Facebook is teaming up with Nielsen, which measures television and other media audiences, to provide information to marketers about ads on the Palo Alto social-networking company`s site.

The new Nielsen BrandLift program will use opt-in polls to survey a sample of Facebook`s users about "consumer attitudes and purchase intent" resulting from display advertising on the site, the two companies said Tuesday.

"Nielsen is the leader in measurement and is an excellent partner for us as we look to provide marketers with richer ad effectiveness data," Facebook Chief Operating Officer Sheryl Sandberg said in a statement.

"The combination of our unique ability to quickly and effectively poll a sample of our more than 300 million users and Nielsen`s expertise in data analysis will give marketers access to powerful data they can use to understand and improve current and future campaigns," Sandberg said.

The companies said no personally identifiable information will be shared with marketers.
