Hello Taylor,
Apologies that this has been a source of frustration for you. I dug
around a bit on my end and determined that the team responsible for
providing traffic estimate data is aware of a change that effectively
ignores proximity target data that you pass in to the service. If your
request only contains proximity targets, then you'll get back the same
estimate you would when no geo targeting is specified.
Unfortunately, this is not functionality that they are able to add
back, and my understanding is that the web based version of the
traffic estimator (
https://adwords.google.com/select/
TrafficEstimatorSandbox) will be updated to prevent users from
entering proximity or polygon targets. The AdWords API team will not
be making any changes to the v13 TrafficEstimatorService WSDLs at this
point, but I have asked our documentation team to make it clear in the
docs that any proximityTargets you pass in to the service will be
ignored.
Cheers,
-Jeff Posnick, AdWords API Team
