Google’s John Mueller said on Twitter that when you merge or split a site, it is “essentially creating a new site.” So that might mean, that if it is a substantial enough site merge or split, that Google may decide to treat the site as a brand new one and maybe some of the legacy signals might not carry over?
Here is what John said:
Merging or splitting sites doesn’t result in something you can exactly determine ahead of time. You’re essentially creating a new site.
