Voice of Customer
Voice of Customer (VoC)
In one line
Voice of customer (VoC) is the systematic practice of gathering and analysing customer feedback — reviews, interviews, surveys, support tickets — and feeding it back into product and marketing decisions.
Going deeper
VoC is the practice of treating customer language as data — the open text behind an NPS score, interview transcripts, review-site comments, support tickets, social mentions. Anything where the customer chooses the words counts as VoC.
It matters in marketing because conversion rates almost always rise when copy uses the customer's actual phrasing. The lift between conference-room copy and copy lifted from VoC tends to land at 20% or more in head-to-head tests.
Under GEO, VoC matters even more. A lot of what AI cites about your brand comes from third-party reviews and community posts, so VoC has shifted from an internal insight tool toward an external reputation discipline.
