Creative Testing Matrix (Example)

Teardown: Real B2B CPL Optimization (Before/After)

// TODO: Insert a before/after table: Generic setup vs. optimized setup, with results (CTR, CPL, pipeline)

  • Before:
    • Targeting: "Marketing" + "UK" (audience: 500,000+)
    • Offer: "Learn More"
    • Creative: Stock image, generic copy
    • Landing Page: Homepage
    • Result: £320 CPL, 0.3% CTR, no pipeline
  • After:
    • Targeting: Account list (200 companies) + "Head of Marketing" + "Director+"
    • Offer: "Free 2025 ROI Calculator (Excel)"
    • Creative: Pain-first headline, real testimonial, bold CTA
    • Landing Page: Single-purpose, proof above the fold
    • Result: £95 CPL, 0.9% CTR, 4 pipeline deals in 30 days

Troubleshooting: If Your CPL Is Still High

  • Targeting too broad or vague: Tighten with job title, function, and account list.
  • Creative fatigue: Refresh every 2 to 3 weeks, test new hooks.
  • Landing page leaks: Use Hotjar, simplify, add proof, remove distractions.
  • Offer too generic: Test a "no-brainer" offer (audit, calculator, demo).
  • Tracking not set up: Verify Insight Tag and conversion actions.
  • Still stuck? See Troubleshooting Playbook.
