I want to share the unreviewed version of my future website with a few people on an URL like this:
example.com/hidden-unreviewed-version
I would apply noindex on it and all its subpages to hide them from search engines. Later, the final version would be moved to the root of the same domain without noindex. Until then, the hidden subpages would be the only worthwhile content on the domain.
Will the noindex contaminate the whole domain for a long time, or do search engines consider the whole url of the page to be ignored? The former hardly seems logical, but I want to be sure to avoid the risk.
(P.S. I found a related answer, but that is about Google's URL removal tool, and not explicitly noindex, so my doubts were not dissipated.)
