Spectare now measures its own lift. A live holdout serves a small slice of visitors your default page, and personalisation is scored against it as a statistical interval: no lift number is quoted until the interval clears zero. Winners on the confidence dashboard are called with statistics that stay valid however often you check, evidence resets automatically when you edit the content it was based on, and when the data supports a rule or targeting change, Spectare shows you the evidence and waits for your approval. Every workspace runs this now, on every plan.
This is one atom from the Spectare content library. Spectare assembles the right atoms for each visitor in real time, based on who they are and how they arrived.
