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“.
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.
