Even though we inform our colleagues, somehow some still fill out a form on someone's behalf or click a link in a forwarded email. I'm thinking about creating a blank landing page that clears the current Marketo cookie on visit (obviously with noindex, nofollow, etc). And then have that secret landing page set as homepage for sales reps and marketers. This way we prevent rogue behavior (page vists, etc) on a lead, whilst it actually was a sales rep accidentely tagged as the lead.
I'm thinking about a few ways of achieving this, but maybe someone already cracked this ;-) Maybe just a simple line of code that sets the date of the Marketo cookie in the past. But then I do need to know how to reference it. Any ideas?
