Post type
What is a blog outline?
A blog outline is a structured plan for your article that organizes your main points, subpoints, and flow before you start writing. It consists of H2 headings (main sections) and H3 subheadings (supporting points) that create a logical hierarchy for both readers scanning the page and search engines parsing the structure. Every high-performing blog post starts as an outline — the writers who skip this step end up with unfocused, hard-to-skim posts that bury the value and underperform in search.
This free blog outline generator gives you six different intent-based templates (how-to, listicle, comparison, case study, definitional, pillar) — each calibrated to the search behavior people display when they Google that type of content. Pick the right template, generate, then edit any heading or subheading inline. Each section includes a target word count so you can hit the right depth for SEO.
The six post types and when to use each
| Post type | Best for | Typical length |
|---|---|---|
| How-to / Tutorial | "How to X" searches; step-by-step content | 2,000-3,500 words |
| Listicle | "Best X", "Top X", "X tips" searches | 1,800-3,000 words |
| Definitional / 101 | "What is X?" awareness-stage searches | 1,500-2,500 words |
| Comparison (X vs Y) | Decision-stage searches; head-to-head reviews | 2,500-4,000 words |
| Case study | Credibility + narrative; trust building | 2,000-3,500 words |
| Pillar / Complete guide | SEO authority hub; ranking for broad terms | 3,500-6,000+ words |
Why outline before you write
- Prevents writer's block. You always know what the next section is supposed to cover.
- Ensures comprehensive topic coverage. A good outline reveals gaps before you've invested 2 hours writing around them.
- Creates a logical flow that retains readers. Reorganizing 12 paragraphs is a chore; reordering 8 section titles is 30 seconds.
- Helps you estimate length and effort. Each H2 with subheadings = ~200-500 words. Multiply for total target.
- Improves SEO. Search engines reward well-structured content with clear heading hierarchy. Featured snippets often pull from a single H3 paragraph.
- Enables collaboration. Hand a freelancer or AI assistant an outline + word targets and you get back a draft you can ship, not one you have to rewrite.
Ideal blog structure for SEO (and humans)
| Section | Purpose | Typical length |
|---|---|---|
| Introduction | Hook the reader, state what they'll learn, include the keyword in first 100 words | 150-250 words |
| H2 sections (4-8) | Main points with keyword variations in headings | 250-500 words each |
| H3 subsections (2-4 per H2) | Supporting details, examples, data, screenshots | 100-250 words each |
| Tables / lists | Scannability + featured-snippet targets | 1-2 per post |
| FAQ section | Long-tail keyword coverage + voice search | 200-500 words |
| Conclusion + CTA | Summarize key takeaways, clear next action | 100-200 words |
How to customize a generated outline for your audience
- Generate using the closest-match post type.
- Click the pencil icon on any heading to edit it inline.
- Replace generic subheadings ("Subheading 1") with topic-specific phrases that match your audience's vocabulary.
- Add or remove sections via the + and × buttons. Most posts benefit from cutting 1-2 sections, not adding more.
- Make sure your primary keyword appears in 1-2 H2 headings, not all of them — over-optimization is a flag.
- Copy as Markdown (for Notion, Obsidian, GitHub, dev docs) or HTML (for direct CMS paste).
Frequently Asked Questions
How many H2 headings should a blog post have?
Most well-performing blog posts have 4-8 H2 headings. This provides enough structure for both readability and SEO without fragmenting the content into sections too short to be useful. Pillar content can have more (8-12); how-to posts often have fewer (4-6). Pay attention to depth-per-H2: if you have 2 sentences per H2, merge sections; if you have 800 words, split.
Should I include my keyword in every heading?
No. Include your primary keyword in the H1 (title), 1-2 H2 headings, and the first 100 words of body content. Use semantic variations (synonyms, related terms) in other H2s. Stuffing the same keyword in every heading reads as spam to both readers and Google's algorithm and can trigger penalties.
How long should a blog post be in 2026?
It depends on the post type and search intent. Tutorials and pillar guides perform best at 2,500+ words. Definitional posts and listicles work well at 1,500-2,500 words. Comparison posts often need 3,000-4,000 words to do justice to multiple options. Most importantly: match the length of currently-ranking results for your target keyword. Use a SERP analyzer or just check the top 5 results.
Can I customize the generated outline?
Yes — every heading and subheading is editable inline. Click the pencil icon to edit, the X to remove a section, and the + to add new ones. Reorder by editing the array in your final document. The generated outline is a starting point — your real value as a writer is in the specific sub-subheadings, examples, and angles that only you (or your industry expertise) can provide.
What is the target word count per section?
Each section's target is a rough guide based on what we've seen perform well — typically 200-500 words for primary sections, 100-300 for sub-sections. The total at the top adds these up for your overall target. Adjust to your audience: technical readers want depth (lean longer); executive audiences want brevity (lean shorter).
Is this tool using AI?
No — it uses six handcrafted intent-based templates, each with realistic section structures derived from analyzing top-ranking posts in that format. The advantage: instant, unlimited, no API costs. The tradeoff: the templates are starting points — you should edit headings to reflect your specific angle, audience, and keyword research. For AI-generated topic-specific outlines, try Quillly.
