Marketing has reached a tipping point where brands must break through the chaos of shifting news cycles and cultural moments. This means brands have to consistently produce content that positively sways consumer opinion—and they can’t afford to allocate budget on campaigns that miss the mark.
Yet, many teams remain hindered by a lack of quality insights: more than 50% of marketers rate their ability to develop high-quality insights as poor, and only 13% rate it as excellent, according to a Lions Advisory study.¹
Swayable’s whitepaper, Proving Persuasion, outlines how global brands are overcoming the insights barrier. They’re moving beyond gut instinct and vanity metrics to measure the true impact of their campaigns with rapid randomized controlled trial (RCT) methodology and AI-powered insights grounded in human measurement.

The concept of measuring persuasion has existed since the 1990s, when measurement firms
introduced brand lift studies. At the core of these studies were RCT experiments: quantitative surveys that definitively proved shifts in consumer opinion. These experiments enabled marketers to gauge the reactions of consumers randomly selected to view certain ads versus those who weren't.
In the context of today’s digital media ecosystem—where cultural trends and consumer opinions shift constantly—there are clear limitations to traditional lift studies:
By AI-powered creative testing, grounded in real consumer responses, brands can now generate evidence of brand lift in as little as 24 hours. This gold standard for creative pre-testing allows marketers to validate any concept—from ad mockups to brand refreshes—at any stage of development.
