Far More People Actually Become Customers
People who are referred by a friend are not just slightly more likely to become customers, they are dramatically more likely. Traditional ads struggle to get past single digits, while warm referrals reliably hit double digits.
Better Customers, Not Just More Customers
Referrals don't just bring in more people, they bring in better ones. Research from Wharton Business School and other institutions shows that customers who came through a friend are more valuable from start to finish.
Each New Customer Costs You Much Less
Every pound you spend on referrals works harder. Because referred people are quicker to say yes and stay longer, the cost of winning each new customer drops a lot compared to paid ads.
