In June 2011, Google introduced "Google Voice Search" and "Search by Image". This helps the users to search words by voice and by using an image.

In 2012, Google changed its rankings to demote sites that had been accused of piracy (except YouTube). Google has a lot of search results to display in various forms.

Google has a feature called as "Google Doodle". On certain occasions, the logo of Google will be displayed in a picture, drawing, or animation. It is usually done for a special event or day although not all of them are well known. If a user clicks on the Doodle, the Google Search page is displayed which has results for the topic/occasion. Google also identifies the misspelled words in the search box and display results with the correct word search. This is accompanied with a note ‘Showing result for XX’
