Verdict states
The Spectare admin now includes a Confidence page that tells you whether the leading variant in each audience and funnel segment is a genuine winner or simply ahead by noise. Rather than declaring a winner the moment one variant clears a raw conversion volume threshold, Spectare computes Wilson score intervals for every variant and only calls a winner when its worst-case rate still beats the runner-up's best-case rate. That is a stricter and more honest bar than a standard two-proportion significance test.
Every combination of audience, funnel stage, and intent type gets its own verdict. The verdict is one of three states: insufficient data to say anything meaningful, gathering data with a trend emerging, or a significant winner that is statistically real. The page sorts cells so the most conclusive ones appear first, letting you act on strong signals without wading through thin ones.
The page also shows how many more impressions the thinner arm would need before the leader separates to significance, calculated using the same non-overlapping Wilson criterion that governs the badge itself. The projection is consistent with when the status actually flips, so the estimate you see is the same number the system is working toward rather than an optimistic shortcut.
At the top of the page an org-level maturity header shows your overall conversion volume and current exploration rate, so you can see at a glance whether your site is still in an early learning phase or has enough history for the confidence verdicts to carry real weight.
