A scalable lead generation engine that outpaces the rigid structures of legacy competitors. Performance marketing as a business utility, calm, intentional, undeniably effective.

Volatility in the gap and dental cover markets

South Africa's niche insurance sector is notoriously competitive, fluctuating cost-per-acquisition and high volumes of low-intent leads that often burden internal sales teams. For Zestlife, a leader in gap and dental cover, the objective was not just to increase lead volume, but to achieve a state of predictable excellence: consistent lead flow paired with high conversion probability.

Zestlife asked us to drive its Google Ads on a performance-driven contract, with a cost-of-sale target.

Precision over proximity

NightJarr shifted focus from broad-match reach to a machine-learning-led approach anchored in conversion data integrity. Recognising that "more" is not always "better", we implemented a rigorous Google Ads strategy built on three pillars:

Machine-learning calibration

By refining conversion tracking and importing offline conversions, we provided Google's bidding algorithms with cleaner signals, allowing the system to distinguish casual browsers from high-intent applicants.

Operational consistency

In a high-interest-rate environment where consumer behaviour shifts rapidly, we maintained a steady hand on campaign management, preventing the aggressive peaks and troughs typical of less disciplined performance marketing.

ROI tracking

A Google Data Studio dashboard visualised lead and sales data end-to-end, so spend, lead quality and revenue could be read at a glance and decisions made on evidence, not instinct.

What we delivered

Five workstreams ran in parallel across the engagement.

  • Conversion tracking rebuild, GA4 + GTM remediation, server-side tagging where signal loss was material.
  • Offline conversion imports, CRM-to-Ads pipeline so qualified-lead and sale signals fed bidding directly.
  • Smart bidding migration, phased move to cost-per-sale bidding with guardrails.
  • Search-term & audience hygiene, continuous pruning of low-intent traffic.
  • Reporting cadence, weekly summaries; monthly review with the sales desk.
  • Audience-signal tuning per product line, gap vs. dental cover treated distinctly.

Performance as a constant.

Over the past 24 months, the collaboration has transformed Zestlife's digital acquisition into a stable, high-performing asset.

Stable baseline volume

Consistent flow lets Zestlife forecast sales capacity and resourcing with high accuracy.

Higher conversion ratio

Deliberate optimisation of search queries and audience signals, sales-desk efficiency directly improved.

Scaled through volatility

Held performance steady through interest-rate shifts and regulatory nuance.

“NightJarr has delivered predictable sales growth for us during the last 2 years.”
