Digital marketing spends its energy on platforms, bidding and attribution, while what ads actually say has become an afterthought. We tested that assumption for Informa's Vitafoods Insights: four creative pairs, one word changed per pair, nothing else.
REBEL manages paid media for Vitafoods Insights, one of Informa Markets' flagship nutraceutical newsletter brands. Campaigns run across Google Display targeting professionals in EMEA, the USA and APAC, with content engagement and newsletter sign-ups as the primary objectives.
The Vitafoods Europe Trend Guide is a key annual content asset and a recurring paid campaign, which makes it the perfect vehicle for structured creative testing: the brief is consistent, the audience is established and performance benchmarks already exist.
The psychological mechanics of language are documented, replicable effects: verbs encode agency, specificity signals relevance, framing shapes perceived value. The published research is decades deep. The question is not whether these effects exist, it is whether advertisers are paying attention.
We designed a test to find out whether they hold for a B2B nutraceutical audience across three regions: identical images, identical CTAs, and only the headline verb or phrase changed.
A structured A/B test across four creative sets, running from 27 May to 5 June 2026 across EMEA, the USA and APAC. For each pair the hero image and CTA were held constant, so any performance gap is attributable to the words alone.
Same image, same CTA, same audience. Only the key word or phrase in the headline changed, so the result means something.
Verb agency, linguistic concreteness and value framing from published psychology, tested in-market rather than assumed.
EMEA, USA and APAC measured separately, because language cues do not land identically everywhere.
Impression distribution between versions was algorithm-driven and uneven for some creatives, so CTRs are most meaningful at the individual creative level. The pattern across the test, though, is exactly what the research predicts.
