Strange Top URLs for Keywords in Google Webmaster Tools

[Hakkasan]

When we click on one of our keywords under the keywords section of Google Webmaster Tools it shows our top URLs for that keyword. The problem is that it is giving us some very strange URLs that we have searched high and low to try to find but we don't know where they came from.

Here is a screenshot: http://bit.ly/pl6mB3

Do you know where this type of URL string could have originated and how to fix it?

Weird! It looks like an IP address but I can't find any info when I run it in a ip address / domain checker. It also does not resolve in the browser. However, to the left of those mystery URLs is a little box with an arrow in it that takes you to the page... can you click that and tell us what page you get?

Clicking on the little box opens up the homepage of our site, for all the strings with numbers in them.

Obviously they are not all representing the homepage, otherwise they wouldn't all show up as different URLs, right?

I just don't know. Would you mind putting in the URL to your homepage. I am just going to scan the code for anything unusual. I once had some strange code show up on every page of my group of personal websites. I somehow got hacked. It is a shot in the dark but I don't mind doing a quick scan.

You may also want to post this on the Google Webmaster blog as well. Also, if you do any paid advertising with Google.. ask your account rep.
