status_code

Optional

HTTP status code of the homepage fetch

Type:integer | null

Example:200

sitemap_url

Optional

URL of the sitemap that produced the sitemap_lastmod signal (or the first sitemap we could reach, when lastmod extraction failed)

Type:string | null

Example:https://www.example.com/sitemap.xml

sitemap_lastmod

Optional

Max across all URLs in the sitemap. When the top-level file is a sitemap-index, we recurse one level (up to 3 child sitemaps) and take the max across those.

Type:string | null

Example:2024-11-14

homepage_last_modified

Optional

Value of the Last-Modified HTTP header on the homepage response, parsed to a UTC date

Type:string | null

Example:2024-11-14

footer_copyright_year

Optional

Highest 4-digit year found near a copyright anchor in the last 4000 bytes of the homepage HTML. Weakest signal -- nearly every CMS auto-renders the current year, so this is treated as the pessimistic Jan-01 of the year and outranked by every other signal.

Type:integer | null

Example:2024

latest_feed_pubdate

Optional

Most recent / across the site's RSS or Atom feeds. Feeds are discovered from tags on the homepage plus well-known paths (/feed, /rss, /atom.xml).

Type:string | null

Example:2024-11-01

most_recent_signal

Optional

Date of the winning signal after source-precedence resolution. Precedence: sitemap > homepage_header > feed > footer. Stronger sources beat weaker ones even when their date is older.

Type:string | null

Example:2024-11-14

most_recent_source

Optional

Which signal produced most_recent_signal (winner of the source-precedence + newest-date resolution)

Type:string | null

Example:sitemap

Options:

sitemaphomepage_headerfooterfeed

stale_flag

Optional

Verdict against most_recent_signal. active = <6 months. stale = 6-18 months. abandoned = >18 months. unknown = no signal, or only footer_copyright_year was available (see signal_note).

Type:string | null

Example:active

Options:

activestaleabandonedunknown

months_since_last_signal

Optional

Age of most_recent_signal in months (approximation using a 30.4375-day month). Null when stale_flag is unknown.

Type:number | null

Example:3.2

signals_found

Optional

Count of the four freshness signals that produced a usable date (0-4)

Type:integer | null

Example:4

signal_note

Optional

Explanatory note for edge cases (e.g. only a footer copyright year could be extracted). Empty when the verdict is confident.

Type:string | null

Example:only footer_copyright_year available -- freshness inconclusive

probed_at

Optional

ISO timestamp of the probe

Type:string | null

Example:2026-07-21T09:00:00Z

error
