  • Provides access to a comprehensive ecosystem of data—from SERP insights, such as keyword rankings and backlinks, to website traffic, including AI search traffic data from AI-powered search engines and assistants like ChatGPT, Gemini, and Copilot.
  • Delivers website audience insights, key traffic channels, and market trends, enabling you to evaluate your domain performance across industries.
  • Supports local listing management, helping you maintain consistent business information across locations and track your location ranking on Google Maps.

Jump to API versionsAPI versions

Two Semrush API versions are available: version 3 and version 4.

The main difference between versions is the authorization method, availability of major changes inside the feature APIs, and list of available feature reports.

Each version consists of product groups, products themselves, and product reports.
