Friday, Google started showing a new "show more results from" link in the Google search results listings. The new link is an AJAX like link that dynamically expands the page to show you five more listings from that site. In the past, clicking on the link would take you to a site command flavored search page, thus sending a new query to Google and taking you to a new page.
Here are pictures of the new way Google is handling this:
I have a picture of the old way from a 2005 post:
The new way is much faster for the searcher, but might lead to less queries per user for Google (a stat thing), unless Google is tracking the click on the "more" link as a query, but would comScore and HitWise consider it a new query?
