Co-founder of the Sleeping Giants campaign, and now brand safety consultancy service Check My Ads, Nandini Jammi was a tech marketing generalist until she stumbled into the murky world of online adverts – more specifically, the kind of sites where they could end up. While she admits it’s hard for all marketers to be ad tech experts, she has spent the last 4 years campaigning for brands to proactively check where their ads are placed, and stop supporting websites that promote hate or disinformation. Nandini tells Jane and Felipe about the pitfalls for advertisers when they focus solely on reach, how her campaigning has changed consumer culture, and the “win-win” of clearly aligning your marketing – and online advertising placement – with your brand values.
