We all see them passing by: those AI-written articles. But are they relevant? Do they deliver results for businesses? Do they generate traffic?
The answer: yes. Just like our client Domicil’Gym, you can cut your SEO content production costs by 10x — provided you move beyond ChatGPT and invest in a robust system designed by an AI SEO agency.
When you rely on a single AI assistant (such as ChatGPT or Claude) for complex tasks, the results quickly show their limits: shallow content, generic answers, no real depth. Both your audience and Google’s algorithms can detect it. The output ends up with little added value, sometimes even harming your SEO instead of helping it.
Think of it this way: you wouldn’t expect a CEO to run every single task in a business without delegating to specialized employees. AI works the same way. To achieve strong results, you need a coordinated team — an architecture of specialized agents working together toward a complex goal.
That’s where multi-agent systems (MAS) and custom AI workflows come in. Far beyond standalone chatbots, they enable structured reasoning chains where each agent excels at a finely defined sub-task.
Platforms like RelevanceAI or Aimwork make it possible to deploy these systems. We implemented such a solution for a client who wanted to automate their SEO content production.
Why Use AI Agents for SEO Content Creation?
SEO content is inherently complex. A professional writer or SEO strategist needs to go through many steps before producing content that can compete and rank:
Analyzing the SERP
Benchmarking top-ranking pages
Identifying search intent
Checking latest news and trends
Collecting secondary keywords
Drafting a structured outline
Writing & editing content
…and more.
Asking ChatGPT to “just write an article” skips all of this. Even with a strong prompt, the piece lacks depth, and Google won’t rank it favorably.
But what if each stage was handled by a specialized AI agent? The result: content equal to — or better than — skilled human writers, at 10x less cost.
Our Multi-Agent System for SEO
On RelevanceAI (and similar MAS platforms), the architecture combines two elements: agents and tools.
SEO Agents
In our setup, each agent has memory, autonomy, and a precise responsibility. A central “Manager Agent” orchestrates the workflow, delegating tasks to specialists:
Research Agent: gathers in-depth information on the topic.
SEO Brief Agent: analyzes findings, creating a structured SEO brief.
Writer Agent: produces optimized content aligned with E-E-A-T principles.
Delivery Agent: formats and delivers content via email or Google Docs.
Each agent is structured with:
Role (scope of expertise)
Objective (clear output expectation)
Context (its importance in the full chain)
SOPs (standard operating procedures) to guarantee repeatability
Tools/APIs needed
Defined output format
Critical notes to reduce human QC workload
SEO Tools
Tools are modular functions agents rely on: Google Search scrapers, competitor analysis, keyword clustering, outline generation, writing modules, editing layers, etc.
Each tool:
Accepts a precise input
Executes via dynamic variables
Returns structured output for the next agent in the chain
Orchestrating Models: Choosing the Right Engine
The biggest challenge lies in managing multiple models, as their capacities vary widely.
Fast, low-cost models (ChatGPT 5, Claude Sonnet 4): great for simple tasks, but struggle with nuanced SEO writing or multi-layered instructions.
Advanced reasoning models (o1, DeepSeek R1, Gemini Flash 2.5): better at handling complex tasks, long contexts, and structured output — though more expensive and requiring precise prompting techniques.
Example: after migrating to Gemini 2.5 Pro, one of our clients reduced run-costs to $0.30–$0.50 per complete SEO workflow.

Validation & Quality Control
Every agent output is checked step by step. Our experts validate coherence, factual accuracy, and optimization before passing results along. This ensures errors are caught early and corrected seamlessly.
Workflow vs Multi-Agent: Flexibility & Control
Multi-agent systems (MAS) → flexible, autonomous, powerful for complex tasks like SEO. But results can vary slightly.
Linear workflows → strict, predictable, easier to control, but less adaptable.
In practice, the best SEO automation combines the flexibility of MAS with the control of structured workflows.
Conclusion
Automating SEO content production with AI agents is rapidly becoming the new standard. By breaking down the process into specialized tasks and delegating them to custom workflows, companies can produce high-quality SEO content at 10x lower cost — while freeing human teams for strategy and innovation.
SEO departments will need to evolve. If your company is ready to automate content production with a proven AI-first approach, let’s talk about how we can build your custom system.Ask us for a free trial.
