Twitter has commissioned data from Nielsen and Foursquare to evaluate its impact on offline sales and store visits. The results:

  • Promoted campaigns on Twitter generate a 23% lift in visits to mobile carrier storefronts
  • Buyers spend 6.8% more with mobile wireless carriers after seeing ads on Twitter
  • Offer-based tech and telco campaigns on Twitter generate a $21.84 average return on advertising sales investment
  • Twitter users are 2.4X more influenced by manufacturer and mobile carrier ads

Why it matters: Facebook, Google and Snapchat have all released similar data that demonstrate their ability to help marketers drive offline sales through ads on their platform. The expectation has been set with marketers that if you are a platform that can reach an audience at scale, you should be able to track how mass marketing drives actual sales in stores, as well as sales from the platform directly.

Sen. Elizabeth Warren and Hillary Clinton both are slated to speak on the Wednesday of the Democratic convention — Aug. 19 — four sources familiar with the planning told Axios.

Why it matters: That's the same night Joe Biden's running mate (to be revealed next week) will address the nation. Clinton and Warren represent two of the most influential wise-women of Democratic politics with the potential to turn out millions of establishment and progressive voters in November.

Trump considering order on pre-existing condition protections, which already exist

President Trump announced on Friday he will pursue an executive order requiring insurance companies to cover pre-existing conditions, something that is already law.

Why it matters: The Affordable Care Act already requires insurers to cover pre-existing conditions. The Trump administration is currently arguing in a case before the Supreme Court to strike down that very law — including its pre-existing condition protections.
