P4J - SEO Check helps you understand the real SEO structure of your Joomla!® website, one page at a time. Instead of relying on generic scores, it provides clear, practical checks that show what works, what needs attention and where improvements can be made.

Key Features

Complete on-page SEO inspection
Check page titles, meta descriptions, H1 headings, heading hierarchy, canonical URLs, indexing directives, image alternative text, internal and external links, mobile viewport settings, Open Graph tags and structured data.

Analyse real Joomla!® pages
Select any published menu item or article, or enter a URL from your website. SEO Check examines the HTML delivered to anonymous visitors, including elements added by Joomla!®, the template and page builders.

Clear, actionable results
Checks are organised into errors, items to review, successful checks and informational messages. Problems appear first, making it easy to identify what deserves attention without chasing an arbitrary SEO score.

Visual heading structure
Explore the complete H1–H6 heading hierarchy in the order it appears on the page. Identify missing or duplicated H1 headings, skipped heading levels and headings generated outside the main content by templates or modules.

Target keyword analysis
Enter an optional target keyword or phrase and check its presence across seven important positions: page title, H1, URL, meta description, first 100 words, subheadings and image alt text. Review its frequency, density and relevance to the actual content.

Discover dominant words and phrases
Find the twelve most significant words and the recurring two- or three-word phrases in your content. Understand which topics your page actually emphasises and whether they match your intended SEO targets.

Indexing and technical checks
Detect noindex and nofollow directives, missing or conflicting canonical URLs, HTTP response issues, missing language attributes, mobile viewport problems, incomplete social sharing metadata and invalid JSON-LD structured data.

Private, read-only analysis
All analysis runs directly in your browser. The component does not modify Joomla!® articles, metadata or configuration settings, creates no database tables and does not save analysis results. No external SEO service or API subscription is required.

Simple administration
Access SEO Check from the Joomla!® Components menu. No configuration is needed after installation. The component is restricted to Super Users and includes English and Italian interface translations.

Focus on what matters
P4J - SEO Check does not promise higher rankings or reduce SEO quality to a single number. It gives you the information needed to make informed improvements to your website, with a lightweight, straightforward workflow.
