Research changelog: every update and correction

The Postdom research changelog lists every update and correction to Postdom research, newest first, so you can see what changed, on which page and when.

On 10 October 2026 Postdom corrected its TikTok saves headline to compare tutorials with all 656 videos (41 against 11 saves per 100 likes) instead of a group of 24 funny videos.

Definition. An update adds new data; a correction changes a published claim; a page change alters names, layout or licensing without new data.

Last updated 10 October 2026. Next update: 24 October 2026, with the Postdom AI Content Index pilot (target). Data lead: Ana Ibáñez Lario.
