Aggregate reports tell you what happened on average. Sometimes you need to know what happened to one person: which ad they first clicked, how many times they came back, and what finally made them buy.
Each person in BrainyMetrics has a page with their lifetime value, identifiers (emails, phones, Stripe and Shopify ids), every browser linked to them and how it was linked, and a full timeline. Every session shows its source, campaign, ad set and ad, device and engagement, with the pages and actions inside it. Badges show how much credit each session received, and you can switch the model right on the timeline.
