A plain-language explanation
Google Shopping is part of the Google ecosystem presenting product offers with prices, photos, seller names and availability information.
Where it helps in practice
Shopping compares offers through product data, price and merchant quality, so creative cannot compensate for a wrong variant or unavailable stock.
The decision before implementation
Separate free listings from paid campaigns and choose promoted products with margin in mind.
How to verify the result
Measure approved-offer share, sale cost, profitability, variant errors and returns following product clicks.
