Hi Eric,
I've done some more digging, and the zero estimates for some keywords
is due to effective duplicates. Consider your request using the
following keywords:
1) injury attorney san diego
2) injury attorneys san diego
3) san diego injury attorney
4) attorney diego injury san
5) san diego injury attorneys
All the keywords are BROAD match, which means that the order of the
words doesn't matter. This means that keywords #1, #3, and #4 are
equivalent. Likewise keywords #2 and #5 are equivalent. Because
these are all within the same AdGroupEstimateRequest, the TES is
estimating how much traffic these keywords would receive if they were
all added to the same ad group. Because of the effective duplicate
keywords, all of the traffic is being assigned to one of them (in this
case the first appearance) and the others are assigned zero traffic.
If you want to evaluate each of these keywords independently, then you
need to wrap them in their own AdGroupEstimateRequest.
Best,
- Eric
