Google’s John Mueller said on Twitter that Google Search does not count links on a domain level. John is basically saying that each link counts for itself and that each URL counts for itself, the links don’t add up to some overall authority metric that Google might use on the domain level.

This is not new, Google has said it does not have overall domain authority as a concept, that it doesn’t have website authority concepts, but Google does use sitewide signals for new URLs and for other purposes.
