How to Generate Anthropic SEO Keyword Research?

Turn your ideal customer profile into a ready to use list of seed keywords. Great for marketers who need quick keyword ideas for content, ads, and on page SEO. Run it on demand during planning sessions or when launching a new offer.

Here is how it works. You click run to start. The Set node holds your ideal customer profile details. The Aggregate node bundles that input for the AI. The Anthropic Chat Model powers an AI Agent that creates a list of about 20 seed keywords. The Split Out node breaks the AI answer into individual items so each keyword can be stored or reviewed. A placeholder node marks where you can send the list to your own database or sheet.

To use it, you need an Anthropic API key and a clear ideal customer profile. Expect a run cost of a few cents and a fast result that replaces long brainstorming. Use it to plan blog topics, name ad groups, and find early content clusters for a new site or product.

How do you set it up?

  1. Import the template into n8n: Create a new workflow in n8n > Click the three dots menu > Select 'Import from File' > Choose the downloaded JSON file.
  2. You'll need accounts with Anthropic. See the Tools Required section above for links to create accounts with these services.
  3. Create an Anthropic API key in your Anthropic account. Copy the key and store it in a secure place.
  4. Open the Anthropic Chat Model node in n8n. In the Credential to connect with dropdown, click Create new credential, select API Key, paste your key, name the credential clearly, and save.
  5. Open the Set Ideal Customer Profile node. Replace the placeholder fields with your product, audience, and problem details. Keep text concise and clear.
  6. Open the AI Agent node. Make sure the instructions ask for a list of 20 seed keywords and that the final answer is an array placed in output.answer.
  7. Check the Split Out node. Confirm the field to split is output.answer so each keyword becomes its own item.
  8. Replace the Connect to your own database node with your target app, such as Airtable, Google Sheets, or a SQL node. Double click the new node, create credentials, and map the keyword field to a column.
  9. Click Test workflow. Review the Split Out items. You should see about 20 records. If you see one long string, update the AI Agent prompt to return a clean JSON array.
  10. If you get API errors, verify the Anthropic credential, check key permissions, and try again. If costs are a concern, keep prompts short and limit output to 20 items.
  11. Once results look correct, publish or run the flow on demand from the n8n editor.
