Which of the following components of retail readiness could negatively affect campaign performance?

Low product inventory can negatively affect campaign performance because if a product runs out of stock, ads for that product will stop running, leading to wasted ad spend and missed sales opportunities. Customers who click on an ad only to find the product unavailable are likely to have a poor experience and may not return. A star rating of 4/5 is generally considered good and would not negatively impact campaign performance; in fact, strong ratings often improve conversion rates.
