I've said this for years, and I think every digital evangelist wakes up in cold sweats every night thinking about it. ROI in the digital space (SEM, social media, e-commerce, campaign sites, email marketing, etc.) is measurable, accurate and accountable. You know your digital ROI for every dollar spent, but if you're spending offline, you really have no idea what you're getting. I've seen the equations that publications use to guess their reach and it's total BS. I've also heard radio DJs exclaim that they really have no idea how many people are listening.
I can say this all day long, but I think Gary Vaynerchuk (who I met at Blog World Expo and is even more fantastic in person) does it with his unique passion, so here you go. Enjoy, and if you don't follow Gary's blog and watch his videos please make it a point to do so.
Are you moving more dollars online? Are you seeing more pressure put on magazines, newspapers, radio and TV to deliver? What are you having success in measuring for clients?
I'd love to know what you think.
