What to do
From these segments' numbers. Setting buttons fill in the Build segments tab (then Build segments); merge buttons change the table below (then Save labels, no refit).- Worth doingordered: use S5, S2, S6 as the targets on Outcomes
S5, S2, S6 hold 37% of ordered in 13% of the snapshots (2.8× the overall rate).
- Fine as isUnknowns: 1.1% of snapshots
A small unknown share means nearly everyone fits a segment, while the odd ones aren't forced in.
Outcome concentration
Share of each segment's snapshots whose entity eventually had the outcome. Lift = rate ÷ overall rate.S5 has the highest rate: 18% for ordered, 4.6× the overall 3.8%.
- S5 has the highest rate: 18% for ordered, 4.6× the overall 3.8%.
- Rate: share of a segment's snapshots whose entity eventually had the outcome. Everyone together: 3.8% for ordered.
- Lift = rate ÷ overall rate. S5 has 18% for ordered, so 4.6× the average; above 1 is better than average.
- Captured: the segment's share of all the outcomes (each Captured column adds to 100%). Compare it with Share: S1 is 78% of snapshots and holds 48% of ordered, so it dilutes it.
- Segments that capture much more than their share are the ones to take to Outcomes as targets.

How each segment differs
Average of each input, in standard deviations from everyone. Red higher, blue lower.landingPage=/product/474-port-and-prune-pudding-800g-log-in-cloth separates the segments most: from -0.1 sd in S3 to +8.3 sd in S6.- Each column is a segment and each row an input. A cell is how far the segment's average sits from everyone's, in standard deviations: +1 is clearly higher than typical (red), −1 clearly lower (blue), and near 0 is typical. Below, "slightly" means under 0.6 and "much" means over 1.5.
landingPage=/product/474-port-and-prune-pudding-800g-log-in-clothseparates the segments most: from -0.1 sd in S3 to +8.3 sd in S6.- S1 (1,751 snapshots): slightly more often landingPage is / (+0.3).
- S2 (171 snapshots): much longer-standing (returning) (+2.8); much more visits so far (+2.6).
- S5 (91 snapshots): much more often source is Direct (+3.7); much more often landingPage is /product/75-christmas-cake-boxed (+2.5); lower newVisitor (-1.0).
- S3 (89 snapshots): much more often landingPage is other (+4.3).
- S4 (88 snapshots): much more often landingPage is /product/79-chocolate-fruit-cake-500g-boxed (+4.9).
- S6 (32 snapshots): much more often landingPage is /product/474-port-and-prune-pudding-800g-log-in-cloth (+8.3).
- Read a segment down its column to describe it; read across a row to see which segments differ on that input.

Movement between segments
Where each entity's next snapshot lands, as a share of the rowThere are 232 steps from one snapshot to the next. 28% stayed in the same segment, so people often change segment between visits.
- Rows are where an entity's snapshot was; columns are where its next snapshot landed. Each row adds to 100%. The diagonal is staying put; anything else is a move.
- There are 232 steps from one snapshot to the next. 28% stayed in the same segment, so people often change segment between visits.
- Most common moves: S1 → S2 (118); S1 → S3 (8); S1 → S4 (6).
- S5 has the highest ordered rate (18%). Entities arriving there mostly come from S2 (3), Fits no segment (2): that's the path worth watching.

Segments over time
Share of snapshots per weekFrom the first week (05 Oct 2026) to the last (26 Oct 2026), S2 grew the most (+12% points) and S1 shrank the most (-26% points).
- Each bar is one week: how that week's snapshots split across the segments (100% per bar). Hover a block for the count.
- From the first week (05 Oct 2026) to the last (26 Oct 2026), S2 grew the most (+12% points) and S1 shrank the most (-26% points).
- The table underneath gives each segment's ordered rate per week. A rate that holds steady is dependable; one that swings may be seasonal, or the segment may be too small. The first and last weeks are often only part weeks.
- Watch here for change: a segment growing, or its rate drifting, is the signal to rebuild the segments or rethink an action.

