A new feature has been launched by Google, which allows users to track down their own content. When a search is performed through the search engine, those signed into their Google account will now be able to click on the Personal tab to see results pulled from their Gmail, Google+ and Google Photo accounts. Each user will only be able to see their own personal results, which might include photos of a location they have visited if they search for that particular place. Advertisers will be able to use the service, with advertising space being available at the bottom of the page. The service is not currently available worldwide, and seems to be rolling out gradually instead.
