Google has confirmed with Search Engine Land that it is testing new user interface for the core search results pages. This new test features a rounded search bar at the top, a smaller Google logo, and, most noticeably, the search bar header sticks to the top as a user scrolls through the results.
This was first spotted in a Reddit thread and Google confirmed this is one of its many tests. A Google spokesperson said, “We’re always experimenting with new ways to improve the Search experience for our users.”

Google is frequently testing user interfaces but this test involves the most drastic changes in the core search product that we have seen in a long time.
