RE: Issue-39: Tracking of Geographic Data

Cross site – don’t label an IP address as likely to be home address vs
likely to be work address, based on past logging of the IP at different
times/locations.

 

Real time/single site – do recognize user is coming from IP address
belonging to a company/during the day – likely to be at work.  (Staples ad
prioritized over ad for movie trailer)

Aleecia,

 

The geo-location discussion was on the first day and fairly early in the
event.  I believe the conversation has progressed significantly and as we
narrow in on the “cross-site” element of “tracking” I’m struggling to see
how geo-location fits into the “cross-site” model.  If the group feels that
IP Address derived geo-location should not be used across sessions if the
user has DNT activated, that makes sense to me but I’m not sure if geo
granularity is important in this context (any geo vs. Zip4).

Reminder: we had a fairly lengthy discussion about geoIP in the context of
how identifying zip plus 4 is (about 12 households) and had a general sense
that it is hard to claim there is no tracking if you can identify location
that closely. I can pull the call minutes and/or prior email threads where
Shane argues against zip plus 4 being ok if that is helpful context.

Is it perhaps the concept of across sites, over time? I think this is what
Jeff is getting at too, when he talks about multiple data sources.

If ad network just uses the IP address that accompanies HTTP request to
provide relevant content or ads, OK. If ad network remembers it in a profile
it retain about you based on cross site activity, that is not OK, when DNT
signal is sent (absent some other exception).

Yes?

nope. not what I meant. I'm trying to find a better way 
to express the cross-data aggregation around IP geolocation.
