Questions about Yahoo

We could not reach it (last attempt 13 October 2026). Lines naming yahoo.com stay unchecked until it answers again.
How many apps declare Yahoo in app-ads.txt?
138,992 apps in Stoqlab's data (delisted apps included) declare yahoo.com: 21,518 with at least one DIRECT line and 137,912 with at least one RESELLER line, across 21,326 app-ads.txt files, as of 13 October 2026 (recounted daily).
What is the certification authority ID for Yahoo?
67% of the app-ads.txt lines naming yahoo.com carry "e1a5b5b6e3255540" in the fourth field. The field is optional; the IAB Tech Lab ads.txt 1.1 specification says identifiers in sellers.json supersede it, so a missing or different value does not make a line invalid.
