If you're experiencing no/low notification volume from SiteID, it's likely due to the following conditions:
You recently installed the pixel
If you just signed up, wait a few hours for site visitors to come to your site and our notifications to start flowing.
You haven't enabled an action like Slack
Make sure you've connected Slack and have it enabled in your desired Segment (the default segment is called "All Visitors").
You have low site traffic
SiteID only enriches 15-30% of traffic. If you have a low volume of traffic, SiteID might not be super helpful.
You have low US site traffic
For privacy, SiteID is geofenced to the US only.
