Traffic Estimator Service returning DistinctError.DUPLICATE_ELEMENT

[Christian Borck]

This question is related to the traffic estimator. We like to get several estimates for a keyword (i.e. estimates for three different max-cpcs). Currently we’re doing three separate requests, one for each max-cpc. In an attempt to optimize this, we combined the three requests into one. As a result, we get duplicate-element errors (DistinctError.DUPLICATE_ELEMENT). Does this mean, that we can only have one estimate per keyword per request? The API documentation for AdGroupEstimateRequest states for the field keywordEstimateRequests: … This field must contain distinct elements … However, we’re unsure what „distinct“ means in this context; is only the keyword-id relevant?

The keywords we are estimating are existing keywords, thus the request

contains a campaign-id, ad-group-ids and keyword-ids.

Hi Christian,

You can send multiple keywords per request, see https://groups.google.com/d/msgid/adwords-api/bec89d9c-9720-4ed3-9ed7-fa0cd3644732%40googlegroups.com?utm_medium=email&utm_source=footer for an example.

Hi Anash,

Thanks for your quick reply. Unfortunately your link doesn't work properly.

I know, in fact we are sending multiple keywords per request already.
The issue is getting estimates for a distinct keyword, but for different maxCpc's within a single request, eg. estimates for:
"buy shoes" with maxCpc 0.5$
"buy shoes" with maxCpc 1.0$

Best regards,
Christian

Hi Christian, 

Apologies for the wrong link, I meant this link: https://github.com/googleads/googleads-dotnet-lib/blob/master/examples/AdWords/CSharp/v201409/Optimization/EstimateKeywordTraffic.cs

I think we allow only estimates for distinct keywords in a single request, even though the bid range is different. In your case, you'd need to send multiple requests.

Cheers,
Anash

Hi Christian,

I apologize, the original link should be https://github.com/googleads/googleads-dotnet-lib/blob/master/examples/AdWords/CSharp/v201409/Optimization/EstimateKeywordTraffic.cs

That said, we don't support sending duplicate keywords in a single request, even though the bids being requested are separate. I'm afraid you can't optimize the requests by packing both estimates into a single API call.
