A copywriter tests two headlines: 'Now with 50% more fiber' vs. 'Stay fuller longer and skip the afternoon slump.' Which performs better and why?
-
A
The second, because it describes the customer's lived experience rather than a nutritional specification.
-
B
The first, because specific numbers build credibility and trust with readers.
-
C
The second, because longer headlines always outperform shorter ones.
-
D
The first, because fiber is a well-understood term that needs no translation.
