Enhancing Bot Filtering Functionality in Marketo

Marketo filters bot clicks based on IAB lists (known registry of non-human traffic sources/bots) or by identifying proximity patterns (multiple clicks within a short timeframe). However, bot activity has evolved leading to several bot engagements slipping through the cracks and firing off triggered smart campaigns that track link clicks. We recently identified two bot click behaviors we would like the development team at Marketo to investigate and patch:

  1.  Logged clicks on links before “Email is Delivered” logging
  2. Click proximity outside the configurable 0-3 second window but within 30 seconds of email delivery

I am sure multiple Marketo Admins have dealt with false positive click engagements and have had to answer to their teams. This submitted idea within the Idea Portal is to alert the Adobe Marketo Engage development team of the need to tighten up criteria relating to bot click activity.

Many modern email security tools (Microsoft Safe Links, Proofpoint, Mimecast, Barracuda, etc.) now perform delayed link scanning, which can fall outside that proximity window. That’s why you sometimes see clicks very shortly after the send or even before/around the same time as email is delivered. Having said that, Bot email filtering/scanning could never get 100% accurate as security scanners are constantly evolving specifically to behave like real users, which makes it difficult for platforms like Marketo to reliably distinguish them from genuine engagement.
