Repository metrics are context, not quality scores. Active installations measure adoption and can strongly reflect a plugin’s age and historical popularity. Ratings, recent updates and “Tested up to” metadata also do not guarantee modern code, error-free operation, security, feature completeness or suitability for a particular site.

Overview

About this plugin

Mester SEO is a powerful tool that connects your WordPress website to the central Mester SEO engine. It provides real-time SEO analysis, readability checks, and performance optimizations directly within your WordPress dashboard.

Major features include:

* Real-time SEO analysis in Gutenberg and Elementor.

* Readability score checking.

* AI-assisted SEO titles, meta descriptions, paragraph splitting, and passive-sentence review.

* Support for public custom post types and classic editors.

* Integration with WooCommerce and Gravity Forms.

External services

ir. The service validates API keys and performs requested central SEO, content, performance, and AI analyses. Features that depend on the central service require a valid API key; local SEO and readability features can operate without it.

When an administrator tests the connection, the API key and public site URL are sent to the service. When an authorized editor explicitly clicks an AI action, the focus keyword, current SEO title, and relevant editor content are sent for processing. The API key remains on the WordPress server and is not exposed to browser JavaScript.

After connection, authenticated central analysis requests may retrieve public content URLs, titles, post types, rendered published content, SEO titles and descriptions, focus keywords, pagination totals, and WordPress diagnostic information. These endpoints reject requests without the correct site API key.

The service is provided by Mester Gravity:
