Google Tracking URLs

I have seen i in multiple areas

[ukgimp]

I figure this is just small scale experiments but as of today they are doing it in at least three different sectors

google.com/url?sa=U&start=X&q=http://etc../&e=Y

X = serp position
Y = static number which appears to be the same across industries.

What do you make of it?

Cheers

Yep, they do this now and again. I think it's to try to measure quality after they tweak the listings.

Presumably, the more clicks towards the top of the rankings, the better?

I think it was every 0,5% to 1% of queries they try it on?

I've been noticing the tracking on all searches I've been doing over the past week or longer.

I can't find any SERPs that don't have the tracking.

<added> Another WW member kindly reminded me to delete my cookies, clear my cache, and try again. Which I did and no longer see the tracking. There was a thread some time back that explained about this, but haven't been able to find that thread. <added>

Most probably a category (dmoz?) id,then.
