Is this new?
I've stumbled on a query where the last result on the first page is the EXACT same result as the first one on the second page.
The result has authorship details and seems to have been boosted as a result.
Only three normal serps show on the front page. It's dominated by local results. The second page also includes two local results.
Find it quite peculiar that the exact same page effectively ranks in third and fourth spot.
