What are Reddit dynamic product ads?

You supply a catalogue, which is a product feed: a structured file with titles, prices, images and availability. Reddit builds the ads from it. You do not write each one by hand.

Reddit also needs to know what people do with the products. Its help centre says the catalogue is mapped to the Pixel or the Conversions API, and the events it expects are ViewContent, AddToCart and Purchase². The product ID in the catalogue and in those events has to match². The events come from the Reddit Pixel in the browser, the Reddit Conversions API from your server, or both.

So the format is simple to describe. Setting it up is mostly a tracking job. For where Reddit sits among your other channels, read paid media strategy for ecommerce.

Wrong price in the feed, wrong price in the ad. Product out of stock in the feed, ad for a product you cannot ship. The ads update themselves, so the mistakes do too.

The same goes for events. If Purchase events are missing, the ads cannot learn from sales. If they are counted twice, your reported results look better than they are.

You choose when you set it up. Reddit's help centre describes two audience types: prospecting, which looks for new people, and retargeting, which reaches people who already showed interest in your products on your site¹. Retargeting means ads to people who have already been on your site or app. The audience type cannot be changed after the catalogue is set up¹.

In our view, retargeting people who were already in checkout collects credit for sales that were likely to happen anyway. Ask what share of the revenue came from them.
