Substack Programmatically Strips Noindex Tags from Parasite Blogs at an Undocumented Threshold

Substack injects a noindex directive into newly created blogs to gate parasite execution, observes Jesper Nissen.

The platform programmatically strips this tag only after the blog crosses an undocumented trust threshold.

While the specific metric triggers remain undisclosed in the source, crossing this threshold forces search visibility.

A test article targeting "entity stacking SEO" successfully dropped the tag and ranked at the top of page two.

However, this indexation state remains volatile; the platform may re-apply the noindex directive, dropping URLs back out of the index without warning.
