3.5.A Paid Acquisition — Ad Testing Framework and CAC Ladder

USER ACQUISITION ENGINE

Creative Testing Framework

Paid social success depends entirely on creative quality. The SPARK creative testing framework runs continuously — every 2 weeks, new creatives are tested against the current control.

Creative Testing Rules:

  • Never run more than 3 creative variants simultaneously per platform
  • Test one variable at a time: hook, format, or CTA — not all three
  • Minimum 3 days of data before declaring a winner (minimum 1,000 impressions per variant)
  • Winning creative becomes the new control. Losing creative is retired immediately.
  • Refresh winning creative every 3–4 weeks to prevent ad fatigue

Creative Hierarchy — What Works for Dating Apps

Creative Type Expected CTR Expected CVR Notes
UGC-style (creator holding phone, authentic reaction) 2.5–4% 4–6% Best performer. Feels organic, not like an ad.
"I tried this app for 7 days" format 2–3.5% 3–5% Strong for TikTok. Authenticity drives installs.
Social proof ("Join 5,000 Bangkok singles") 1.5–2.5% 2–4% Works once brand has credibility. Weak pre-launch.
Polished brand video 0.8–1.5% 1–2% Weakest performer. Looks like an ad. Avoid pre-PMF.
Event recap content 2–3% 3–5% Strong for Phase 3+. Shows real social proof.

CAC Ladder — Scaling Rules

The CAC ladder defines when to increase paid acquisition spend and when to hold. Scaling before the ladder conditions are met wastes budget.

CAC Level Condition to Unlock Spend Level Action
Level 1: Test Any stage $2,000/month Test 3 creative variants. Identify winning audience.
Level 2: Validate CAC below $20, CTR above 1.5% $4,000/month Scale winning creative. Expand to lookalike audiences.
Level 3: Grow CAC below $15, referral rate ≥15% $8,000/month Add second platform (TikTok if Meta is primary, or vice versa).
Level 4: Scale CAC below $10, referral rate ≥25% $15,000/month Full multi-platform campaign. Activate mid-tier influencers.
Level 5: Accelerate CAC below $8, WOM rate ≥30% $25,000+/month Paid ads amplify organic growth. Series A fundraising mode.

SCALING RULE: Never scale paid acquisition before WOM rate is ≥20%. Scaling before WOM is established means you are paying full price for every user. After WOM reaches 20%, every paid user brings 0.2 organic users for free — your effective CAC drops by 20%.

Platform-Specific Strategy

Meta (Facebook + Instagram):

  • Primary audience: Women 25–35, Bangkok, relationship-minded
  • Secondary audience: Men 26–38, Bangkok, professional
  • Best format: Instagram Reels (15–30 seconds), Stories (swipe-up)
  • Bidding: Cost cap at $15 CPR (cost per registration) initially
  • Lookalike: Build from email list of first 500 users

TikTok:

  • Primary audience: Women 22–30, Bangkok
  • Best format: In-feed video, 15–30 seconds, hook in first 3 seconds
  • Creative style: Authentic, creator-style, not polished
  • Bidding: CPM initially, shift to CPA once pixel has 50+ conversion events
  • Best performing hook: "I tried Bangkok's newest dating app for a week..."

LINE Ads:

  • Thailand-specific. LINE is the primary messaging platform.
  • Use for retargeting: users who visited the app store but did not install
  • Best format: LINE News Feed ads, LINE OA sponsored messages
  • Budget: 15% of total paid budget

Paid vs Organic Scaling Rules

Condition Paid Spend Organic Focus
Pre-PMF (Phase 1–2) $2,000–4,000/month 80% of growth effort
Post-PMF, pre-event (Phase 2–3) $8,000–12,000/month 60% of growth effort
Event phase active (Phase 3) $12,000–16,000/month 40% of growth effort
Scale mode (Phase 4) $20,000–30,000/month 30% of growth effort

RULE: Paid acquisition is fuel, not the engine. The engine is WOM + referrals + events. When the engine is running, add fuel. When the engine is not running, adding fuel just burns money.
