Criteo imports your product feed daily – from the url provided in the feed configuration. That way, we always have accurate, up-to-date product information.
Once the first import is complete, you can then set a specific time and time zone for the feed update.
If you update your feed at a specific time, we recommend that you configure your Criteo feed import directly after, to make sure any changes are reflected immediately on Criteo side.
For more detailed information, see our article on how we retrieve your feed.
