Voice of customer (VoC) mining for agencies: a repeatable client workflow
Agencies win pitches with insight the client doesn’t already have. Voice-of-customer mining — pulling the exact words buyers use from reviews — gives you that insight for every account, without a research budget. Here is the workflow, the deliverables and how to package it as a retainer.
The short answer
- VoC mining extracts the exact phrases customers use about a problem, so your copy sounds like the buyer, not the brand.
- Competitors’ 1★–2★ reviews are the fastest VoC source for agencies: public, current and full of switching language.
- Deliver it as a phrase bank, pain themes with proof and ready-to-test ad angles — then refresh it monthly.
- On ChurnMine, an audit takes about a minute; Agency Pro makes audits unlimited and white-label client links carry your brand.
What VoC mining is — and why agencies should own it
Voice-of-customer mining is collecting what customers say in their own words — reviews, tickets, calls, forum posts — and organising it into themes, phrases and emotions you can reuse in positioning and copy.
For agencies it solves a recurring problem: clients rarely hand over customer research, and interviews take weeks. Competitor reviews are a public substitute available on day one of an engagement. The competitors’ unhappy customers describe the exact pains your client wants to win on.
- Pitches: open with three verbatim complaints about the prospect’s biggest competitor.
- Messaging: rewrite headlines using phrases buyers actually typed.
- Paid social and search: test angles built on the most common churn trigger.
- Retention: show the client which pains they must never copy.
The agency VoC mining workflow, per client
- 01
Map the competitive set
Ask the client for the 3–5 tools they lose deals to, and confirm with G2 compare pages and “alternatives” searches.
- 02
Mine low-star reviews per competitor
Run one audit per competitor on the review source their buyers use. Use paste or CSV for Reddit threads or the client’s own support tickets.
- 03
Build the phrase bank
Collect recurring phrases with the emotion behind them — frustration, betrayal, anxiety — and where each belongs: headline, ad hook, objection handling.
- 04
Rank pain themes
Order themes by share of reviews and switching intent across all competitors. The top two become the campaign pillars.
- 05
Draft angles and assets
One ad angle per pillar, a short cold email, and a battlecard for the client’s sales team.
- 06
Package and present
Send a branded report link or PDF, then schedule a monthly refresh to catch new complaints.
What to deliver to the client
1. A VoC phrase bank
The 15–30 phrases that recur, each with the emotion behind it and a suggested use. ChurnMine’s phrase bank lists frequency, context and a “use it for” note per phrase.
2. Pain themes with proof
Three to six themes with share of reviews, switching intent and two verbatim quotes each — the evidence that makes a client trust the recommendation.
3. Ad angles and a cold email
Hooks for Meta, Google Search and LinkedIn that lead with the pain rather than the competitor’s trademark, plus an outbound email under 75 words.
4. A sales battlecard
Us vs. Them by dimension, with evidence, a positioning line and objection handlers for the client’s reps.

Phrase bank — new phrases this month highlighted 4. Recommended tests — three ad angles, one email, one landing-page headline 5. What changed since last month
Example: a VoC brief for an email-marketing client
Say the client is an email platform competing with Mailchimp and Klaviyo. Two audits give you the brief:
Unresponsive, Unhelpful Support
“Customer service Zero. Warning, this was a super respectable tool for so many years but totally went down in both performance and support level. Stay away!”
Poor Customer Support
“Putting the customer support behind a paywall is appalling! And only when my plan runs out does it start to have unresolvable issues that require support.”
Mailchimp’s top trigger is “Unresponsive, Unhelpful Support”; Klaviyo’s is “Poor Customer Support”. Where the two competitors share a pain, you have a pillar for the whole category. Where they differ — “Hidden Costs & Billing Issues” versus “Aggressive Billing & Overcharging” in second place — you have competitor-specific proof for the sales team.

Package VoC mining as a retainer, not a one-off
VoC mining compounds. Competitors change pricing, support degrades and new alternatives appear; agencies that refresh monthly catch these shifts before the client’s sales team does.
- Pitch: a free one-competitor preview as the opener — score, #1 pain and verbatim quotes.
- Onboarding: the full competitive set, phrase bank and first campaign pillars.
- Monthly: refresh each competitor, highlight new complaints and send a white-label report link.
- Quarterly: a battlecard review with the client’s sales team.
On Agency Pro, audits are unlimited and white-label client links carry your agency’s logo, colour and name — with “Powered by ChurnMine” removed.
