Citation history

Cited runs month by month

probioticscience.org was first cited in a monitored answer run on November 4, 2026, in this release's latest month. The release window opens 2026-05-10, so an earlier citation would not show here.

A month's rate is the share of all monitored answer runs that month that cited this domain. The latest month is still collecting.

Month	Cited runs	Observed runs	Rate
November 2026 (to November 10, 2026)	2	3,662	0.05%

By answer engine

Which engines cite probioticscience.org

An engine's rate is its cited runs over every monitored run that engine answered in the window. Engines answer different numbers of runs, so compare rates, not counts.

Engine	Cited runs	Engine’s observed runs	Rate
Claude	2	9,086	0.02%
ChatGPT	0	9,046	0.00%
Gemini	0	7,316	0.00%

The public dataset reports citation rates, rankings, and evidence counts. It excludes internal query identifiers, raw cited URLs, and answer-engine provider payloads. MRI measures observed root-domain citations in monitored prompts, not all AI answers, recommendation quality, web traffic or commercial performance. A citation is not source support.
