Hello there!
When you first create your campaign, we perform a rush collection to gather data for your site. Generally you'll start to see this information come through within 24 to 48 hours of campaign creation. You can check out the Rankings tab of your campaign to see if they've arrived!
However, if you added new keywords after the initial creation of your campaign, they will not be included in this rush collection and you will need to wait until your next weekly crawl to see results. It's difficult to tell which case this is without looking at the campaign, but if you have additional questions please contact us at help@moz.com to take a look!
