How many job postings tell us when they were published

Listing age is one of the few things you can measure from a job ad without asking anyone. But you can only measure it for postings that carry a publication date. This page shows, platform by platform, how often that date is available in our index — and how much of what looks like ‘fresh listings’ is really missing or crawl-linked dates.

Frequently asked

What does ‘publication date missing’ mean?

7.17% of the postings in this snapshot arrive without a publication date. We keep the posting, but it cannot enter any age or staleness measure.

How are the stale shares calculated?

Age is computed only for postings that carry a valid publication date, so every stale share uses the dated postings as its denominator. Undated postings are counted separately and are never mixed into an age statistic.

Why is the stated date sometimes later than our crawl?

Some platforms report a date later than the day our crawler last saw the posting. We report what the source says; that ordering is not evidence of a future publication date.

Does a missing date mean the platform is at fault?

No. This measures availability and consistency in our own crawl record, not platform quality. A missing date may be how a source presents dates, how we capture them, or a mix.

Is the reported date the true original publication date?

No. It is the date the source reports. We do not adjust or reinterpret it.

Is this a census of all job postings?

No. It is our crawl corpus, measured on one weekly snapshot — not a daily measurement and not a census of the whole internet.

More data

‘Publication date missing’ counts postings in the 2026-09-20 weekly snapshot whose source record carries no usable date. Stale shares use only dated postings as the denominator. ‘pub’ is the date the source reports; ‘seen’ is when our crawler last saw the posting. 1 smaller platforms (fewer than 500 postings each) are not shown. This page is not a census and is not a claim about platform quality. Page generated 2026-09-21.
