## Observed Segments

| Category | Question shape | State | Cited runs | Observed runs | Run dates | Rate | Standing |
|---|---|---|---:|---:|---:|---:|---|
| [Consumer Health](https://machinerelations.ai/index/categories/consumer-health) | [Is it worth it](https://machinerelations.ai/index/categories/consumer-health/is_x_worth) | published | 2 | 302 | 13 | 0.66% | #157 of 309 |

## Citation History

nutritionheartbeat.com was first cited in a monitored answer run on October 20, 2026, and most recently on November 4, 2026, with cited runs in each of the 2 months from then to this release. 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 |
|---|---:|---:|---:|
| October 2026 | 1 | 16,496 | 0.01% |
| November 2026 (to 2026-11-11) | 1 | 3,966 | 0.03% |

## By Answer Engine

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 |
|---|---:|---:|---:|
| [Google AI Overviews](https://machinerelations.ai/index/engines/google_ai_overviews) | 2 | 1,354 | 0.15% |
| [ChatGPT](https://machinerelations.ai/index/engines/chatgpt) | 0 | 9,137 | 0.00% |
| [Claude](https://machinerelations.ai/index/engines/claude) | 0 | 9,177 | 0.00% |
| [Gemini](https://machinerelations.ai/index/engines/gemini) | 0 | 7,326 | 0.00% |
| [Google AI Mode](https://machinerelations.ai/index/engines/google_ai_mode) | 0 | 2,198 | 0.00% |
| [Perplexity](https://machinerelations.ai/index/engines/perplexity) | 0 | 9,257 | 0.00% |

Since August 31, 2026, nutritionheartbeat.com is cited in none of 992 observed Google AI Mode runs. Google AI Mode's collection changed between August 10, 2026 and August 30, 2026, so its row above pools both sides of the change.

Since October 7, 2026, nutritionheartbeat.com is cited in none of 4,488 observed Perplexity runs. Perplexity's collection changed between October 6, 2026 and October 7, 2026, so its row above pools both sides of the change.

## Public Boundary

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; it does not measure all AI answers, recommendation quality, website traffic, or commercial performance. A citation does not prove source support, and MRI confidence is not an Answer-Source Fidelity grade.
