SEO Documentation: Audit Rules, API, CLI and MCP

Every check a QuikSEO audit runs, grouped by topic, with its severity, the exact condition, the exceptions and the sources behind it. The guides cover the API, the CLI and GitHub Action, the site contract and the MCP server. Rule set 2026.10.7.

01 — Rules

SEO Audit Rules With Sources

Each rule checks one thing, cites the documentation it relies on and returns one of five states. Open a rule for its condition, its exceptions and how to fix it.

pass · fail · review · not_applicable · not_checked

Rule States and Severity

The score is the share of applicable checks that passed, so a failed check, a result to review and a check that could not run all lower it. Severity orders the fixes, and a rule that could not run is never reported as passed.

How the audit score is calculated

Rules as a Technical SEO Checklist

Read the groups below in order and you have a checklist for a page: indexing first, then HTTP, canonical, head and content. Every item links to the page that explains exactly when it passes.

02 — Integrations

Integrations for Developers

The same rules run from your code: one API key works for the REST API, the command line tool and its GitHub Action, and the MCP server.

api:rest

API

Start audits, list findings and read reports over HTTPS.

npx quikseo

CLI and GitHub Action

Check the HTML of a build and fail the job on new findings.

mcp:http

MCP Server

Let an AI coding agent audit, fix and re-audit a page.

03 — Site contract

Site Contract for Your SEO Guidelines

Write your own conventions, such as the URL policy, the title pattern or Title Case headings, as assertions in quikseo.config.json. Every audit checks them next to the rules, and they never change the score.

Read the site contract guide
quikseo.config.json
{
  "version": 1,
  "assertions": [
    { "id": "heading-case", "type": "headingCase",
      "style": "title", "levels": [1, 2, 3], "severity": "warning" }
  ]
}
