Missing gclids

Visitor ✭ ✭ ✭

We have auto-tagging turned on in AdWords and most of the time the traffic going to our landing pages contains gclid as a querystring parameter. However, occasionally it does not. While reviewing the IIS log files, anywhere from 5% up to 14% of the landing page requests do not have gclid parameters. The rest of the querystring parameters are there and populated so it isn't the result of a bad 301 redirect. I have also eliminated all of the requests by bots. There is no consistency in which page requests are missing the gclids or in the referring sites. Why are some of the page requests missing the gclid parameter?

Hi KrisAmOne,

You say you have eliminated all requests by bots. You haven't blocked all bots, other than AdsBot? That would allow search engines to index your landing page and to show that page in SERP organic results. Clicks on organic results won't include the gclid.

You also say "the rest of the querystring parameters are there and populated". Are these Value Track parameters, or something else?

No bots are blocked, although all PPC landing pages have noindex on them. When I calculated the percentage of missing gclids, I eliminated all page requests by bots so as not to overstate the percentage of missing gclids. The rest of the querystring parameters are only those found in our AdWords destination URLs, some of which are populated by Value Track parameters. I can understand some bots using the destination URLs anyway, but how would the Value Track parameters be populated if not coming from Google? Google is also in the IIS log files as the referring source.

Hi KrisAmOne,

That's why I was asking. If the Value Track parameters are being populated, I don't know why the gclid would not be also.

I'm going to escalate this to Google support.

No, not really. I started working with Google support directly. They kept coming up with reasons why it could be missing, but it was all the same reasons you can find in an internet search. I kept responding on how it was not what they suggested and provided all the documentation to show why each of their reasons was not applicable in this case and could be eliminated.
One of their responses was:


there are automated checks (Google Analytics Diagnostics) now to verify that auto-tagging is working correctly or not. So far it has not diagnosed any irregularities in your setup

Since most of our PPC landing page requests had a gclid and it was working well enough for us, I gave up and stopped wasting my time with their run-around.

Did you ever resolve the problem? We are also seeing gclids missing for about 5% of the clicks.

No, I just gave up and learned to work around the discrepancies.
