What is a website acceptor in SEO?

Site acceptor – SEO WIKI

An acceptor is a website that is linked to from another site (donor). This link gives the reference weight.

The donor-acceptor scheme works like this. A certain weight, which, due to a number of factors, has a different value, is transmitted via an external link. By clicking on it, the user gets from the donor to the acceptor site, which distributes the received weight among the internal pages of the resource or, if external linking is configured, transfers it to other sites. Any acceptor site can be a donor site at the same time.
