title: Requests from Facebook IPs on Server
body: <p>We are running some ads through Facebook's Ads Manager.</p>
  
  <p>We get requests on our server from Facebook IP addresses that don't show up as clicks in the Ad Manager.</p>
  
  <p>We were wondering if this is due to Facebook rerouting traffic through their servers or if Facebook uses some kind of crawler to test the pages linked to in ads? </p>
  
  <p>For our internal stats, we want to be counting real visits only. </p>
