Almost three-quarters (63%) of consumers would respond more positively to a social media ad if it appeared on a more traditional advertising channel, according to a new report from the CMO Council.

Having surveyed 2,000 adults across the UK, US and Canada, it found that despite delivering the second highest volume of advertising messages, social media platforms were the least trusted by consumers among the top five media channels.

And although the study is just a snapshot, marketers might still feel alarm with just over 40% of those polled revealing they already have ad blocking software installed on their devices. Another 14% plan to add an ad blocker to their devices in the near future.

A big reason behind the social media dismay, the research claims, is a lack of trust and the rise of objectionable content. Some 60% of consumers state that offensive content appearing on the likes of Facebook and Twitter had already caused them to “consume more content from trusted, well-known news sources and established media channels”.

Following an investigation by The Times that revealed ads being placed next to extremist content on sites such as YouTube, the public concerns expressed by marketers such as P&G’s Marc Pritchard have been hard to avoid.

However, according to the CMO Council study, the concerns of marketers are being shared by consumers. In fact, 48% will abandon even brands that they love, should they see their ads appear next to ‘objectionable’ online content or on fake news sites.

And some 37% of consumers say this would “change the way [they] think of a brand when making a decision to buy”. Another 11% would flat-out “not do business with that brand” while 9% say they would become vocal critics of the brand.

“CMOs and brand advertisers are increasingly concerned about various aspects of digital and programmatic advertising, including concerns about their ads showing up next to offensive content,” says Donovan Neale-May, executive director of the CMO Council.

“This consumer survey demonstrates that those concerns are well founded. Advertising placed next to objectionable content is damaging to a brand, while ads that accompany more trusted content and media are more accepted.”
