Derived from the record
Everything below is computed from the snapshots above. It interprets the record; it is not an observation, and it says nothing about why a system ranked things as it did.
DERIVED Computed from 45 verified snapshots of “home battery backup systems” · US · desktop. Formulas
How much the ranking changed since the previous snapshot: 0 means identical, 100 means nothing in common. It is (1 − rank-biased overlap) × 100, which weights the top positions most.

Labelled from the record
Each result and video below was labelled with the entities it is about, its content type and the intent it serves. These labels are an interpretation, not an observation: they were proposed by deterministic rules (no model), and a person reviewed 0% of them. Entities are kept only when their name appears in the item itself.
RULE-LABELLED 13 items · instructions items-1.0 · labels published 2026-08-14. How labelling works
The share of the top-ten positions held by results or videos about each entity, as labelled. An item about two entities counts for both, so the lines need not add up to 100%.
| Entity | Share of top-ten positions |
|---|---|
| Voltwise | 30% |
| Cellforge | 10% |
| Gridhaven | 10% |
| Amperlane | 10% |
| Fastvolt | 6% |
| Newcell | 4% |
What kind of page or video held the top-ten positions: reviews, lists, news, vendor pages, forums, tutorials and so on, as labelled.
| Content type | Share of top-ten positions |
|---|---|
| review | 30% |
| tutorial | 30% |
| vendor | 20% |
| forum | 10% |
| other | 7% |
| news | 4% |
The intent each top-ten result serves (informational, commercial, transactional or navigational), as labelled.
| Intent | Share of top-ten positions |
|---|---|
| informational | 43% |
| commercial | 40% |
| navigational | 10% |
| transactional | 7% |
Written from computed facts only, never from the raw results; every number in the text appears in a fact it cites. In this demo they are written by rules and published automatically; real narratives are published only after a person approves them.

Select a date to see what was recorded and how it differs from the snapshot before. The analysis is derived from those same files and labelled as such.
The series covers US on desktop. Results were collected by demo-generator on a daily cadence. Read methodology 1.0.
Snapshot index (JSON)Every observation (CSV)
The index lists every snapshot file with its SHA-256 checksum, so a copy can be verified independently. The CSV flattens the same observations, one row per result, with nothing derived added.
