Internet titan Google Inc has acquired two startup firms -- Apture and Katango -- for an undisclosed amount that would help it enhance the user experience of its browser and social networking services.
The 4-year old Apture focuses on providing instant access to information with in-page search technology.
Katango, on the other hand, was founded a little over a year ago and builds algorithms for automatically sorting friends that improves online social interaction.
However, financial terms of the deals were not disclosed.
Google buyout of Apture is expected to bolster the firm's Chrome browser.
"We have been acquired by Google and will be joining the Chrome team to continue driving innovation and creating a better user experience on the web," Apture said on its site.
The acquisition of Katango will help over 40 million users of internet search giant's social networking platform Google Plus to organise their circles. Katango's technology is similar to the circles feature on Google Plus, which helps users to group their contacts easily.
