One of the WordPress plugins that I have been meaning to write about is Comment Referrers by Donncha O Caoimh. Very lightweight, and single purpose, it simply adds a line to e-mails that you receive when new comments are made on a post at your site. If the browser sent a referral URL upon arriving at the page, it is copied in. So if someone has been searching Google for “WordPress Astana ExPat”, I can figure this out if they leave a comment. This can be useful for tailoring your reply to their the visitor’s specific needs, or at the other end of the scale, it is normally very simple to see if someone has simply left a comment to gain a backlink. It also works as a simple way of keeping tabs on which sites or search engines are sending you traffic.
