SEO article writing
Produce a complete SEO article (1500-3000 words) that ranks in the top 10 on a target query, while maintaining the editorial quality required by Google's Helpful Content Updates.
Writing a high-performing SEO article traditionally takes 4 to 8 hours: SERP research, competitor analysis, structured plan, writing, NLP optimization, proofreading. AI lets you drop to 1h30-2h for equivalent quality — provided you don't settle for "write me an article on X". This guide details the 5-step workflow that passes Google's Helpful Content filters: SERP analysis by AI, structured brief, section-by-section writing, human enrichment, NLP optimization. The winning ratio: 60% AI, 40% human.
Step-by-step workflow
Analyze the SERP with a research AI
Before writing a line, understand the intent. Use Perplexity or Frase to extract: questions answered by top 10 results, main semantic entities, angles not covered by competitors. That gap is your differentiation.
Write a structured brief
A good brief contains: target query + variants, search intent (informational/transactional), precise audience, H2/H3 plan, entities to include, unique editorial angle, target length, tone and examples to imitate. The brief determines quality — AI doesn't invent, it applies.
Write section by section, not all at once
Asking for a complete article in one go gives uniform and generic content. Have AI write H2 by H2: better density, better consistency, possibility to refine section by section. Claude excels for lengths >1500 words; ChatGPT-5 for shorter and punchier content.
Enrich with your human expertise
This is the step that makes the difference in SEO 2026: add E-E-A-T elements that AI can't invent. Anecdotes, original data, screenshots, sourced quotes, customer feedback, opinions. Aim for 30-40% non-AI content in the final output.
Optimize NLP and proofread
Run the article through Frase or NeuronWriter to verify semantic entity coverage (you gain 5-15 coverage points on average). Then final proofreading in Grammarly + human proofreading for tone, fluency and removal of AI tics ("it's important to note", "furthermore", "let's dive into...").
Copyable prompts
3 tested and optimized prompts. Adapt the bracketed variables [VARIABLE] to your context.
SEO brief from a target query
You are an SEO and content strategy expert. For the target query "[QUERY]", produce a structured writing brief containing: 1. **Main search intent** (informational / commercial / transactional / navigational) + secondary intents 2. **Target audience**: precise profile (role, expertise level, problem to solve) 3. **Article plan**: H1 + 6-8 H2s + main H3s, in logical order 4. **Semantic entities** to include mandatorily (10-15 entities related to the query) 5. **People Also Ask questions** to integrate in a FAQ 6. **Unique editorial angle**: what will make this article better than the current top 3? 7. **Target length** in words and **paragraph structure** (short / medium / long) 8. **Main call-to-action** at the end Be precise and actionable, not generic.
Writing an H2 section
You are a senior SEO writer, clear and expert tone but not pedantic. Write ONLY the H2 section below for an article on "[ARTICLE TOPIC]", aimed at [AUDIENCE]. H2 to write: "[H2 TITLE]" Constraints: - 250-400 words - 2-3 H3 subsections if relevant - Naturally include entities: [ENTITIES] - Short sentences (15-20 words on average), short paragraphs (3-5 lines max) - Tone: [INFORMATIVE / EXPERT / FRIENDLY / TECHNICAL] - NO AI tics: no "it's important to note", "let's dive into", "furthermore", "that said" - No introduction announcing content, get right into the topic - Include 1 number, 1 concrete example or 1 verifiable source Only write this section, no general intro or conclusion.
Optimized PAA FAQ
Generate a FAQ of 5-7 questions for an article on "[TOPIC]". Constraints: - Each question matches a real search (natural phrasing, not marketing) - Answers of 60-100 words, direct and useful - No generic filler, each answer brings concrete info - Format compatible with FAQPage schema (short questions in H3 or strong, answers in paragraph) - Mandatorily include if relevant: pricing, alternative, comparison, duration, prerequisites - Avoid redundancy with article body

Frequently asked questions
Can a 100% AI article rank well on Google?
Very rarely and less and less. Since the March 2024 Helpful Content Update and its iterations, Google increasingly detects raw AI content (style uniformity, lack of concrete expertise, absence of original data). Mixed AI + human content done well performs; purely AI articles now risk downranking.
How much time does AI really save in SEO writing?
On average 60-70% on raw production time, but net gain depends on quality requirements. For a quality SEO article: 4-8h pure human → 1h30-2h with AI well used. For a "just published" article without quality: 2h → 15 minutes, but won't rank.
What is the best LLM for long-form writing?
Claude has dominated long-form writing benchmarks since 2024: better structure, fewer repetitions, better follows detailed briefs. ChatGPT-5 has closed part of the gap in 2025 and remains excellent for shorter and punchier content. Jasper stands out in marketing-team context with codified brand voice.
Can AI replace a web writer?
For standardized and factual content (product sheets, descriptions, generic FAQs): largely, yes. For high E-E-A-T editorial content (reviews, tests, analyses, experience reports): no, it remains an assistant. The job evolves: less raw production, more strategy, brief, expertise and validation.
