I Built an SEO Agent That Replaces Manual SEO Work (n8n)
Most businesses waste $300/month on SEO tools when they could automate competitor analysis instead. This n8n workflow pulls domain rankings, top pages, keyword performance and competitor visibility - delivering Ahrefs-level insights at a fraction of the cost.
The Problem With Expensive SEO Tools
SEO professionals know they need competitor data to succeed, but most rely on expensive tools like Ahrefs and SEMrush that cost $300/month or more. These platforms provide valuable insights, but their subscription models create recurring costs that add up quickly - especially for agencies managing multiple clients.
The breakthrough came when we discovered SEO APIs that offer pay-per-use access to similar data. By combining these APIs with n8n's automation capabilities, we built a workflow that delivers comparable insights at a fraction of the cost. Instead of paying monthly subscriptions, you only pay for the data you actually use.
Cost savings: This workflow reduces SEO tool expenses by 80-90% compared to traditional subscriptions. Where Ahrefs might cost $300/month, this solution averages $30-50/month for most users.
How The SEO Agent Works
The workflow consists of four connected processes that analyze different aspects of competitor SEO performance. Unlike manual tools that require separate reports, this system consolidates all data into a single Google Sheet for easy analysis.
At 2:15 in the video, you can see how the workflow begins with a simple API call to the SEO data provider. The four main components are:
- Domain Rank Overview: Shows estimated organic traffic and domain authority metrics
- Relevant Pages: Identifies the website's top-performing content
- Ranked Keywords Performance: Extracts search volumes and keyword difficulty
- Competitor Visibility Overview: Reveals competing domains ranking for similar terms
Each process runs sequentially, with the results automatically populating separate tabs in a Google Sheet. This creates a comprehensive competitor analysis dashboard without manual data entry.
Domain Rankings Analysis
The first module provides a high-level view of a domain's SEO performance. It answers fundamental questions like: How much organic traffic does this site get? What's their domain authority? How does their search visibility trend over time?
At 3:45 in the video, we analyze safehome.org - a home security site getting 1.5 million monthly organic searches. The workflow reveals this key insight immediately, whereas manual tools would require navigating multiple reports.
Key metric: Organic ETV (Estimated Traffic Value) shows how much a site's organic traffic would cost if purchased as ads. For safehome.org, this exceeds $500,000/month - proving the value of their SEO strategy.
Identifying Competitor's Best Pages
The second module extracts a website's top 100 performing pages - the content driving their organic traffic. This is gold for SEO strategists, as it reveals exactly what content works best in your niche.
At 5:20 in the video, we see how safehome.org's "/security-systems/best" page ranks #1 for 486 different searches. This immediately identifies their money page - the content generating the most conversions.
Three ways to use this data:
- Analyze page structure (headings, internal linking) of top performers
- Identify content gaps where you could create better versions
- Discover lucrative sub-niches you may have overlooked
Keyword Performance Data
The third module extracts all keywords a domain ranks for, along with search volumes and difficulty scores. This reveals their keyword strategy - which terms they prioritize and how they perform.
At 8:10 in the video, we see safehome.org focuses on transactional keywords like "alarm security systems" rather than informational content. This makes sense for their business model, as these terms convert better.
Pro tip: Sort keywords by "number one positions" to identify a competitor's most valuable terms - these represent their highest-converting traffic sources.
Competitor Visibility Overview
The final module is perhaps the most powerful - it identifies competing domains you may not have known about. By analyzing who ranks for similar keywords, you discover secondary competitors and new opportunities.
At 10:30 in the video, we see how safehome.org competes with major publishers like New York Times and US News in the home security niche. This reveals the competitive landscape beyond direct competitors.
Practical applications:
- Find lower-authority sites outperforming on specific terms
- Discover content partnerships or acquisition targets
- Identify underserved niches with less competition
Implementation Tips
To get the most from this workflow, we recommend running it monthly for your top competitors. Track changes in their rankings and new pages to stay ahead of their strategy.
Three best practices:
- Focus on money pages: Prioritize analyzing pages ranking for commercial keywords
- Track trends: Compare monthly reports to spot emerging opportunities
- Expand gradually: Start with 3-5 competitors, then add more as needed
The workflow's cost-effectiveness allows this frequent analysis - something prohibitively expensive with traditional SEO tools.

In summary: 1) Automating SEO analysis saves hundreds monthly, 2) Focus on competitor's money pages and commercial keywords, 3) Regular tracking reveals emerging opportunities before competitors capitalize on them.

The workflow has four key components that analyze different aspects of competitor SEO performance. Each process feeds data into a consolidated Google Sheet for easy analysis.
These components work together to provide a comprehensive view of how competitors rank, what content performs best, which keywords drive traffic, and who else competes in the space.
- Domain rank overview (traffic estimates)
- Relevant pages (top-performing content)
- Ranked keywords (search volumes)
- Competitor visibility (alternative domains)
Analyzing competitor's top-ranking pages reveals their most profitable content strategies. These pages represent what actually works in your niche - the content that converts visitors.
By reverse-engineering these pages, you can identify patterns in their structure, internal linking, and keyword targeting that you can adapt for your own content.
- Discover high-converting page structures
- Identify content gaps in your strategy

The workflow extracts comprehensive keyword data including search volumes, ranking positions, and difficulty scores. It also categorizes keywords as transactional or informational.
This helps prioritize high-value commercial keywords that drive conversions. You can see exactly which terms bring competitors the most valuable traffic.
- Search volumes (potential traffic)
- Keyword difficulty (competition level)
- Commercial intent (transactional vs informational)
This feature automatically identifies competing domains ranking for similar keywords. It reveals secondary competitors you may not have known about, expanding your competitive analysis.
The system analyzes search results to find domains appearing for the same keywords as your target competitor. This shows the full competitive landscape beyond obvious players.
- Discovers indirect competitors
- Reveals niche players outperforming on specific terms
