## Description

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

This plugin connects to the Mester SEO service hosted at mestergravity.ir through
the regional API relay at relay.mestergravity.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:
