Where this list came from
The source, and how we filtered it
| Source | Current members of Congress (legislators-current), The @unitedstates project (unitedstates/congress-legislators) (2026-10-11) |
|---|---|
| License | Dedicated to the public domain by its contributors under CC0 1.0 Universal. The facts in it are the members' own and the House's and Senate's, works of the United States federal government. |
| How we filtered it | Every record in legislators-current.json, which is 100 senators, the sitting voting representatives and the six non-voting members (the delegates for DC, American Samoa, Guam, the Northern Mariana Islands and the Virgin Islands, and Puerto Rico's Resident Commissioner). The address is the `url` of the member's current term, which is the member's official website; it is never a campaign site. A House seat with no sitting member is left out and named in the cohort's description, found by comparing the roster with each state's 2020-apportionment seat count. |
| Instead of | The Congress.gov Member API, which is authoritative but needs a key and carries no official-website field for most members. |
| Built | 2026-10-11 |
The filtering is ours and is disclosed as ours. The source published a list; the decision about which rows of it belong in a cohort was a judgment call, and it is written down so somebody can disagree with it.

By dimension
What the cohort earns, dimension by dimension
The mean share of each dimension’s available points that this cohort earned. Low here means the whole sector is weak on it, not that one site dragged an average down. The per-site spread is in the dataset.
| Dimension | Mean share earned | Mean |
|---|---|---|
| #1 · Reach
These parameters determine the fundamental ease of access that AI has to your site information. |
44% | |
| #2 · Read
AI generally turns off JavaScript. Does your site information survive without it? |
17% | |
| #3 · Understand
Does a machine know who and what you are? |
19% | |
| #4 · Act
Sitemaps, redirects, 404s, licensing terms, and not wasting the crawl budget. |

How much of each site we read
The cap is 32 URLs and it is a ceiling, not a promise. A portal whose every link points at a different host yields one page; a university yields the full sample. The median here is 1, the range 1–1, published so that "we sampled 32 URLs per site" cannot become a claim the data does not support.

Every site
Every 539, named, with a report for each
Whether or not it has been scanned. Rows with no website on record, sites that were unreachable and sites that turned us away stay in the table with the reason on them, and none of them enters an average: dropping them would shrink the population to the part that was easy to measure. A few points between two neighbors is noise. The box filters every row in the cohort, not only the page you are on; click a header to sort the rows on this page by name or by score.
