Twitter has just launched a new feature aimed at helping advertisers deliver more targeted tweets.

Demographic dig down

Twitter's Partner Audiences feature was announced in a blog post. 

"With partner audiences, you can now target Twitter Ads to users who have shown powerful signals of intent off of Twitter — helping you drive the highest possible ROI with your advertising campaigns," wrote Kyle Boston, Twitter's Product Manger, Revenue.

Zero in

Twitter has partnered with analytics outfits Axicom and Detalogix to give marketers over 1000 partner audiences to choose from.

For example, an auto brand might partner with a car retailer to share data about recent user purchases.

Twitter used the example of Nestle, who used Partner Audiences to target users who frequently purchase peanut butter sweets in grocery stores.

The resulting Promoted Tweets campaign saw a 52% boost in engagement for its @Butterfinger product. 

Privacy play

Twitter explained that users can opt out of sharing their information by unchecking the "Tailor ads based on information shared by ad partners" box under Privacy Settings.

Partner Audiences is now rolling out in the US through Twitter's Ads API partners.
