Content Agencies & Bloggers

    English Content Writer – Keyword Automation

    A multi-stage AI system that turns a single keyword into a full SEO-optimized article using SERP research and iterative refinement.

    Problem Statement

    Producing SEO-optimized blog articles usually takes hours and requires: Detailed SERP research, Identifying top-ranking content formats, Understanding search intent, Extracting subtopics, Writing drafts, Optimizing for SEO, Editing for tone and clarity, Preparing final publish-ready text. For businesses and solo creators, this process is slow, inconsistent, and dependent on SEO knowledge. They needed a system that could take one keyword and produce a well-researched, fully optimized article without human effort.

    The Solution

    Automation Overview

    We built a complete keyword-to-article automation that performs SERP research, extracts ranking patterns, identifies winning content angles, writes the article in multiple AI stages, runs SEO quality checks, revises the article based on scoring, stores output automatically, and logs any errors for debugging. All inside a single n8n workflow.

    SERP Research via Google Serper API

    The workflow starts by fetching the top search results for the given keyword. It extracts titles, meta descriptions, ranking URLs, content snippets, related searches, and People Also Ask questions. This gives the system a clear understanding of search intent and current competitors.

    AI Trend & Angle Identification

    A dedicated AI Analyst (Gemini/OpenAI) analyzes the SERP dataset and identifies common content angles, searcher expectations, gaps competitors missed, subtopics that must be covered, and ideal content structure for ranking. This step mirrors the thought process of an experienced SEO strategist.

    Multi-Stage Drafting Process

    Instead of generating one-shot articles (which are usually weak), the workflow uses a structured, multi-phase writing approach: Phase 1: Outline Creation (AI generates a complete SEO-optimized outline), Phase 2: Section-by-Section Draft Writing (Each section is written individually for clarity and depth), Phase 3: Coherent Article Assembly (All sections merge into one polished article). This ensures higher quality, better coverage, and more natural writing.

    Automated SEO Quality Score

    After drafting the article, another AI agent performs a keyword density check, title & H1 evaluation, readability improvement suggestions, and gap detection (what SERP winners included that the draft lacked). A score and feedback list are generated.

    Revision Loop

    Based on the SEO score, the workflow revises sections, fixes missing elements, strengthens competitor-required content, and improves clarity, tone, and structure. This creates a final version that is SEO-ready and publication-ready.

    Clean Output Storage

    The final, polished article is stored as a document, linked to the workflow, logged for future edits, and organized by keyword theme. This allows teams to build large content libraries with minimal effort.

    Error Logging System

    If any stage fails (e.g., bad SERP results, AI issue, formatting mismatch), the system logs the keyword, captures the error, and records details in a Google Sheet. This makes it easy to debug and rerun only the affected items.
