Danny Sullivan reports that Google is experimenting with another revision to its search results pages. He says Google appears to be "testing a move away from showing the traditional 10 listings to only displaying seven." What's more, Google also seems to be displaying more results from the same site -- meaning that "it’s even easier than ever for one site to dominates all those results," he notes. Google told Sullivan the company is "continuing to work out the best ways to show multiple results from a single site, when it’s clear users are interested in that site." The company also says it is "experimenting with varying the number of results per page."
