For pages first cited during the month by a provider that had verifiably crawled them earlier, the median number of days between that first crawl and that first citation. It measures a sequence on our own pages, not a cause.

Covers: 2026-08 — 2026-08
Method: Pairs are formed per provider and per path: the first verified crawl of the path and the first citation of the same path by the same provider. The month is the month of the citation. Paths are compared without query or fragment.
Method version: 1.0
Last point added: 2026-09-21

Series

| Month | Median lag | Pages first cited | Point added | | --- | --- | --- | --- | | 2026-08 | 11 days | 24 | 2026-09-21 |

Only closed months appear. A month is added once, after it ends, and is never recomputed afterwards; the "point added" column records when. The series starts in the first month with at least one such pair; every month in it is complete.

How to read it

Samples are small, because citations of our own pages are rare, and one provider accounts for most of them. The sample size is printed with every point for that reason.

Method

Pairs are formed per provider and per path: the first verified crawl of the path and the first citation of the same path by the same provider. The month is the month of the citation. Paths are compared without query or fragment. Method version 1.0. If the method changes, the version changes and this page states from which month the new version applies; earlier points keep the method they were computed with.
