Lowercase GCLID Requests Problem

[Nadav De Bruin]

Some of the AdWords redirections we get on our site comes with lower-case gclid value.

When we report offline to AdWords by AdWords API with this lower-case gclid we get an error back saying: “OfflineConversionError.UNPARSEABLE_GCLID”.

From the start of the implementation 2 month ago, we get about 1-5 lower-cased gclids requests each day. All the other requests are OK.

All adds are defined to link directly to our site – www.daka90.co.il so there is not a possibility that the lower-case behavior is caused by some other redirection than Google.

And there are any changes in URL rewriting engine in their website.

View this one of the lower-cased  gclid request info we get in our ASP.NET global.asax file using System.Web.HttpApplication.Request.ToRaw(),

The Referer property marked with yellow points that the request came directly from Google.

When we look for those lower-cased gclids in the CLICK_PERFORMANCE_REPORT we can not find then there.

We can find all the other not lower-cased gclids there.

Please help,

Hi Nadav,

Could you send me the click date and client customer ID for the GCLID below?

Thanks,

Josh, AdWords API Team

Click date: 19-07-2017
Client Customer ID: 272-772-9533

Hi Nadav,

Thanks for sending that over. I ran a CLICK_PERFORMANCE_REPORT for that customer and noticed that it contained a row that matched the GCLID if I: a) ignore case, and b) add an additional hyphen (-).

GCLID you sent over:

cjwkeajwhrzlbrc35-f9ssh0fasjad5obj1kylnrwqus0vztbm1qkc7lapsc6cxnsvraz7__9a5wrocaqdw_wcb 

GCLID in the report for July 19 2017:

CjwKEAjwhrzLBRC35--F9sSH0FASJAD5obJ1KYLnRWQuS0VzTBM1QKc7LaPsc6CxNsVRaZ7__9A5wRoCaqDw_wcB 

Are the requests going through a proxy or load balancer on your side that is changing the case of parameters and removing double hyphens?

Thanks,

Josh, AdWords API Team

Thanks Josh,

The 2 hyphens,  as you wrote, are cause the gclid to change in our site.

We'll search our  proxies, load balancers, any rewrite engines etc.. to fix it.
