How word of mouth community hotspots turned neighbour talk into measurable growth
Acquisition costs were climbing. Multi box discounts were squeezing margin. Traditional media was losing cut through. Instead of shouting louder, Abel & Cole needed to focus spend on places where word of mouth was already doing the convincing.
The goal wasn't just to find new customers but to reach the right customers.
"Herdify’s community targeting insights improved response rates for our door drop campaigns by 164%.” ~ Abel & Cole
Detecting where word of mouth is strongest
Able and Cole with their media agency, Join the Dots, used Herdify’s Behavioural Segmentation Engine to analyse first-party data and spot postcode clusters where real-world word of mouth was already active. Not social lookalikes. Actual communities where boxes on doorsteps spark neighbour chat, school-gate mentions, and kitchen-table recommendations.
Targeting customers who already care
We dropped those postcodes straight into the door drop plan. Creative mirrored what people were already seeing locally, so Abel & Cole felt familiar and trusted before the leaflet even landed.
Nudge momentum
The job was not to create interest from scratch. It was to give a gentle prompt where word of mouth had primed the decision.
The Numbers
- The average door drop response rate in areas with detected Abel & Cole brand communities was 168% higher than in areas where no communities were detected
- The average order value was 6.8% higher in areas with detected Abel & Cole communities
- The average number of box purchases required to see a positive customer acquisition cost decreased by 30%
Cut waste by planning into advocacy
Focusing on advocacy hotspots let Abel & Cole spend less to achieve more.
- Right size print and coverage to match advocacy hotspots, not blanket the map
- Shorten the path to response because social proof is already visible on the street
- Localise creative lightly so it reflects what people already see, while keeping the core offer consistent
Apply the advocacy map across channels
Once you know where word of mouth concentrates, you can point more than mail at it.
- Door drops and inserts to convert primed households
- OOH and local press where social proof already lives
- Paid social and search budgets weighted to hotspot postcodes
- Field, sampling, partnerships in communities that already care
Use social proof you can see
People copy local behaviour. When a leaflet arrives where boxes are already on doorsteps, the message is not cold. It is a normal next step that fits what the street is doing.
How you can run this
Here is the simple way brands repeat this outcome.
- Detect hotspots
- Herdify flags advocacy clusters at postcode level using market behaviour signals. No first party data needed.
- Plan into them
- Use your agency to weight door drop and supporting channels to those postcodes.
- Launch with controls
- Run community vs non community comparisons. Measure response, average order value, and speed to payback.
- Scale what works
- Roll the winning postcode list and learning into digital, OOH, and local activity. Refresh the map as behaviour shifts.
