How to Do SEO with Claude Code (2026 Guide)

Can You Do SEO with Claude Code?

Yes. Claude Code becomes a powerful SEO tool when you connect it to data through MCP servers. Instead of switching between browser-based SEO tools and your editor, you run keyword research, content analysis, and technical audits directly in Claude Code.

The key is giving Claude Code access to real SEO data. Without an MCP server, the AI can only work with what you paste into the conversation. With an MCP server like Delulu9, Claude Code can query live keyword data from Google, Bing, and Reddit on demand.

Setting Up Claude Code for SEO

Step 1: Install Delulu9 MCP Server

Add the Delulu9 MCP server to your Claude Code configuration:

{
  "mcpServers": {
    "delulu9": {
      "command": "npx",
      "args": ["-y", "@delulu9/seo-mcp-server@latest"],
      "env": {
        "DELULU9_API_KEY": "your-api-key"
      }
    }
  }
}

This gives Claude Code access to keyword research, Entity Panel analysis, and Edge Cache scoring.

Step 2: Verify the Connection

Restart Claude Code and test:

"Can you check Delulu9 connection? Search for 'keyword research tools' and show the results."

If it returns keyword data with search volumes and intent classifications, you’re set.

SEO Workflows in Claude Code

Keyword Research Workflow

Ask Claude Code:

1. “Find 50 keyword ideas for [your niche] using Delulu9”
2. “Filter these by commercial intent and low difficulty”
3. “Group the winners into topic clusters”
4. “Create a content brief for the top cluster”

This replaces hours of manual work with a 5-minute conversation.

Keyword Clustering Workflow

Claude Code can handle keyword clustering when connected to the right data:

• Pull relevant metrics through MCP
• Analyze patterns the AI identifies
• Generate actionable recommendations
• Prioritize by impact and effort

Search Intent Analysis Workflow

For search intent analysis, use Claude Code to:

• Fetch current data from connected tools
• Compare against competitors
• Identify gaps and opportunities
• Create an implementation plan

Content Optimization Workflow

Ask Claude Code to:

1. Research target keywords for a page
2. Analyze search intent behind each keyword
3. Check what’s currently ranking (using web search)
4. Generate optimization recommendations
5. Write or improve the content directly

What Claude Code Can and Cannot Do for SEO

The pattern is clear: Claude Code is excellent at analysis and content creation, but needs data access through MCP to do real SEO work.

Claude Code vs Browser-Based SEO Tools

Tips for Better SEO Results in Claude Code

1. Be specific with prompts. Instead of “find keywords,” say “find long-tail keywords for [industry] with commercial intent and difficulty under 30”
2. Chain queries. Build on previous results within the same conversation
3. Ask for sources. When Claude Code makes claims about SEO, ask it to verify with live data from Delulu9
4. Save workflows. When you find a prompt sequence that works well, save it for reuse
5. Combine tools. Use multiple MCP servers for a complete SEO toolkit
