The #ad hashtag significantly improved young adults' recognition of sponsored e-cigarette posts on social media compared to #sponsored. This highlights the effectiveness of clear disclosures in identifying commercial content online.
Area of Science:
- Public Health
- Social Media Research
- Consumer Behavior
Background:
- Most e-cigarette social media content originates from sponsored influencers, not authentic user posts.
- Effective disclosure strategies are needed to ensure social media users recognize commercial sponsorship.
Purpose of the Study:
- To evaluate the effectiveness of different disclosure hashtags (#ad vs. #sponsored) in informing young adults about commercially sponsored e-cigarette content on Instagram.
- To assess the impact of visual attention on recognizing sponsored posts.
Main Methods:
- Young adults (16-24) viewed manipulated Instagram feeds with e-cigarette influencer posts labeled #ad or #sponsored.
- Eye-tracking software measured visual attention to hashtags, and participants self-reported their interpretations.
- Logistic regression and qualitative content analysis were used to analyze recognition and themes.
Main Results:
- The #ad hashtag was associated with nearly double the odds of recognizing commercial content compared to #sponsored.
- Increased attention to disclosure hashtags significantly raised the likelihood of commercial recognition.
Conclusions:
- The #ad disclosure effectively captures attention and enhances young users' recognition of commercial sponsorship on social media.
- Clear labeling of sponsored social media content is a viable strategy to improve user awareness of influencer marketing.

Vapor Pressure Lowering
Dissolving a nonvolatile substance in volatile liquid results in a lowering of the liquid’s vapor pressure. This phenomenon can be explained by considering the effect of added solute molecules on the liquid's vaporization and condensation processes. To vaporize, solvent molecules must be present at the surface of the solution....
