Where this list came from
The source, and how we filtered it
| Source | IPEDS Institutional Characteristics, HD2024 (directory information), National Center for Education Statistics (NCES) (2024-fall) |
|---|---|
| License | A work of the United States federal government. Not subject to domestic copyright (17 U.S.C. § 105). |
| How we filtered it | Every institution in HD2024 that is active (CYACTIVE 1), degree-granting (DEGGRANT 1) and either takes part in Title IV federal student aid or is a branch of one that does (OPEFLAG 1 or 2): 3,954 institutions in the 50 states, DC and the territories. The address is the institution's own WEBADDR, trimmed and given a scheme. A path on a host only one institution reports is cut back to the site root; a path on a host several report (a chain of campuses on one domain) is kept, because it is what tells the campuses apart. Nothing is dropped for sharing a host: each institution keeps its row and the website is measured once. Rows are ordered by state and name, and carry no rank. See scripts/prepare-higher-ed-roster. |
| Instead of | The US News ranking, a copyrighted compilation we may read but not relicense, which ranks prestige rather than describing the population. |
| 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. |

| #2 · Read
AI generally turns off JavaScript. Does your site information survive without it? |
52% | |
| #3 · Understand
Does a machine know who and what you are? |

| #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 32, the range 1–32, published so that "we sampled 32 URLs per site" cannot become a claim the data does not support.
214 sites in this cohort served a certificate we could not verify. They were read anyway and scored normally, because reporting no response for a site every browser loads would describe our TLS stack rather than the site, and each one carries the finding in its row.
Where this cohort fails

Every site
Every 3,954, 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.
