Anonymous Browse Tracking is enabled feature on the Enterprise License.
This feature stores browse tracking from your website for anonymous users up to 30 days and makes that tracking data available once the user signs up for your mailing list to give you a more well-rounded view of your new subscribers' interests as well as what pages on your site led to the conversion.
How Does It Work?
(Notes on the code: There is a separate code for purchase tracking specifically for cart pages, etc. Within this code you can also "tag" your pages to categorize them for later use. For example when adjusting Lead Score to include browsed data you can say browsed "Living Room Furniture" pages rather than inserting all specific URLs).
Where Can I Use It?
Anonymous Browse Tracking can be used to increase personalization in segments, automation, and lead scoring. It is viewable in Clickstream reports and on individual contact records.
