Can Marketo identify anonymous website visitors?
Learn how Marketo tracks anonymous visitors on your website, its limitations, and what happens when anonymous visitors identify themselves.
How Marketo tracks anonymous visitors
When you implement Marketo's Munchkin tracking code on your website, it begins collecting data on all visitors—even those who haven't identified themselves yet. For anonymous visitors, Marketo:
Say a prospect visits your product pages repeatedly before filling out a form. Once they submit that form—boom—Marketo associates all their previous browsing with their new lead record, revealing their entire journey.
Limitations of anonymous visitor tracking
While Marketo does track anonymous visitors, there are MAJOR limitations:
For instance—you might see an anonymous visitor viewed your landing page, but not which video they watched or which PDF they downloaded.

To access anonymous visitor data in Marketo:
This report shows anonymous page visits with basic location data—but remember, it won't reveal specific interactions.
What happens when anonymous visitors convert
Marketo's real power emerges when anonymous visitors identify themselves. When someone submits a form:
Picture this—an anonymous visitor browses your pricing page multiple times, then fills out a form a week later. Marketo shows their pricing page visits in their lead activity history, giving your sales team crucial context about their interests.
Using web analytics tools alongside Marketo
Since Marketo's anonymous tracking has limitations, use it alongside dedicated analytics:
Use Google Analytics to understand overall traffic patterns and conversion rates, while Marketo shows you which known leads engaged with specific resources.
Practical applications and workarounds
Can't identify specific anonymous visitors? Try these practical approaches:
For a landing page with multiple resources, create a Smart List for each asset to identify known leads who downloaded it, while using Google Analytics to track total downloads—including those anonymous ghosts.
