What is the specific benefit of using AliExpress's dynamic bidding options?

The specific benefit of using AliExpress's dynamic bidding options is that they automatically adjust bids in real-time based on the likelihood of a conversion, maximizing the return on ad spend and improving campaign performance. Dynamic bidding uses algorithms to analyze various factors, such as user behavior, device type, location, and time of day, to predict the probability of a sale. Based on these predictions, the system automatically raises or lowers bids to optimize for conversions. For example, if a user is browsing on a mobile device during peak shopping hours and has previously shown interest in similar products, the dynamic bidding system may increase the bid to ensure that the ad is shown to that user. Conversely, if a user is browsing on a desktop device during off-peak hours and has not shown prior interest, the bid may be lowered. This automated optimization helps to ensure that ad spend is focused on the most promising opportunities, leading to higher conversion rates and a lower cost per acquisition (CPA). Dynamic bidding also reduces the need for manual bid adjustments, saving time and effort for advertisers.
