace ads are helping or merely shifting margin.
Marketplace advertising can look strong in surface metrics while quietly becoming too expensive after fees, discounting, and mixed order quality are included.
Marketplace ads can drive incremental sales, but sellers need to know the break-even point after ad cost, fees, and fulfillment are combined.
Retail media budgets need a different planning model because platform fees, margin pressure, and marketplace ranking effects all change the math.
