Anyone seen this before? ? gwt pg=
strange code tagged on the end of URL by google

Has anyone seen?_gwt_pg= tagged on to the end of a URL before?
Looks like google are tagging it on to the end of URL's, but why?

I can see it too, but I don't know what it means :-\

There was a thread here about query strings about six months ago - redirecting them if you don't use them on your site, especially if they return a "200 OK" status code.

I think it's a good guess that gwt="google webmaster tools". I don't make much use of GWT -- is there some way that you can tag specific urls from within your account?

I'm not sure what those parameters are, but they're not coming from webmaster tools.

We have seen it as well, I am going to look through my logs for ip addresses where the query is coming from.

vanessafox, thank you for providing that information.

Folks if it is a search engine bot that is looking for those pages you have a problem brewing.

See the sticky thread at the top of this forum.

The threads about duplicate content speak to this.

Thanks theBear,
But there are a couple of threads about dupe content in the stickies.
Have you a direct link to the post talking about?_gwt_pg=

The IP adresses come from google.

The IP's are coming from google. Something you might want to look into.

Could it possibly be this?

I think that's for the reformatting that google does on pages when I search google from my Treo phone. Google actually reformats the webpage after you click through the SERP so that you can more easily see it on your phone.

Ah, rather than try to explain it just see it for yourself by searching here in your normal browser to see what folks see on their phone:

I'm not sure if websites are all going to be happy about this, but from the treo user perspective it's usually a good thing.

I couldn't replicate the same string exactly, but get something very
similar when going via google mobile at,
It also shows up in my stats as coming via a google IP number

It makes a lot of sense, the pages that whoever was looking at, were my mobile phone pages.
Thanks again.

Quick follow up to anyone interested.
GWT apparently stands for
Google Wireless Transcoder

Aha. If it's the wireless transcoder, then you can learn more about that here:
