A Quarter of Efficient Lead Generation for an ISP

Client  Fiberstream — regional fiber internet provider (under GMEDIA) Role  Performance Marketing — strategy, build, optimization Period  Jan 2025 – Mar 2025
2,500+ Qualified leads in Q1 2025
12–15% Click-through rate sustained
1.4M+ Ad impressions delivered

Ran a full quarter of Click-to-WhatsApp acquisition for an ISP where every sign-up needs a human close — sustaining double-digit CTR and a steady flow of qualified leads across four cities on a lean budget.

The problem

An ISP can’t be bought online instantly: the funnel runs ad → website click → WhatsApp enquiry → human close by the CS team. That hand-off makes naive ROAS meaningless, so success had to be defined by lead efficiency and the cost-quality of each conversation generated.

Strategy

  1. Built Click-to-WhatsApp (CTWA) campaigns across Google and Meta so every ad spend drove a trackable conversation, not just a click.
  2. Segmented campaigns by service area — Jogja city, Jogja outskirts, Solo, and Purwokerto/Pemalang — to isolate where intent actually converted.
  3. Optimized for cost per qualified lead and click-to-conversion rate rather than vanity reach.

Execution

  • Delivered 1.4M+ ad impressions across the quarter while holding click-through rate in the 12–15% range.
  • Ran continuous creative and copy A/B tests to defend CTR as competition and fatigue increased.
  • Mapped the post-click funnel (landing page → WhatsApp form → CS follow-up) and tightened drop-off points with the CS team.
  • Reviewed city-level performance monthly and concentrated budget on the most efficient areas (Jogja outskirts and Solo), flagging weaker markets for evaluation.

What I took away

When the close is human, the marketer’s job is to deliver the cheapest possible qualified conversation and engineer the hand-off — not to chase attribution it doesn’t own. City-level segmentation turned a flat budget into a sharper, more efficient one.
