Anonymous Leads

According to this doc (Understanding Anonymous Activity and People - Marketo Docs - Product Documentation ):

The first time someone visits a Marketo landing page  (or a page on your website that has the Munchkin Tracking Code), Marketo creates an anonymous lead/activity and uses a browser cookie to track it. Once it's identified, it becomes a KNOWN lead and the history associated with their browser cookie is merged in.

An anonymous lead becomes KNOWN (or merged into an existing lead) when someone:

• Clicks a link in a Marketo email.
• Fills out a Marketo Form.
• Uses Marketo's SOAP or Munchkin API (for developers) to associate an anonymous person with a known record.

Here's some more detailed information around this topic:

Any update on when customers will be migrated to Munchkin v2?

Hi Mark,

An anonymous lead corresponds to a cookie without any personal data in the Marketo database.

You can no longer access them (see Removal of "Is Anonymous" filters. ) in a smart list, but they do not count against your licence quota and they do not appear in the database count.

The only place you can see them in in the "Web Page activity" and in the "company web activity" reports.

Also, they do not grow very old, since Marketo deletes all anonymous that had no web activity in the past 90 days.

The only way to count them is to run a web page activity report and download it.
