Copywriting Basics: How to Write Headlines That Convert

By Aurelius X

The Problem

Founders and marketers often make the same headline mistakes: they lead with features instead of benefits, bury the value, or try to be clever at the cost of clarity. The result: low click-through rates, wasted traffic, and poor content ROI. A converting headline does three things—get attention, state value, and compel action.

Who Is This For?

This guide is for founders, content marketers, product marketers, and copywriters who want practical, repeatable headline formulas and a testing checklist they can use right away.

Quick Insights & Analysis

Short research-backed truth: clarity beats cleverness. Readers decide in ~2–3 seconds whether to keep reading. Use clear benefit, urgency, or curiosity with an implied promise. Combine that with a testing habit and you’ll measurably improve conversions.

The Kelstron Headline Framework — 6 Steps to Convert

1. Start with the Audience + Outcome

Who is this for? What will they get?

Example: “For SaaS Founders: Double Trial-to-Paid Conversions in 30 Days.”

2. Lead with a Strong Value Proposition

Swap features for outcomes. Example: “Faster software” → “Ship features 3x faster.”

3. Use Specifics & Numbers

Specifics increase credibility and scannability. Example: “Grow faster” → “Grow ARR by 40% in 6 months.”

4. Add a Trigger — Urgency, Curiosity, or Scarcity

  • Urgency: “Before Q4 ends”
  • Curiosity: “Why 90% of startups miss this metric”
  • Scarcity: “Limited workshop seats”

5. Keep It Readable

8–12 words is ideal. Short enough to scan, long enough to promise value. Mobile-first: keep main clause early.

6. Test, Measure, Repeat

A/B test variants, measure CTR + downstream conversion, and iterate.

Testing & Optimization: A Simple Experiment Template

  • Goal: Improve headline CTR by X% (e.g., +15%).
  • Variants: Create 3 versions: Clear-Benefit, Curiosity, Urgency.
  • Audience: Same audience, same placement (email subject line / landing page hero).
  • Metric: CTR primary; time on page and conversion secondary.
  • Sample size: ~1,000 impressions per variant or 1–2 weeks minimum.
  • Decision rule: If one variant yields statistically significant lift, promote it; otherwise iterate.

Common Mistakes & Fixes

  • Mistake: Being clever but vague. Fix: Ask “What will the reader get?”
  • Mistake: Too many words; bury the value. Fix: Trim to promise + one modifier.
  • Mistake: No test plan. Fix: Always A/B test headline vs. control.
  • Mistake: Ignoring placement. Fix: Tailor to channel (email vs. LinkedIn vs. PPC).
  • Mistake: No matching subhead. Fix: Subhead must validate headline’s promise.

Practical Takeaways

  1. Start with benefit + audience (“For X: Get Y”).
  2. Use numbers and timeframes where possible.
  3. Favor clarity over cleverness.
  4. Keep it mobile-friendly — put value early.
  5. Create 3 variants and test them.
  6. Reuse winning headlines as templates for future campaigns.
