The referrer log admin page contains a list of all referrers coming from other websites for the past seven days. Whenever another website has a hyperlink pointing to your blog and someone follows it, the referring page will get listed. That way you can keep
track of who links to you.
The log only keeps records of the last seven days to avoid using too much disk space. If you want a more detailed referral analysis, it is recommended that you use third-party tools such as Google Analytics or StatCounter.
Enable the log
By default, the referrer log is turned off. You turn it on by checking the checkbox in the top of the Referrers admin page. After it has been turned on, it doesn’t show any data. That is because no referrer data has been collected yet, but after a little while
(depending on the popularity of your blog) the referrers start to appear on the list.
