"Enable regulated businesses to meet retention or audit requirements." For example, marketers in the spirits industry tend to disable content and ad delivery to consumers under 21, regardless of the local drinking age where a message is seen. Given the right filtering tools, a Diageo or Anheuser-Busch CMO might green-light targeting 19 year-olds in places where the drinking age is 18. Or so Twitter hopes.
"Recommend content for a brand or publisher to tweet or promote." See above regarding Promoted Products.
While the Certified Products program does not have a strong ad integration at this time, there's unquestionably an opportunity for Twitter to ramp up its Promoted Products by creating an Ads API and allowing third parties to bring demand to the table. A rep declined to comment on when or if that might happen.
Meanwhile at least one e-commerce marketer is suggesting inbound traffic from Twitter performs better than other social platforms. A Zappos exec cited by Bloomberg reported that user posts on Twitter delivered average revenue-per-order of $33.66, well above Facebook and Pinterest. Facebook posts brought in $2.08 whereas Pinterest posts averaged a mere $0.75. (This appears to be part of a test conducted by Zappos Labs, not necessarily applicable to all Zappos-bound Twitter traffic)
“Even if a person has 100,000 followers on Pinterest and she pins something to a board called ‘Stuff I Love,’ that’s not as big a deal as an endorsement tweeted to 10,000 followers,” Will Young, director of Zappos Labs, told Bloomberg.
