# Podcast links on the homepages of four company lists

Two kinds of row, marked by `row_type`. A `metric` row carries one aggregate
with the base it was computed on. A `domain` row carries one company whose
homepage carried a podcast signal.

## Columns

- `row_type`: `metric` or `domain`.
- `group`: `inc5000_2026`, `yc`, `fortune500`, `unicorns` or
  `all four groups`.
- `segment`: `all` for a whole-group figure, otherwise the cut and the
  segment, such as `industry: Consumer Products`, `batch year block: 2022` or
  `rank band: 1-100`. Empty on domain rows.
- `metric`: on a metric row, the figure. `base` is the number of companies
  counted. `p1_podcast_link_count`, `p2_podcast_path_count`,
  `p3_podcast_embed_count` and `podcast_any_count` are domain counts, and the
  matching `_pct` metrics are those counts as a percentage of `base`.
  `p1_platform_<name>` counts the domains whose P1 link points at that
  platform. `truncated_records_count` counts the pages that hit the storage
  cap. Empty on domain rows.
- `value`: the figure. A count of one to four prints `<5`; a share on a base
  under 20 prints `n/a`.
- `base`: the denominator for that row.
- `domain`, `name`: the company, on domain rows.
- `rank`: Fortune 500 rank, on Fortune 500 domain rows.
- `industry`: Inc 5000 industry, on Inc 5000 domain rows.
- `batch`: Y Combinator batch year, on YC domain rows.
- `p1_platforms`: the podcast platforms the homepage links, pipe separated.
- `p1_url`: the first platform link found.
- `p2_href`: the first same-site podcast link found.
- `p3_platforms`: the player embeds or podcast RSS links found.
- `verdict`: `true` for the Fortune 500 domain rows, every one of which was
  opened in the archived HTML and judged by hand. Empty for the other three
  groups, which were not hand checked one by one.
- `show_name`: the podcast the anchor names, where the homepage names one.
  Empty where the homepage links only a podcast hub.

## Denominators

The base for every percentage is the companies in that group with a usable
archived homepage: an HTTP status under 400 and a non-empty body.

| Group | Base | Domains on the list |
| --- | ---: | ---: |
| Inc 5000 (2026) | 4,885 | 4,969 |
| Y Combinator | 5,386 | 6,133 |
| Fortune 500 | 472 | 500 |
| Unicorns | 1,000 | 1,111 |
| All four | 11,743 | 12,713 |
