A real-time, lightweight on-page SEO checklist for the WordPress editor, focusing on core ranking signals and E-E-A-T.

Description

The Ultimate SEO Checklist provides instant, real-time feedback on your post's SEO performance directly within the Classic Editor (or Gutenberg Code Editor). Unlike heavy, resource-intensive SEO plugins, this lightweight tool focuses solely on critical, high-impact on-page factors like Core Web Vitals (via proxy checks) and E-E-A-T signals.

It calculates a weighted score out of 100 based on three categories: Core Optimization, Strategic/Advanced SEO, and Technical/UX checks.

Key Features Include:

• Real-time Scoring: Get an instant weighted score without needing to save or update the post.
• Targeted Checks: Focuses on essential checks: Keyword in H1, Title, URL, and density.
• Featured Snippet Optimization: Specific checks for the "Quick Answer Format" (Question Hx followed by a concise P tag).
• CWV Proxy Checks: Includes checks for Image Dimensions to prevent Cumulative Layout Shift (CLS).
• E-E-A-T Signals: Checks for Author and Post Date metadata presence to satisfy Google's quality guidelines.
• Anchor Risk Warning: Alerts you if you use the Focus Keyword as anchor text, a common SEO mistake.

Installation

1. Upload the ultimate-seo-checklist folder to the /wp-content/plugins/ directory.
2. Activate the plugin through the 'Plugins' menu in WordPress.
3. Navigate to any Post or Page editor.
4. Enter your Focus Keyword in the sidebar box to begin the real-time audit.

Frequently Asked Questions

Does this plugin work with the Classic Editor?

Yes, this plugin is designed to work seamlessly within the Classic Editor interface. It also works when the Gutenberg editor is switched to Code mode.

Does this plugin store data in the database?

How is the score weighted?

The score is calculated based on three weighted categories:

• Core Optimization: 50%
• Strategic/Advanced SEO: 30%
• Technical/UX Checks: 20%
