An SEO AI agent can compare your page against top-ranking competitors, spot what they cover that you don't, and hand you specific recommendations. Once set up, it runs on a schedule with no manual work.
Say your blog post or landing page ranks eighth for its target keyword. The agent pulls your content and the content of the top two ranking pages, analyzes all three against Google's quality signals, and writes its findings straight back into a spreadsheet you control.
What You Need to Build It
The setup uses four components:
- A Google Sheet. One tab holds your focus keyword, your URL, and the URLs of the top two competitors ranking above you. This sheet is both the agent's input and its output.
- n8n. A workflow automation tool, free up to a usage threshold and paid beyond it. n8n is where you build the logic that connects your data, your AI model, and your content-fetching tool into one automated chain.
- An AI model. Any capable model works here. Claude is a strong fit for this kind of content analysis, since the task is close reading and comparison rather than generation.
- Two prompts. One analyzes your content against the competitors' content. The second turns that analysis into a ranked list of recommendations. You can also merge both into a single prompt if you prefer a simpler chain.
How to Fetch the Competitor Content
You have two options for getting content into the agent, and they trade off automation against reliability.
Crawl the URLs directly. In n8n, add a Firecrawl node to fetch live content from each page. This keeps the process fully automated, but you need to confirm the AI is actually reading the page rather than guessing at what's on it. Firecrawl handles most sites well, though it can struggle with pages behind aggressive Cloudflare protection.
Download the content manually. Copy the content from your page and your competitors' pages into Google Docs, then link those docs in your sheet instead of the raw URLs. This is more reliable since there's no crawling to fail, but it adds a manual step each time you refresh the data.
For most cases, direct crawling is the better starting point. It's closer to the actual goal: a process that runs on its own.

Building the Workflow in n8n
Once your sheet is ready, build the n8n workflow as follows:
- Add a Firecrawl node to fetch your content and your competitors' content from the URLs in the sheet.
- Connect the AI model via its API and feed it your first prompt, instructing it to analyze both your content and the competitors' content against a quality framework, such as the elements Google's ranking systems weigh for topical depth and relevance. You define this framework yourself, since the criteria that matter will vary by industry and page type.
- Feed the output into your second prompt, which compares the results and generates concrete recommendations: what your competitors cover that you don't, what you cover that they don't, and what might be missing from both.
- Write the output back into the same Google Sheet you started with.
Format your competitor comparisons as short lists inside the sheet rather than dense paragraphs. This makes the recommendations easier to scan and easier to hand off to a writer.
How to Automate It on a Schedule
Set the n8n workflow to run on a recurring schedule so the audit happens without you triggering it manually. A monthly or quarterly cadence works for most blog and landing pages, though how often you refresh should match how competitive your market is and how frequently your competitors update their own content.
Each run produces the same result: fresh competitor data and updated recommendations written directly into your sheet, ready to hand to a copywriter or feed into an AI drafting step.
Where to Draw the Line on Automation
You can extend this workflow further, up to and including having AI draft and publish updated content automatically. Whether you should is a separate question. You're responsible for what reaches your users, not just what satisfies a ranking algorithm, so it's worth keeping a human review step before anything goes live.
Why This Setup Is Worth It for Content Marketing
The real value here is scale. The same sheet and workflow can hold dozens of keywords and URLs, so your entire content library gets checked against competitors on a rolling basis, not just the one page you set up first.
The setup itself is a one-time investment. After that, the main maintenance is adjusting your analysis criteria as your market shifts, not rebuilding the workflow.
