 ## Sources
 
 In the "**Sources**" tab within the "**Top Sources**" report, you can see the full list of your referral sources such as "**Google**", "**Facebook**", "**LinkedIn**", "**Reddit**" and "**chatgpt.com**".
 
 Note that browsers only send the domain name of the referrer and not the actual URL. If `thatblog.com/one-post/` sends you visitors, you will see `thatblog.com` in your sources list but won’t see the exact post URL itself. [See more here](https://plausible.io/blog/referrer-policy).
