Local News Works: Testing the Effectiveness of Local News Placements
Written By: Fil Lourenco, VP, Performance & Platforms at Dentsu Media
We recently ran a 3-month test to prove the effectiveness of local news placements. We partnered with The Trade Desk to A/B test local news vs. non-news inventory, building a robust testing and measurement framework to track the media effectiveness.
Here’s what we learned:
Local news is a fundamental pillar of a healthy media ecosystem, and our local news outlets are struggling. Too often local news ends up on block lists due to brand safety concerns or is deprioritized to open exchange because of costs. This means advertisers are missing out on high quality and trusted media environments that capture the attention of Canadians.
The message is simple. Invest in what works. Invest in local news.
Shoutout to Amy Apostolou & Roohi Mudgil for putting this test together. I am lucky to have such an amazing team.
Extra shoutout to our local news partners who were a part of this: Postmedia Network Inc., Village Media, Toronto Star, The Globe and Mail, CBC, Corus Entertainment, Bell Media & Rogers Sports & Media.
Free, fast, and read by 8,000+ marketers, founders, and comms pros across the country.
