Hi all,
I am using the most recent version of Adwords API (v201309) and I am having
problems with Traffic Estimator service.
When I perform the a query through API, results don't match with UI.
For example, I want to do a query to find the estimated traffic for the
keyword "sapato masculino" (men's shoes), restricted to Brazil and
Portuguese language. I do it for a set of bids, in order to find out the
best initial bit to set up on my keyword settigns. The problem is that when
I do the same query through Adwords UI, it results in different numbers.
API's results are always more optimist. When I set the bit to a high value,
such as R$ 999999,99, the number of impressions are the same for the both
results. But the maximum values for average position, cpc and CTR (and,
consequently, number of clicks) is never the same --> API's results are
better then UI's. Of course, I am using the same account for the both of
methods...
Can somebody helps me please?
Following is my source code (in C#). I perform the test for values from
R$0,01 to R$0,10. Only the maximum number of impressions matches with UI's
results:
