Google ads API results vastly different to actual results

[Daan Jan Grotenhuis]

Hi everyone, I'm trying to use the keyword planner api (specically the histroical metrics ones). However, I'm getting vastly different results (ive checked stuff like country, lnaugage, google only results). Is this a common and known issue?

Hi,

 

Thank you for contacting the Google Ads API support team. 

 

Upon reviewing your concern, I understand that you are using the KeywordPlanIdeaService.GenerateKeywordHistoricalMetrics service and are observing some discrepancies between the Google Ads UI and Google Ads API. In order to assist you further, please provide us with the following information:

 

1. The discrepancy which you have observed.

 

2. Uncropped UI screenshot of your Google Ads account with which you are comparing the API data highlighting the fields for which discrepancy is observed with the visibility of your Google Ads customer Id.

 

3. The complete API logs (request and response with request-id and request header) generated at your end without redacting any information. If you are using a client library and haven't enabled the logging yet, I would request you to enable logging for the specific client library that you are using. You can refer to the guides Java, .Net, PHP, Python, Ruby or Perl to enable logging at your end. For REST interface requests, you can enable logging via the curl command by using the -i flag.

 

You can send the details via Reply privately to the author option, or direct private reply to this email.

 

Thanks,
 

Google Ads API Team
