Researchers explain why 10-second micro ads outperform longer spots

A team of researchers say they have demonstrated that ultra-short ‘micro ads’ lasting 10 seconds or less are significantly more effective than longer, more elaborate advertisements at driving immediate online visits and consumer engagement. 

They evaluated the effectiveness of micro ads using a multi-method approach that included TV advertising data and a field experiment involving social media advertisements for a non-profit organisation.  

Their results showed that micro ads of 10 seconds or less aired on television increased website visits within five minutes of airing by 10% to 40% compared with longer advertisements. The micro ads outperformed even 30-second ads by 13% to 28%. 

In social media environments, shorter micro ads also generated more clicks and greater community engagement, including likes and shares, even when they conveyed the same information as longer ads. 

The research team was led by Professor Inyoung Chae of Sungkyunkwan University in South Korea, together with Professor Beth L. Fossen of Indiana University and Professor Philip Kim of Texas Christian University. The latter two institutions are in the US. 

Their study, titled ‘The Impact of Ad Length on Ad Effectiveness: Do Micro Ads Work?’, is published in the Journal of Marketing. 

Consumer impatience is a key factor 

The researchers identified impatience as a key factor behind the micro ads phenomenon. When viewers in the experiment were first nudged to think about the future, a prompt that encourages patience, the advantage of micro ads disappeared. 

“While consumers may easily become bored or lose concentration when watching longer advertisements, short ads that communicate their key message quickly reduce the burden on viewers and are more likely to prompt immediate actions such as online searches or website visits,” they say. 

“In particular, micro ads that revealed the brand name early rather than withholding it, and that used language that built anticipation, were especially effective at driving website traffic,” the team note. 

“The findings offer an economical and practical marketing strategy for companies facing rising advertising production and placement costs amid changes in the media environment.  

“In addition to being less expensive to produce, micro ads can substantially reduce TV advertising costs, allowing companies to attract considerably more consumers with the same advertising budget.”
