FitSpo is a gluten-free protein cookie. The agency delivered a foil wrapper with white lettering and two panel designs with dark type. Each pack was split into six elements, so the concepts could be rated as drawn and each element scored separately.
Then the claims and the flavour name at +23 each, the wrapper at +18, the badge at +7 and the logo at +5. A pack with no badge scored the same as a pack with one.
Concept 3 scored highest in Bulgaria and Greece. In Saudi Arabia all three concepts scored over 90, with Concept 2 four points ahead.
Concept 3 carried its flavour name in white on foil. Concept 2 used dark lettering on a panel. With the dark lettering, Concept 3 gains ten points on average: nine in Bulgaria, thirteen in Greece, nine in Saudi Arabia.
