Some organizations are using bots to pre-screen incoming emails by clicking on all links prior to allowing users to have access to them. This appears to be resulting in a boost in the total clicks that emails appear to be getting – these additional clicks can be considered to be “false positives” because they are not a human that is clicking.
To test if there is bot activity add a small 1-pixel transparent image to the ClickDimensions email template which links to this page.
It’s nearly impossible that any click to this page would be made by a human, so it’s probably an email spam filter ‘checking’ the links. Any other clicks attributed to that person are going to be unreliable.
