GA4
Google's next-generation analytics platform for websites and applications, replacing Universal Analytics. It adopts an event-based tracking model and supports custom channel groups and BigQuery data export.
Timeline (last 90 days)
GA4's custom channel groups take effect retroactively in reports, and once created you can immediately see historical data.
There are exactly three signals by which AI referral traffic arrives at a site: the Referrer request header, UTM parameters, or no signal at all (falling into Direct).
The GA4 interface is sufficient when viewing trends, but analyzing landing pages, doing data joins, or writing custom logic requires using the BigQuery export.
The collected_traffic_source field in GA4 export data only exists after mid-2023, and earlier data can only be judged by referrer.
Clicks brought by Google's AI Overviews and AI Mode are usually classified in GA4 as ordinary Google organic search traffic and do not appear in AI referral statistics.
GA4's default channel groups are built-in and cannot be modified, while custom channel groups allow you to copy them, add or remove rules, and specify the scope of application.
GA4 channels match in order, and the first rule that matches determines session attribution with subsequent rules no longer evaluated, so the AI assistants channel must be dragged above Referral to separately identify AI referral traffic.
The modern SEO engineering stack includes data collection (Search Console API, GA4, crawlers, server logs), programming (Python, JavaScript, SQL), data processing (Pandas, DuckDB, PostgreSQL), AI (LLM APIs, embeddings, vector search), automation (GitHub Actions, scheduled tasks), testing (Pytest, Playwright, custom validators), monitoring (dashboards, alerts, anomaly detection), and deployment (Git, CI/CD, cloud infrastructure).
OpenSEO MCP Skills runs on the free SEO MCP server Rise Connector, with ranking data sourced from users' real Google Search Console and traffic data taken from users' GA4 properties.
