Adwords SearchVolume API returns lower case keyword

[li_c...@monotaro.com]

Hello,

My Problem:

I am using Google Adwords TargetingIdea Service. When I use it to get STATUS information of existing keywords, when I give the API a keyword like "A4 paper", its response will be like below:

Type_AttributeMapEntry){

               key = "KEYWORD_TEXT"

               value =

                  (StringAttribute){

                     Attribute.Type = "StringAttribute"

                     value = "a4 paper"

                  }

I have tested several keywords with upper case and they all become lower case in the response. Is there any document about how my keywords sent to the API will change?

How it affect my work:

 

It's just like I have a table, the keywords are all in the table and I just want to fill in the search volume information. But now if I send 100 keywords to this API, I am likely to get only 50 results(those keywords without results seem not to be returned).

And what's more, I will get results with lower case no matter what I've sent. And I don't know will there be any other normalization applied to my keywords, so I am actually unable to match the keywords with the results.

Now I am sending the keywords one by one to avoid chaos, but one by one is really really slow.

Please help me with it. At least if only I know how the API will normalize my keywords, I will be able to match the keywords before and after successfully.

Or if there is anything I didn't notice that may help, please kindly tell me. 

Thanks in advance.

Hello, 

Irrespective of the case in which you pass your input, the API will convert that to lower case in the response. You can see that the behavior is same in the UI as well. You could perhaps have your logic to perform the matching based on this. You are right about some keywords not returning results. In most cases, it is because there are no stats for the specific keyword. However, the results of TargetingIdeaService should be consistent with the results of Keyword planner UI. 

If you continue to have an issue with this, could you provide us the SOAP logs of your request? I can take a look at that and guide you further. Please use Reply privately to author option to provide the details.