How good are these segments?
Separation 0.64 (clear) and stability 0.88 (very stable). Least stable: S7.
- Separation (silhouette): for each snapshot, how much closer it sits to its own segment than to the next nearest. 1 is perfectly apart, 0 is on the border, below 0 is closer to another segment. Above 0.25 is reasonable, above 0.5 clear. Here: 0.64, clear.
- Stability: the segmentation was refitted 3 times on different 80% samples. 1 means the same segments came out every time, 0 no better than chance. Here: 0.88, very stable.
- Least stable: S7. A segment that doesn't come back when refitted is a quirk of this fit: don't build an action on it alone.
- Confidence: the average probability with which snapshots were placed in their segment.
- The best segmentation for a decision is one that is stable and concentrates the outcome. Compare runs in the table at the bottom of the page.

Choosing the number of segments
Each bar is how well separated the segments are (silhouette) for that number of segments. Higher is better; the best, 8, was used.
- Each bar is how well separated the segments are (silhouette) for that number of segments. Higher is better; the best, 8, was used.
- K-means doesn't use the BIC score: it has no probabilities, so it's judged on separation instead.

The unknowns
24 snapshots (1.1%) are unknown: 0 too little history, 1 between segments, 23 fit no segment.
- 24 snapshots (1.1%) are unknown: 0 too little history, 1 between segments, 23 fit no segment.
- Too little history (0, 0.0%): fewer rows so far than the minimum you set.
- Between segments (1): no segment was a clear best fit; often someone changing pattern.
- Fits no segment (23): the oddest snapshots. Worth a look: new behaviour (or fraud) tends to show up here first.
- Nearest segment says which segment each would have joined if forced.
| Kind | Snapshots | Nearest segment |
|---|---|---|
| Unknown: between segments Sits between two or more segments; often mid-transition. | 1 | S1 (1) |
| Unknown: fits no segment Doesn't resemble any segment. Worth a look: new patterns and fraud often start here. | 23 | S1 (11), S8 (7), S2 (2) |
Boundary rules
How to recognise each segmentTogether the rules agree with the model 94% of the time: good enough to use as a description.
- Read each line as IF these conditions THEN this segment, using the inputs in their own units (minutes, page counts).
- Covers is the share of the segment the rule finds; correct is how many of the snapshots it finds really are in that segment.
- Together the rules agree with the model 94% of the time: good enough to use as a description.
Each segment gets its own short rules for picking it out from everyone else, in each feature's own units. Taken together, simple rules reproduce 94% of the assignments. Rules show where the lines fall, not why: use the profile above for what defines a segment. Unknowns have no rules; they come from how well a snapshot fits, not from where it sits.

Compare runs
Find the best segmentationThe pick is v20: its targets hold 83% of ordered in 25% of snapshots (3.3× the rate), with target stability 0.52.
- Each row is one segmentation run. Click the version to open it; the highlighted row is the one shown above.
- Separation and Stability describe the whole segmentation: are the segments distinct, and do they come back when refitted?
- The last four columns are about ordered: Targets are the segments at 1.5× the overall rate or more; Captured is the share of all ordered they hold (and the share of snapshots they are); Lift is how concentrated they are; Target stability is whether those particular segments come back when refitted.
- Read Captured and Lift together: a high lift on a sliver of the outcome is less useful than a slightly lower lift that holds most of it. pick marks the best mix: captured × lift, with full credit only when the targets' stability is 0.5 or more. ★ marks the best value in each column.
- Change one thing per run (the group handling, the number of segments, the shape or the feature set) so you can see what made the difference. Runs built before this table existed show '-'.

Every setup was fitted on the same 1,828 training snapshots (1,611 people); the 20% of people held out for testing weren't used, so Outcomes can still test the winner honestly.
- Every setup was fitted on the same 1,828 training snapshots (1,611 people); the 20% of people held out for testing weren't used, so Outcomes can still test the winner honestly.
- Score = share of ordered captured × lift, with full credit only when the target segments' stability is 0.5 or more. Setups with over 25% unknown are halved.
- Stability is for the whole segmentation, Target stability just for the target segments. A setup with a slightly lower score but much higher stability can be the safer choice.
- Build on full data makes the real segmentation with that setup on everyone. It then appears below as a normal run: name the segments, compare, take it to Outcomes, and export it.
