Confirmed: Quantcast joins NAI + comments on the good, the bad and the interesting

June 22, 2009

As mentioned here several weeks ago, Quantcast, which collects user information across thousands of sites, has officially joined the Network Advertising Initiative.

The relevant changes to the Quantcast privacy policy follow below. Here are some quick observations:

  1. Interesting: The Quantcast opt-out only applies to their advertising delivery services. They do not allow consumers to opt out of tracking for the purposes of audience measurement.
  2. Good: The policy confirms that Quantcast uses Flash cookies, and states that those are only used for audience measurement of Flash applications and not for behavioral ad targeting. There is no Flash cookie opt-out provided, which aligns with their theory that no opt-out is necessary for audience measurement.
  3. Good: They have a direct link to their opt-out on their top page. Not prominent, but it is there at least.
  4. Good: They now have a deletion policy (called for by the privacychoice best practices for opt-outs). Log data is retained indefinitely for audience research and 13 months for advertising purposes, which puts them among the companies with shorter retention periods (at least for advertising).
  5. Good and Bad: They fixed the issues I mentioned with their prior implementation (unique cookie value), and now have a straightforward, non-unique opt-out cookie. However, they assign a cookie deletion date/time based on the date/time when first set, which — doh! — means the cookie is no longer non-unique.
  6. Not so good: The policy does not expressly state that if you opt-out, behavioral information will not be collected and shared; it only says that if you opt out you will not receive interest-based advertising and content.  A better practice would be to make it clear no information is collected from opted-out users for any purpose other than audience measurement.
