What wire links actually are
Google has been explicit for years that links in press releases should be nofollow, and the major wires apply that automatically. Syndicated copies are also near-duplicates of one another, so they are not each counted as an independent endorsement.
We say this before you buy rather than after. The value is real but it is reach, indexed brand mentions and citability, not authority. Any agency selling wire distribution as a link-building tactic is selling the one thing it does not do.
