Same gclid from different MCC

[Igor Selitsky]

Hi, today I've found duplicate gclid for two different MCC:

# downloaded_at, date, click_id, click_type, gclick_id, page, slot, device, city, region, country, ad_network_1, ad_network_2, ad_id, keyword_placement, keyword_id, keyword, ad_group_id, ad_group, campaign_id, campaign, account_id, MCC
'2016-03-23 03:59:36', '2016-03-21', '0', 'Headline', 'CJq41oWE0ssCFYIxcgodbyMAqw', '1', 'Google Display Network', 'Computers', '--', '--', 'Kazakhstan', 'Display Network', 'Display Network', '82037994737', 'docvertical::3', '1543465137', NULL, '23247161057', '', '262968137', '', '9251561922', 1
'2016-03-23 04:52:12', '2016-03-21', '0', 'Headline', 'CJq41OWE0ssCFYIxcgodbyMAqw', '1', 'Google Display Network', 'Computers', '--', 'Republic of Karelia', 'Russia', 'Display Network', 'Display Network', '90903864965', '', '3000000', NULL, '24207521165', '', '352657205', '', '2602708616', 2

How does this possible? how better to handle such situations?

This is data from click performance report. Last column is MCC number.

Hello, 

Could you please provide report definition? Did you run the same report using two different MCC accounts? 

Thanks,

Yin, AdWords API Team. 

[Igor Selitsky]

Hi, yes the same report for two different MCC.

It's fragment of report result for last 5 days.

Header is in the first message.  Do you need exact report definition?

[Umesh Dengale]

Hello,

Could you provide me privately the clientCustomerIds for CLICK_PERFORMANCE_REPORT and report request definition? Just click Reply privately to author in the forum when responding.

Hi, I sent all information privately and I got answer that this is a bug. So I'm waiting for resolution of the issue.

Hello Igor,

Thanks for checking in. I was talking with one of my teammates, and it sounds like there is a slight probability that there could be a collision in click IDs. I think that's what you're seeing here. I'm checking with him to see if there's a way we can avoid that from happening in the future.

Best,

What was the result of this query. Was there in actual fact the same Unique GCLID's across accounts. Thanks Goran

[Nadine Sundquist (AdWords API Team)]

Hi Goran,

Yes, there is a small probability that there could be the same GCLIDs showing up across accounts. 

Cheers,
