Digital is excellent at reach and frequency. It is weak at smell, texture, dose and “I already tried this.” When you compare media plans are really asking: when is a physical trial worth the logistics?
What the evidence says about sampling
- Arbitron / Edison: 35% of tryers bought the sampled product on the same shopping trip; 58% said they would buy it again (NYT; Marketing Charts)
- EventTrack 2015: 65% purchased what was promoted at the event/visit; 78% of those more inclined to buy credited the chance to try first
- YA / Survata survey (1,000 U.S. adults): 53% often or always buy a product they sampled; 77% said a sample would encourage them to try another product from the same brand
What trial does to purchase
What the evidence says about physical vs digital media
USPS OIG research with Temple University found digital ads were processed faster, but physical ads produced stronger emotional response, better week-later memory, and brain activity associated with product value and purchase intent. The practical reading for brand teams: use digital to get attention quickly; use a kit, guide or other physical touch when you need lasting recall at the shelf.
Physical vs digital memory
Digital
Faster at first glance
Processed quickly — strong for speed and scale.
Physical
Stronger a week later
Longer memory, stronger emotion and purchase-intent signals.
Use sampling when the decision is sensory or habit-forming
- Baby care, food, hygiene, personal care — trial reduces risk
- Life-stage switches (new baby, new school, new campus) reset brand repertoires
- You need a keepsake context (guide + kit), not only a 6-second view
- You want consented first-party data after a real experience
Keep digital — and combine both
Sampling does not replace always-on media. Mondelēz has described increasing investment in sampling while shifting more of the mix toward digitally led tactics, without abandoning in-store experiential trial — and separately investing in first-party data Online Platforms for a cookieless world. SoPost’s 2026 industry outlook makes the same strategic point from the beauty side: consumers want verifiable proof, and brands are pairing digital discovery with physical trial while collecting consented preference data.
If your KPI is “tried and considered,” sampling belongs in the plan. If your KPI is only cheap reach, digital wins on paper — and often loses at the shelf. START exists for teams that need trial in Southeast Europe without building clinic and school networks from scratch.
