Marketo Landing Page Preview URL
Marketo has this very underrated but very practical feature for generating a short-lived preview URL for landing pages that could be accessed by the open world (i.e., people could preview the LP without even having access to Marketo).
Marketers could generate this short-lived preview URL by going to the respective landing page in Marketo > Landing Page Actions dropdown > URL Tools > Generate Preview URL.
The preview URL remains good for 8 hours from the time it is generated and renders the draft version of the LP if it exists. Moreover, any updates to the draft version are also reflected in real-time via this preview URL.
It could be just me, but I feel that not a lot of marketers know about this very practical option available in Marketo, and again, IRL, not a lot of them may need to get a sign-off from people who aren't Marketo users before approving a landing page. However, if ever need be, there's always an option to generate a temporary preview URL and share it with the folks without having to add them as the user(s) in Marketo.
