@peterjohn12345 This tool allows you to indicate to Google which links you would like to disavow, and Google will typically ignore those links. Much like with rel=”canonical”, this is a strong suggestion rather than a directive—Google reserves the right to trust our own judgment for corner cases, for example—but we will typically use that indication from you when we assess links.
