One word best describes the Google search engine interface: simplicity. The search screen contains little else besides the logo, the search bar, and a few links. The results list is plain and to-the-point. This concept may be one of the reasons so many people find it easy to use.

But it’s also in need of an upgrade. While Google’s search algorithms are in a state of continual refinement, the user interface hasn’t changed much over the years. They’re working on this, and big changes are near. And they want your help.

Google is now offering its experimental search page, where users can try out one of five different interfaces to the search engine. Options include a timeline of results, keyboard shortcuts, suggested alternative keywords, and a new right- or left-hand navigation box.

Don’t get too carried away — you can only try out one of these options at once. But once you choose an experimental option, that choice will be displayed every time you perform a Google search.
