A couple weeks ago, we reported Google is showing only seven search results when the search query is specific enough to warrant less results.
To my surprise, it seems like Google is cutting that number to only show four search results!
Yes, a WebmasterWorld thread has one searcher noticing for search results that return sitelinks, instead of showing seven results, it is now showing only four results.
This seems to be a test, I cannot replicate the test myself but the screen captures seem legit.
As you can see, Google took this down from ten, which came down from seven and now is only showing four results.
I am not sure if Google has serious intentions of only showing four search results on a page or not, but they seem to be testing it.
The WebmasterWorld thread has one more picture as well.
