A/B Testing
Yes — A/B testing is a core tactic in Lead Gen.
It happens primarily in Stage 1: Target & Outreach (and inbound channels feeding it).
Goal: Maximize meetings booked per dollar/effort spent.
Where A/B Testing Fits in Lead Gen
| Lead Gen Channel | What You A/B Test | Example | KPI to Improve |
|---|---|---|---|
| Cold Email | Subject line, opener, CTA, send time | “Quick question” vs “[Name], saw your post on X” | Open rate → Reply rate → Meeting |
| LinkedIn Messages | Connection note, 1st message, follow-up | Personalized vs template | Accept % → Response % |
| Paid Ads (Google/FB/LinkedIn) | Ad copy, image, headline, landing page | “Free Audit” vs “Grow SQLs 3x” | CTR → Cost per SQL |
| Landing Pages / Lead Magnets | Headline, form length, offer, social proof | Ebook vs Checklist vs Audit | Conversion rate (form fill) |
| Webinars / Events | Title, time, speaker, promo channel | “Live SEO Teardown” vs “2026 Trends” | Registration → Show-up rate |
A/B Testing Flow in Lead Gen (Stage 1)
1. Hypothesis → “Personalized subject lines > generic”
2. Build 2 variants (A vs B)
3. Split audience 50/50 (same ICP, time, channel)
4. Run for statistical significance (~100–200 sends per variant)
5. Measure → Reply rate / Meeting booked
6. Winner → Scale. Loser → Kill or iterate.
Real Startup Example
| Test | Variant A | Variant B | Winner | Impact |
|---|---|---|---|---|
| Cold Email Subject | “Growth ideas for [Company]” | “Quick question” | B | +180% reply rate |
| LinkedIn CTA | “Let’s chat” | “Free 15-min audit” | B | +2.3x meetings |

TL;DR:
A/B testing in Lead Gen = testing every touchpoint in Stage 1
→ Cold emails, ads, landing pages, CTAs
→ Goal: More Stage 2 (Discovery Calls) per $ spent
