Google has provided more details about the recent changes to its search results page.

Jon Wiley, senior user experience designer at Google, said in a blog post that the new layout is an effort to meet the "rising expectations for search" from increasingly web savvy users.

"As the web has evolved over the past decade, people have been typing more sophisticated searches and seeking specialised search tools to match. Our goal was to take a design known by millions of people and make it better," he said.

Wiley also explained that Google had spent a lot of time working on the left-hand navigation panel in order to offer the best balance of additional functionality without distracting from the primary search results.
