How sourced are the answers?

Citations per response over the last 12 complete weeks: whether the models are leaning on the web more or less.

Figure 2Citations per answer, week by week

Each cell is one model in one week; hotter cells mean answers leaned on more sources. Single-hue ramp; the scale runs from the lowest to the highest cell shown.

Methodology

What's counted: every citation/source URL Gemini returned across the rolling 4 ISO weeks, aggregated from every analysis run on BrandInsightAI. Citations deduplicate to one registrable domain per model response.
Quality gate: a domain must appear across ≥ 2 distinct projects to be named; shares are computed against ALL citations in scope, so the gate hides names, never distorts percentages.
Movers: week-over-week comparisons use the two most recent COMPLETE ISO weeks (2026-08-31 → 2026-09-07); the in-progress week is excluded because it refreshes hourly, and a domain must clear the citation floor in BOTH weeks, so a newly monitored category entering the dataset never shows up as a gainer.
Freshness: the snapshot behind this page recomputes every hour. All figures are measured, never estimated.
