Frequently Asked Questions

What is a domain lookup?

A domain lookup provides comprehensive SEO intelligence about any website, including contact information, social media profiles, backlinks, and domain authority metrics. SeoMCP analyzes data from our crawl of over 46 million domains to provide accurate, up-to-date insights.

What data can I see for free?

Our free domain lookup shows detected email addresses, phone numbers, social media profiles, backlinks, and domain ranking metrics. For programmatic access to this data, you can use our REST API or connect via the Model Context Protocol (MCP).

How often is the data updated?

Our web crawler processes data on a regular crawl cycle. Each crawl covers millions of domains and billions of backlinks. The crawl date is displayed on each domain profile page.

What is MCP and how does it work?

The Model Context Protocol (MCP) allows AI agents like Claude, Cursor, and other LLM-powered tools to directly query our SEO database. Instead of scraping web pages, AI agents can call structured tools to get backlinks, domain authority, and contact information programmatically.
