Clear delivery terms help buyers decide
A delivery charge that appears only at checkout can change a buyer's decision. For example, a shopper clicks an ad for a gift, adds it to the cart and discovers that delivery misses the occasion. You still pay for the ad click, whether the shopper completes the order or leaves.
Suppose your store offers free delivery in Dubai but charges for delivery to Fujairah. Your ad can describe the product without implying that delivery is free everywhere. The product page can show both rules and the expected arrival time, so each shopper can assess the offer before adding it to the cart.
Your store can place delivery costs, coverage and return terms beside the product price, including on a small phone screen. This helps because buyers can compare the full offer before payment instead of finding new conditions at checkout. The online store advertising guide explains how to connect your ad, product page and purchase measurement.
