What it is
The Google SERP Tracking API allows you to access your ranking data via API instead of the web interface.
You can:
Retrieve keyword rankings
Access historical ranking data
Pull movement metrics
Access keyword metrics (search volume, intent, CPC, etc.)
Retrieve Share of Voice data
Trigger keyword updates
This enables automation, dashboard integrations, internal tooling, and large-scale reporting.
Why it matters
The API is ideal if you:
Build custom dashboards
Manage large keyword sets
Operate at agency or enterprise scale
Integrate SEO data into BI systems
Automate reporting pipelines
Feed ranking data into client portals
Instead of manually exporting CSVs, the API allows you to build a fully automated SERP reporting stack.
