Same site showing twice for a keyword search!

Just noticed this - has anyone seen it before?

For a popular keyword search, i am getting the exact same url showing at #1 and #12 in google.com

Is this only part of the rolling update? Has anyone noticed it before?

I haven't seen this myself, but I had this thought... Is one with a trailing slash, and one without?

[netnerd]

Nope - they are EXACTLY the same.

But it has since disappeared. Must have been a little insight into googles update?

There was another discussion here a week or two ago that revolved around the update schedule.

I see this fairly often. The site appears at the same position on page 2 and sometimes page 3 as it does on page 1.

e.g. Position 3 also has position 13 and position 23....all the same identical root URL. It is always 10 places further down the SERPs, suggesting any switching of data centers when hitting next page or other technical explanation of flux isn't the cause.

I figured it was a Google glitch, and as it is most often my sites I notice this for decided not to complain ;)
