When you build a custom shopping campaign, it can take up to 48 hours for data to populate in your dashboard. Why? Our campaign crawlers need time to scour the internet and identify promising leads.
In general, the more filters you set, the longer it will take to receive data. In other words, a targeted search will deliver a smaller quantity of leads but the leads it does provide will be of higher quality.
To receive alerts on your campaign performance, make sure you set up your notification settings.
