Where this list came from
The source, and how we filtered it
| Source | SEC company tickers by exchange, with EDGAR submissions (SIC code, website) and, for the S&P 500 flag, the Wikipedia constituent list, US Securities and Exchange Commission (SEC), with Wikidata and Wikipedia (2026-10-11) |
|---|---|
| License | SEC filings and the SEC's published data files are a work of the United States federal government and carry no domestic copyright (17 U.S.C. § 105). Web addresses found nowhere on EDGAR come from Wikidata (CC0) or from our own crawl of the S&P 500 list, disclosed per row. Membership of the S&P 500 comes from Wikipedia's constituent list, CC BY-SA 4.0, the same license this cohort goes out under; “S&P 500” is a registered trademark of S&P Dow Jones Indices LLC, naming the constituents is descriptive use, and nothing here is endorsed by or affiliated with S&P. |
| How we filtered it | Every CIK the SEC lists with a security on Nasdaq, NYSE, CBOE or TXSE (OTC and unlisted entries are not listed securities and are left out), read against its EDGAR submissions record for the SIC code, the company's own website and its tickers. Excluded as not operating companies: SIC 6221 (commodity pools and trusts), 6726 (unit investment trusts and investment vehicles), 6189 (asset-backed issuers), 6770 (blank-check shells), registrants with no SIC code (ETFs and grantor trusts) and registrants whose name says fund or exchange-traded product. A company with several share classes is one row. The web address is EDGAR's own `website` where it has one; else the address found by crawling for the S&P 500 list; else Wikidata's official website (P856) for the entity whose SEC CIK property (P5531) matches; else the row stays with a note. Each row says which. The vertical of each row is its SIC code's, through one table with ticker overrides (ten7_air/census/build_public_companies.py). Companies that share a website are all kept and measured once. The roster is as of the build date, and rows are in CIK order because the SEC data carries no measure of size to rank by. See scripts/prepare_public_companies.py. |
| Instead of | The S&P 500 alone, which this replaces: a list of 500 chosen by a committee, where the SEC's is every listed company and the 500 stay identifiable inside it. |
| 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. |
72% | |
| #2 · Read
AI generally turns off JavaScript. Does your site information survive without it? |
45% | |
| #3 · Understand
Does a machine know who and what you are? |
29% | |
| #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.
51 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.

Every site
Every 5,239, 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.
