Diploma enquiries only matter if they turn into counsellor calls and enrolments, not just form fills. Mumbai students also strongly prefer WhatsApp to long forms.
Our approach
- Search campaigns on high-intent diploma keywords.
- Performance Max with a WhatsApp-first conversion path for mobile users.
- Weekly review of cost per lead by channel, cutting underperforming ad sets fast.
Takeaways
- WhatsApp converts cheaper than forms for this audience — ₹30 vs ₹1,151 per lead.
- A single well-targeted campaign can return many times its spend through one enrolment; don’t judge lead campaigns on cost-per-lead alone.
