Hey Marketo Community, we're considering adding a honeypot field to a few of our Marketo forms that are embedded on our website (not Marketo landing pages) - following these steps outlined by Perkuto. (Thanks, Perkuto!).
The honeypot is unlikely to be as useful as you hope -- if you want a more resilient approach search the Nation for "reCAPTCHA."
In any case the honeypot will be no more/less useful with an embedded form.
If your honeypot field is type=text (not type=hidden) then yes, legitimate users with JS disabled would have no way of knowing that you intend to keep the field empty, so you would get false positives. Of course those people also won't have any form validation, either.
Thanks for your response, Sanford Whiteman! Will definitely check out the 'reCAPTCHA' threads.
