Is Google AdWords not tracking some of its traffic?
I actually noticed this many months ago, I spoke to our contact at Google Adwords who said they would pass it onto their engineers to look at. Months later I am still seeing the problem so I thought I’d put it out there and see if I’m being really silly and overlooking an obvious answer, or if Google really is broken.
As part of any good Adwords campaign, auto-tagging is turned on and linked to a Google Analytics account. Auto-tagging will tag a unique ID to the end of a URL so that when someone clicks on one of your Ads, the info about that click is passed across into your Analytics account for better analysis. When switched on, the Ad you click on will lead to a URL like this -
http://www.example.com/?gclid=fggewrtw5t4wywrr34t3twe
However if you click on the “more sponsored links” below the Ads, you will see a page like this -

If you click on one of these links, no tag is added to the link. Does this mean that they are not being tracked in Analytics at all? I doubt that a huge amount of people actually choose to search just sponsored links or click on the more sponsored links however surely data is being lost here?
Any ideas anyone?

@paddymoogan I just checked it out and you are spot on – there is no gclid on landing pages directed from sponsored links pages. But have a second look at the URL of a sponsored link page – take this page for example:
http://www.google.co.uk/sponsoredlinks?q=apple+iphone+3g&hl=en&rlz=1B3GGGL_enGB306GB306&um=1&ie=UTF-8
variable available –
sponsoredlinks
q=apple+iphone+3g
hl=en
rlz=1B3GGGL_enGB306GB306
These surely are passed unto analytics – probably not as accurate as gclid but does the job.

I can see what you mean from that link, but I can’t seem to replicate this. For example using the same query as you I get the following URL –
http://www.google.co.uk/sponsoredlinks?q=apple+iphone+3g&hl=en&safe=off&um=1&ie=UTF-8
I seem to be missing the tlz variable. I can’t see any of the other variables passing across any info apart from source and keyword.
