Over the past couple months we've noticed several instances where new leads show the Visit Web Page activity hours before Marketo registers the New Person and Fill Out Form activities. The visitors only would've made it to a confirmation page after filling out a form, so the form data should be available almost immediately.
Marketo Support suggested creating a Smart Campaign with the Visits Webpage trigger and the Not Filled Out Form filter in order to alert our team, however these leads are still anonymous to us until the New Person and Fill Out Form activities are processed.
Support also let us know that these occurrences correlated with lag times across the datacenter, so there's nothing we can do within our instance to prevent this from happening in the future.
At this point we're hoping for two things: 1.) A way for our team to be alerted when lags like this occur (none of these occurrences led to updates on Marketo's Status Page), and 2.) A way to capture the form data so our sales team doesn't have to potentially wait hours before the lead is known and synced to SFDC.
Has anyone run into a similar problem in the past, and do you have any suggestions for staying on top of this issue?
