The group said Revenue Science would allow it to help advertisers closely target online campaigns to more receptive audiences and heighten investment return.
Ken Breen, print and online sales director at the Telegraph, said: "Revenue Science's technology will let our advertisers deliver their campaigns directly to specific segments of our 6.4m unique users -- no matter what part of the site they are on."
He added that the resource was part of the Telegraph 's commitment to improving revenue generation for its advertisers.
Richard Foster, UK managing director of Revenue Science, said: "UK advertisers and agencies have rapidly integrated behavioural targeting into their media strategies so this agreement can only increase the stature of a premium media property like telegraph.co.uk."
In May, the Telegraph redesigned its homepage to offer improved usability, streamlined content and revamped blogging technology after completing a six-month user opinion study.
The title has undergone significant changes to its online edition in the last year, including the expansion of its editorial department and making Ken Breen print and online sales director.
