Semrush provides a public API for developers needing direct, programmatic access to its keyword, backlink, traffic, and competitive intelligence data. An MCP (Model Context Protocol) integration allows AI assistants to query Semrush data natively within AI-driven workflows. Additional integration points include Google Analytics, Google Search Console, Google Ads, Meta Ads, ChatGPT, Adobe, and Lovable. API access and integration depth may vary by plan tier; enterprise plans support custom configurations. Add-ons, including additional user seats (from $45/mo), can be layered onto any paid subscription.
