Some visitors are not getting logged

Here are some common reasons why a visitor may not show up in your visitor log:

  • The visitor is using an ad-blocker. Most ad-blockers also block trackers, and approximately 15% of internet users have one installed, so this is very common. Consider using our proxy tracking feature to block the ad-blockers and log everyone!

  • The visitor is you! We automatically filter out your own visits to your websites.

  • They are an evil bot, typically of the spam referrer variety. These are bots whose sole purpose is to leave spammy referrers in your logs that you then click and visit their terrible site. We aggressively filters these. When customers notify us of new ones, we add them to our blacklist immediately. As far as we know, no other service blocks spam like we do. See here and here for more info on malicious bots. (These kind of bots cannot be un-blocked).

  • They are a friendly bot (crawler, etc). These get blocked by default too, but there is an option to log friendly bots.

  • Your site may be using a Referrer Policy header that blocks the referrer, or a Content Security Policy (CSP) header that blocks our code from executing. More info and the correct settings to use are on this page.

  • They are on a VPN that proxies through a data center such as Amazon Web Services. We filter out visitors from data center IPs as much as possible because they are usually bots.

  • Their firewall blocked our domain or tracking servers

  • Their browser is not sending a proper referrer, breaking our domain validation system

  • They have a slow connection and didn't have time to download and execute our tracking code before moving on

  • They have disabled Javascript, and your site doesn't have the "noscript" code installed

  • They matched one of your IP address or other kinds of filters, and hence were intentionally not logged

  • Your visitor privacy settings may have impacted this visitor in your reports:
    • Their IP address was anonymized so you didn't recognize them; OR...
    • They were ignored completely because of global Opt Out cookie.
