Introduction
Kirby SEO Audit is a plugin for Kirby CMS that brings the Yoast SEO v3 analysis engine – the one millions of WordPress users rely on – into the Panel. Everything runs in the editor's browser; no external services, no API calls, no data leaving the host.

How It Works
There are two ways to run SEO audits in your Kirby Panel:
- View Button Recommended: Add a single line to your blueprint and get an SEO Audit button in your page header. Click it, and the analysis results appear in a dialog.
- Section: Add a section to your blueprints for inline audit results. Click the "Analyze" button in the section to run the analysis.
Both methods use the same analysis engine and support the same configuration properties.

Assessment Engine
Kirby SEO Audit analyzes your content using two categories of assessments:
- SEO Assessments: Assessments covering keyword optimization, meta data, links, and technical SEO
- Readability Assessments: Assessments focusing on content structure, sentence length, and readability
All assessments run locally in your browser using the Yoast SEO v3 engine – no external web services or API calls are made. Results are organized into Good, OK, Bad, and Feedback categories regardless of their SEO or readability classification.
