Refback is a linkback method that works using the standard HTTP Referer header. Like pingbacks, trackbacks, and webmentions, it attempts to present links of other sites that have linked to you. Unlike other methods, the other site requires no additional support. The implementation works exactly as the other linkbacks do in WordPress.
