Which of the following tools can an advertiser use to create a custom audience from people who recently visited their website homepage?

The correct answer is Amazon Ads Tag because this tool enables advertisers to create custom audiences based on the behavior of users who have recently visited their website, including the homepage. By implementing the Amazon Ads Tag on their site, advertisers can track visitor interactions and then retarget these users with relevant ads on Amazon, effectively re-engaging potential customers who have shown interest in their offerings. In contrast, advertiser hashed audiences are typically used for securely uploading customer data, while lookalike audiences are designed to find new customers similar to existing ones but do not specifically target recent visitors to a website, making the Amazon Ads Tag the most appropriate option for this purpose.
