Data Freshness Dashboard

Transparent data quality metrics. We track 1,498 offers — here’s what we can and cannot source for them.

Confirmed counts the entries whose terms we can source to a read that confirmed them. Catalogue date counts the catalogue date beside the entry, which records when it was last written and is not a confirmation.

Confirmation Coverage by Category

60 categories ranked by confirmation coverage — the share of a category’s entries whose terms we can source to a read that confirmed them within 90 days. The second column is the catalogue date over the same window, which is not a confirmation, and the two are far apart.

Stalest Entries

Top 20 entries most in need of re-verification, ordered by the age of the catalogue date.

Records we cannot currently check

99 records have failed 3 re-checks in a row, so they are retried every 7 days instead of every day. 25 where the page rendered nothing we could read, 24 where our reader could not decide, 15 where we could not connect, 14 where the page we cite is not about this offer, 12 where our checker was refused, 7 where the page is gone, 2 where the request timed out. A failure here is usually our checker being refused or reading the wrong page — it is not evidence that the vendor changed anything. Last confirmed reads the same store as the coverage figure above, so a row saying never is a record counted outside that figure.

Newest Catalogue Dates

Top 20 entries by the age of the catalogue date. A recent date here says the entry was written recently, not that we confirmed it — the Confirmed column says that.
