Click Performance Report return not all gclids

[Igor Selitskiy]

I compare number of unknown gclids (cannot get details about campaign)  in Google Analytics BigQuery data and in ClickPerformanceReport and found that AdWords doesn't export a lot of gclids in this report.

Proportion is about 1/5.

Why AdWords doesn't return so many gclids in click performance report, but show this in GA?

Do you plan to change it in future?

Query for getting number of unknown gclids from BQ data:

select date, count(1) as sessions 

FROM `XXXX.ga_sessions_20161*` 

where trafficSource.adwordsClickInfo.gclId is not null

and trafficSource.adwordsClickInfo.customerId  is  null

group by date order by date

Hi Igor,

There are various reasons why AdWords and Analytics may report different number of clicks, some of which are listed here. In this case, it could be that AdWords considered some clicks to be invalid and filtered them from your AdWords reports. If users bookmark your website along with the gclid parameter, AdWords doesn't record these clicks, but Analytics records traffic from these bookmarks. I would suggest that you check your auto-tagging and AdWords Import and Export settings. If you still find that the discrepancy is significant, please provide your clientCustomerId so I can further investigate. 

Thanks,

Shwetha, AdWords API Team.

As described in adwords API documentation, click performance report contains all clicks: valid and invalid.

Hi Igor,

Yes, Click Performance Report includes both valid and invalid clicks. Could you provide a sample of GCLIDs which haven't been reported in AdWords? I see that you are checking if the customerId is null for these clicks. You can use the checklist provided here to make sure everything is set up properly.
