Now that advertisers are starting to spend real money on Twitter, the pressure is on to prove that those investments deliver tangible results. Twitter took a step in that direction today by announcing its partnership with the data giant Datalogix to gauge the impact of tweets — both paid and organic — on sales for consumer packaged goods marketers.
Datalogix and Twitter find the correlation between tweets and purchases by matching email addresses that have been scrambled — or “hashed” — to ensure users’ anonymity. Twitter users provide an email address when registering their account, and Datalogix collects emails through loyalty programs. (Datalogix has a similar deal with Facebook to connect users and their purchases.)
