This feature differs from the 'Sale' feature and has a strong influence on attracting more attention, helping potential buyers identify the best deals available.
The Price Drop Annotation can be used as part of a pricing strategy for retailers selling the same products as competitors, making their ad stand out from the competition.
Lowering the regular price of a product is attractive for consumers who are price-sensitive, and the benefit of the price drop badge is that it can make your ad stand out.
