Feeling silly for not being able to figure this one out.
What's the best way to identify which forms are being used and how frequently?
Sure, the Bulk Extract docs.
Unfortunately, there is no out-of-the-box "form performance" report to provide this information, but you can vote for the idea here: Form conversion report to include both Marketo LP forms and embedded forms
The only other solution I can think of is creating smart lists for "filled out form: Form 1" and the resulting people will give you an idea of how many people filled it out.
Depends on what you mean by "used". Some take that to mean how often an embedded form is rendered, not how many times it is filled out. This takes some JS to set up Munchkin-based logging of the render event.
If you mean filled out then you can do a relatively simple Activity Log extract via API that shows only Filled Out Form activities. However, this exercise is not code-free.
Sanford Whiteman very inciteful. Any previous articles or places to direct me on the the "non code-free" work to be done to get this activity log extract?
