Metric-Driven File Optimization Loop

AUTORESEARCH AGENT: HOMEPAGE COPY OPTIMIZATION

SETUP

Target file: /app/copy/homepage.md

Baseline:
• Current headline: Ship marketing campaigns faster
• Current CTA: Start free trial
• Current conversion: 3.2% (signups / visitors)

Measurement: Google Analytics event signup_click / page_view

Optimization metric: Conversion rate (higher = better)

Iteration limit: 20 attempts, stop if no improvement > 0.1% in last 5 attempts

===== EXPERIMENT LOOP =====

ROUND 1

Baseline metric: 3.2%

Iteration: Edit headline
• Previous: Ship marketing campaigns faster
• New: Get campaign ideas that actually convert
• Reasoning: Benefit-focused, specificity

Commit: git add -A && git commit -m "Experiment: benefit-focused headline"

Evaluate: Run script
→ A/B test deployed
→ 2,000 visitors served
→ Signups: 68 (3.4% conversion)
→ Delta: +0.2pp

Result: PASS (+0.2pp improvement)
→ Keep change (don't reset)

ROUND 2

Baseline metric: 3.4% (new)

Iteration: Edit subheading
• Previous: Less time on setup, more on strategy
• New: 100+ marketers generate campaigns daily. Yours could be next.
• Reasoning: Social proof + urgency

Commit: git add -A && git commit -m "Experiment: social proof subheading"

Evaluate:
→ Signups: 71 (3.55% conversion)
→ Delta: +0.15pp

Result: PASS (+0.15pp)
→ Keep change

ROUND 3

Baseline metric: 3.55%

Iteration: Edit CTA copy
• Previous: Start free trial
• New: See it work (free, 5 minutes)
• Reasoning: Reduce friction (show time commitment)

Evaluate:
→ Signups: 69 (3.45% conversion)
→ Delta: -0.1pp

Result: FAIL (worse)
→ Reset via git reset --hard HEAD~1
→ Discard change
→ Back to 3.55% baseline

ROUND 4 (Agent learns from failure)

Iteration: Edit CTA + subheading together
• CTA: Try free (shorter, past failure informed this)
• Subheading: Join teams cutting campaign setup time by 70%

Evaluate:
→ Signups: 76 (3.8% conversion)
→ Delta: +0.25pp (bigger win!)

Result: PASS (+0.25pp)
→ Keep

===== METRICS AFTER 4 ROUNDS =====

Baseline: 3.2%
Final: 3.8%
Total improvement: +0.6pp (+18.75% relative lift)

Cumulative conversions gained (extrapolated): 200 extra signups/month at 10K monthly visitors

===== AUTOMATION =====

Git-tracked experiments:
• Each round = 1 commit
• Commit message = hypothesis
• Metric = part of commit message (for tracking)

git log --oneline:
• Experiment: social proof subheading (+0.15pp)
• Experiment: benefit-focused headline (+0.2pp)
• Baseline: homepage copy 3.2% baseline

Failure handling:
• If eval script errors → abort round, log error, retry next round
• If metric goes negative (error rate) → git reset --hard, alert

===== WHAT'S BEING OPTIMIZED =====

Each round edits ONE section (or 1–2 related elements):
1. Headline
2. Subheading
3. CTA (copy)
4. Value proposition
5. Social proof
6. FAQ

Agent reasons about each: Social proof helped before, try it on CTA?

===== DEPLOYMENT =====

• Experimental changes deployed to production immediately
• Each variant shown to 5% traffic (95% gets baseline)
• After 2,000 visitors (statistical significance), promote winner or revert
• All wins persist (don't reset to baseline each round)
