SEO for developers

Wire SEO checks into the same workflows you use for tests and deploys. GitHub Actions, n8n, AI agents, WordPress plugins — every integration pattern with worked examples.

SEO regressions don't show up in your test suite. They show up six weeks later in Search Console, after a deploy renamed an H1 or dropped a meta tag. The fix is the same as it was for unit tests: run the check on every PR, fail the build if it regresses, surface the diff. This hub collects every integration pattern we have published — pick the one that fits your stack.

Frequently asked

Can I run SEO Score API in CI/CD?

Yes. We publish an official GitHub Action that fails the build when an SEO score drops below a threshold. For GitLab, CircleCI, or any other CI, call the REST API directly with curl or our SDKs in Python or Node.

Is there a Python or Node SDK?

Yes — `seoscoreapi` on PyPI and `seoscoreapi` on npm. Both at v1.1.0. There is also an n8n community node for low-code workflows.

How do I use SEO Score API from an AI agent?

Treat it as a tool/function call. Give the agent the URL, it calls /audit, you get back JSON it can act on. There is a Claude Code skill that wires this up directly in the terminal — see the post above.

How is this different from Lighthouse?

Lighthouse is a CLI/library focused on performance and Web Vitals. SEO Score API is a hosted API focused on broader SEO depth — 80+ checks including on-page, schema, AI readability, SXO/AEO/AIO. Different scope, different shape. Many devs run both.
