Data Freshness Dashboard

Transparent data quality metrics. We track 1,574 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

45 records have failed 3 re-checks in a row, so they are retried every 7 days instead of every day. 14 where we could not connect, 11 where our checker was refused, 10 where the page is gone, 9 where our reader could not decide, 1 where the page we cite is not about this offer. 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.
