How does keyword research work?

We fetch real-time suggestions from Google, YouTube, Bing, and Reddit, then analyze them to categorize intent (Informational/Commercial/Transactional) and estimate difficulty based on keyword structure and competition signals.

How does the free trial work?

Pro includes a 1-day free trial. Cancel anytime during the trial and you will not be charged. After the trial, you will be billed $12/month automatically.

Can I use this without Claude Code?

Yes! The REST API works with any HTTP client - curl, Postman, Python, JavaScript, etc. The MCP server is optional for Claude Code users.

What data sources do you use?

Google, YouTube, and Bing autocomplete suggestions combined with Reddit discussion data. Multiple sources give you more keyword ideas than any single provider.

How accurate is intent categorization?

Our algorithm analyzes keyword patterns, modifier words, and structure. Accuracy is approximately 85% based on manual testing. Always review results for critical content planning.

Can I export results?

Yes, use the export functionality in the dashboard to download CSV with all keyword data (keyword, intent, difficulty, source, volume).

Is there an MCP server?

Yes! Install with npm install -g @delulu9/seo-mcp-server. It enables keyword research directly from Claude Code conversations.

Do you store my API requests?

We store session results temporarily (for CSV export) but don't permanently log your queries. Your data is your data.

Can I upgrade or downgrade anytime?

Yes, upgrade to Pro instantly. Downgrade anytime - you'll keep Pro access until the end of your billing period.
