How many websites can Marketo track with one instance

[Anonymous]

If our company owns many domains, and we install the same munchkin across all those sites, will Marketo track visits properly?

If not, what is best practice?

Yes, you can do this. The caveat is the lead will be tracked separately on EACH site (as a separate Lead ID) until the lead fills out a form on each site with the same email address.

This is because we have only first party cookies- meaning they can only be read by sites in the same domain as the one that wrote them. Many customers have multiple sites though, and particularly if leads really aren't going to hit all sites, it works fine.
