There’s been a lot of talk over the last month or so on mega sitelinks however I noticed something different in the SERPs today.

When I typed in my blog name “seounique” in Google I saw underneath the 6 extended sitelinks an extra site result. This extra site listing rotated per different search;

A different result on the same query:

I noticed something new in Google (or at least I’ve never seen it before) – next to the “Cached” link on a domain there’s seems to be a link displaying “Block all content www.domain.com results“.

See the screen grab below with the links and placement:

The result being shown in Google was an archive page for a blog and was ranking number 1 so perhaps there’s a filter on these types of pages when in prominent positions?

When you hover the mouse on the listing the following popup is shown:

Quite interesting that Google are pushing more people to be signed in – supports their drive for +1′s over the recent months.

** Update – I managed to replicate this for all sites now. Simply click on any website in Google and click “back” in your browser within a short time period and the addition to the results for that website will be shown. This does NOT happen if you stay on the site for over a minute.

If anyone else has seen something similar I’d be interested to hear.
