Classify one search event at a time
This original six-event log stores result count and whether a click was observed. Zero results is one class. With results, clicked=false is no-click and clicked=null is unknown click evidence. The no-click fraction uses every result-bearing event as its stated denominator; unknown clicks remain separately reported. This is a sample log, not Asteratek analytics.
| Event | Result count | Click observed | Class |
|---|---|---|---|
| S1 | 0 | No | Zero results |
| S2 | 0 | No | Zero results |
| S3 | 2 | No | No click |
| S4 | 1 | No | No click |
| S5 | 3 | No | No click |
| S6 | 2 | Yes | Clicked |
Keep both denominators beside the counts
Zero-result searches are 2/6. Three of the four result-bearing searches have no click: 3/4. There is one clicked search. None of these counts establishes that an answer worked, why a reader left or whether the search came from Google.
- Count unique recorded events
- Separate zero-result events
- Classify clicks only with evidence
- Report unknowns and denominators
Unknown results or click evidence is not silently counted as success or failure.
S3’s click evidence becomes null. Is the no-click count still three?
Show the worked answer
No. Two no-click events remain, one is unknown-click, and one is clicked. The stated result-bearing denominator remains four, so report 2/4 plus one unknown-click event.
Prepare a search-gap worksheet
The complete JSON material includes the baseline and changed-click case. Use the table/Markdown sheet to annotate a later observed export, retaining source window, event grain and unavailable fields. Do not paste customer query text into a public sample.
Results must be a whole count 0–1,000 or null; click evidence is true, false or null. A clicked zero-result event contradicts this contract and is rejected. A zero result-bearing denominator has no percentage. Repeated IDs or more than 30 events are rejected.
A zero-result gap may need a reader-permission check before new content is commissioned. Use this worksheet to prepare a search-analysis brief; measure actual task outcomes separately.
