The file
Amplitude publishes an llms.txt at https://amplitude.com/llms.txt.
The file declares itself as Amplitude in its H1, and the host is categorised here as SaaS. It was last fetched and parsed on 12 October 2026.
Measured structure
| Measure | Amplitude | Corpus median | Percentile |
|---|---|---|---|
| Size | 14.0 KB | 14.0 KB | 49% |
| H2 sections | 5 | 8 | 34% |
| Links | 16 | 71 | 18% |
| Blockquote summary | Absent | 107 of 125 have one | n/a |
Percentiles are against the 125 files in this directory, not against the web. That population is deliberately weighted toward documentation platforms and developer tools, which is where the convention started, so treat it as a peer group rather than a norm.
Observations
- No blockquote summary was detected. The proposal allows an optional summary after H1; only H1 is required. The same absence occurs in 18 of the 125 directory files.
- The file contains 16 list links, below the corpus median of 71. A short list can make navigation easier, but the count alone does not establish the relevance of its links.

How this was measured
The historical check followed redirects, rejected HTML responses and required an initial H1. It counted H2 headings and Markdown list links with regular expressions, rather than running the full validator. Counts and bytes describe the retained response text, subject to the extraction limit. This snapshot was generated on 2026-10-12.
