Plenty of people talk about “social media engagement” and “engagement” may be the most overused platitude in the world of social media marketing.

Marketers are constantly looking to prove the ROI of social, and if you’re going to start somewhere, you’ve got to start measuring. Dan Zarrella, the Principal Social Media Scientist at Hubspot, is a leader in this space.

Dan digs into the numbers, millions of numbers, to find the answer to questions like, “When’s the best time of day to post to Facebook?” If you follow social media experts on Twitter, you’ve probably seen his work already, because his studies always get attention when he releases a new set of data.

Dan joined us on Media Masters to talk about his work measuring social media, and offered his top tricks and techniques for social media success. And he’s got the data to back up his claims.
