What is the Blog Headline A/B Tester?
The headline is the single most important line in any piece of content. It determines whether the article gets read at all. On average, 80% of people who see a headline don't click — meaning a good headline isn't just nice to have; it's the difference between an article being read and being invisible.
Most writers draft one headline and move on. That's a mistake. The best-performing content usually runs on headlines that follow specific formulas — curiosity gaps, data-driven specificity, contrarian takes, how-to framings — and each formula performs differently depending on the channel and audience.
The Blog Headline A/B Tester gives you ten headline variations, each using a different proven formula, and scores every one across three dimensions: click appeal, SEO value, and shareability. It identifies a winner, but the real value is seeing the full spread — you learn what makes headlines work, and you can pick the style that fits the specific channel (search, social, newsletter).
How It Works
Runs on Llama 3.3 70B via Groq with Gemini and OpenRouter fallbacks. The system prompt encodes ten distinct headline formulas that have been repeatedly validated by content marketers:
1. **How-to** — "How to [achieve X] in [timeframe]" 2. **Listicle** — "[Number] [things] that [outcome]" 3. **Question** — Direct question that speaks to a pain point 4. **Controversial** — Challenges conventional wisdom 5. **Data-driven** — Leads with a specific statistic or number 6. **Curiosity gap** — Opens a loop the reader has to close 7. **Fear-based** — Highlights a risk or consequence 8. **Aspirational** — Paints the desired outcome 9. **Comparison** — "A vs B" framing 10. **Breaking news** — Timely announcement angle
For each headline, the model estimates three scores: click appeal (how likely people are to click in a feed), SEO value (how well the headline matches search intent and keyword patterns), and shareability (how likely people are to send it to a friend or post it). The scores aren't scientific measurements — they're pattern-based estimates — but they're directionally useful.
The tool also delivers a short pro tip at the end, usually a specific technique to improve a headline you're already working with.
Who Is This Tool For?
- Bloggers — Test multiple headline angles before publishing instead of committing to the first one that sounds okay.
- Content marketers — Choose the headline style that fits each channel: SEO-optimized for search, click-focused for social.
- Newsletter writers — Subject lines are headlines; use the tool to test multiple angles.
- YouTube creators — Adapts well to video titles — specify 'video title' and the tool adjusts.
- Freelancers pitching clients — Bring 10 headline options to the conversation instead of 1.
- Anyone trying to improve their headline instincts — Study the scoring to see what makes headlines work across dimensions.
How to Use the Blog Headline A/B Tester
- Enter your topic or a draft headline. Broad topics work: 'How to save money using AI tools.' Specific drafts also work: '7 Ways AI Tools Can Save You Money.'
- Click ✨ Generate. You'll get 10 headlines, each using a different formula, with scores for click appeal, SEO, and shareability.
- Read all 10 before picking. The best headline for a search-driven blog isn't necessarily the best headline for a Twitter share — the tool surfaces the trade-off by scoring each separately.
- Look at the winner and runner-ups. If the winner isn't a fit for your channel, use the second or third — the scores are directional, not absolute.
- Copy your chosen headline and, if applicable, run it through your SEO tool of choice to verify it works with your target keyword.
- Keep the losing headlines. They're useful for social media variants, email subject lines, and video titles for the same content.
