I want to say , thank you super much !! I tried to search the answers on online and viewed hundreds of pieces of content but could not find the answers. However, what you replied made me clearer and I am really excited to figure it out.
Allow me to ask more questions to truly understand. Sorry I am not a technical guy so I have to try to use my way to explain and understand. If I tried to research the logic of each cookie, it's gonna to have more and more questions….
It depends on how the lead comes to your website.
If the lead follows a tracked link in a Marketo email (links are tracked by default), the link will include a special unique mkt_tok query parameter. If Munchkin, Marketo's analytics module, is running on your website, then the mkt_tok will be used to associate the Munchkin cookie with the lead in your database. Both previous and subsequent web activities will then be found in the lead's Activity Log.
→If Y sir are in our Marketo ( we imported him to the Marketo a while ago), afterwards, when he clicked our email sent by Marketo, "the mkt_tok will include his email address" and when his visit our website embedded with Munchkin code, we used the "email address" to map the leads in our database. Can I think like this ? I am not able to totally understand the relationships between mkt_tok , Munchkin cookie, and lead in our database. Could you elaborate on this more ?
one more question: How about filling out a form, If Y sir fills out a form the website with Munchin code, can we associate him with his web visit behavior ?
If the link is not tracked, but it has been specially constructed (again inside Marketo, via Velocity token or other special URL construction) to attach the same unique mkt_tok query param, then the cookie will also be associated
→I think if I can understand how above logic works, then I can understand what you mean here. It's like we use mkt_tok parameter to make Munchkin cookie associate the leads in our database. Should the link must be something like email ? Is it possible we can identity a web visit via a social media post with the link append mkt_tok ?
If the person merely arrives on your page, but doesn't identify themselves via form fillout nor have that very special mkt_tok, then Munchkin would have no way of knowing who they are — so the session remains anonymous.
The second scenario is when visitor first time enter our website and Marketo will create an anonymous activity and when this visitor fill out a Marketo form. This visitor would be merged to a known person in Marketo. I want to know how Marketo identify it? Is it done by sourcing the IP address to match between web visit and form info.
The IP address is never used. Remember, tens of thousands of people can share the same IP address!
The Munchkin tracking cookie (_mkto_trk) is used to maintain the anonymous session. Whenever someone fills out a Marketo form, the value cookie is automatically posted to Marketo in a hidden field. This allows Marketo to associate formerly anonymous activities with the new or existing lead identified by Email Address.
→Sorry I don’t know this. If a visitor fills out a form, there is a value cookie generated and Marketo can associate that value cookie with the mkto_trk generated by anonymous session. However, when a person visits the website, how Marketo know which email address does he use, is he source a person’s email address by other platform he logged in before ?
