SEO Writing Guide: How to Write Content That Ranks and Converts
Most SEO writing advice focuses on keyword density and word count. That misses the point entirely. Google's goal is to rank the most helpful, relevant content — not the most optimised. Here's how to write for both.
Start with Search Intent Analysis
Before writing a word, understand why someone searches your target keyword. Google classifies intent into four types:
| Intent | What the searcher wants | Content format |
|---|---|---|
| Informational | Learn something | Guide, tutorial, explainer |
| Navigational | Find a specific site | Brand/product page |
| Commercial | Research before buying | Comparison, review, best-of list |
| Transactional | Buy or sign up | Product page, landing page |
How to identify intent: Google the keyword. The top 5 results tell you what Google believes the intent is. If all top results are step-by-step guides, write a step-by-step guide. If they're listicles, write a listicle.
Mismatching intent is the most common reason well-written content fails to rank.
Analyse the Top Results Before Writing
Spend 20 minutes studying the top 3–5 ranking pages for your keyword:
- What format do they use? (guide, list, table, FAQ, comparison)
- What subtopics do they cover? (these are your required sections)
- What angle or unique perspective could you add?
- What questions do they leave unanswered? (your opportunity)
Use tools like Ahrefs or SEMrush to see which keywords those pages also rank for — these are your secondary keywords to weave in.
Structure Your Article for Scannability
Most readers don't read — they scan. Structure your content so skimmers get value and readers get depth.
The Right Heading Hierarchy
H1: Primary keyword + clear benefit (page title)
H2: Major section (secondary keyword)
H3: Subsection or specific point
H2: Another major section
H3: Specific point
H2s should stand alone. A reader should understand the article's structure just by reading the H2s.
Optimal Paragraph Length
- Body paragraphs: 2–4 sentences
- Maximum: 5 sentences before a line break
- Use bullet points and numbered lists for scannable information
- Use bold for key terms and concepts (not for decoration)
The Introduction Formula
Your intro has one job: convince the reader they're in the right place. Use this structure:
- Hook — a surprising statistic, a counterintuitive statement, or the reader's exact pain point
- Empathise — acknowledge the problem or goal
- Promise — what they'll learn or achieve by reading
- Credibility signal (optional) — why you/the site is qualified to answer
Length: 50–150 words. Don't bury the lede.
Keyword Placement Strategy
You don't need to hit a keyword density percentage. You need to use your target keyword where Google pays most attention:
| Location | Importance | Notes |
|---|---|---|
| H1 (title tag) | Critical | Include exact match |
| First 100 words | High | Natural, not forced |
| H2 headings | High | Use variations, not exact repeat |
| Image alt text | Medium | Describe image + keyword if relevant |
| URL slug | Medium | Short, keyword-only slug |
| Meta description | Low for ranking | High for click-through rate |
Latent Semantic Indexing (LSI) and Related Terms
Google understands topics, not just keywords. Use related terms naturally:
- If writing about "email marketing": list building, open rate, subject lines, drip campaigns, segmentation
- If writing about "link building": backlinks, anchor text, domain authority, outreach, guest posting
Ahrefs' "Also rank for" report or the "People also ask" box in Google reveals these related terms.
Writing for Featured Snippets
Featured snippets (position zero) appear above all organic results. Win them by:
Paragraph snippets: Answer the target question directly in 40–60 words, immediately after an H2 that mirrors the query.
## What is anchor text?
Anchor text is the visible, clickable text in a hyperlink. Search engines
use anchor text to understand what the linked page is about. Descriptive
anchor text (like "keyword research guide") is more valuable for SEO than
generic text like "click here" or "read more."
List snippets: Use a numbered or bulleted list to answer "how to" or "best X" queries.
Table snippets: Use markdown tables for comparison queries.
The Content Upgrade: Going Deeper Than Competitors
Longer isn't always better — more useful is. Ways to add depth:
- Original examples — don't just describe, show
- Step-by-step screenshots — reduces reader effort
- Case studies — real results beat generic claims
- Downloadable resources — checklist, template, spreadsheet
- Expert quotes — adds credibility and unique perspective
- Updated data — reference the most recent statistics available
The question to ask about every paragraph: "Does this make the article more useful, or just longer?"
After Publishing: Optimise Based on Data
Publishing is the beginning, not the end. After 3–6 months:
- Check GSC — what queries does the page rank for? Add sections addressing high-impression/low-click queries
- Check scroll depth in GA4 — where do readers drop off? Rewrite or move those sections
- Update stale statistics and dates — "Updated [Year]" in the title can lift CTR significantly
- Add internal links — link newly published articles to this page from relevant anchor text
Content that gets refreshed annually consistently outperforms content that's published and forgotten.
SEO Writing Checklist
Before publishing every article:
- Search intent confirmed (format matches top results)
- Primary keyword in H1, first 100 words, and at least one H2
- Secondary keywords and related terms used naturally
- Every H2 can stand alone and describes the section clearly
- Introduction under 150 words with a clear promise
- Paragraphs ≤ 4 sentences
- At least one featured snippet opportunity written in (paragraph or list)
- Internal links to 3–5 related articles
- Meta description written (includes keyword + CTA)
- Images have descriptive alt text
