The problem

A subscription library asks customers to build an ongoing reading habit. The campaign needed to explain the value of membership clearly to customers of an online library serving readers across India.

What we did

  • Make the membership easy to understand. Build creative around reading routines, book selection and membership convenience.

  • Describe the library accurately. Present Libros Library as an online library serving customers across India.

  • Measure paid membership separately. Follow the journey from enquiry to first paid membership so lead volume does not become the only measure of success.

The impact

540 new paid memberships from 2,204 enquiries

Advertising spend of ₹2,16,000 worked out at ₹98.00 per membership enquiry and ₹400.00 per new paid member.

A recreated agency dashboard for Libros Library, Meta Ads, in rupees, June 2025 to March 2026. New paid memberships 540. Advertising spend ₹2,16,000. Enquiries 2,204. Cost per new member ₹400.00. Lifetime value per membership ₹4,800. A membership funnel bar chart compares 2,204 enquiries with 540 new paid memberships. A performance summary shows conversion 24.50%, cost per enquiry ₹98.00 and the supplied lifetime value per membership of ₹4,800.

At ₹400 in advertising cost per new member, the acquisition cost was one twelfth of the supplied ₹4,800 lifetime value. That comparison explains why recurring membership economics matter; lifetime value is not revenue collected during the campaign.

Lead with member acquisition cost and the value of an ongoing membership. Keep lifetime value separate from campaign revenue and ROAS.
