On-page SEO analysis with content scoring and recommendations.

A WordPress plugin that performs on-page SEO analysis on every post and page. Displays an SEO score (0-100) and a list of checks with pass/warn/fail status in a meta box on the post edit screen. Checks include title length, meta description, heading structure, image alt attributes, internal links, content length, and readability.

The plugin adds a SEO description field to the post editor for setting a custom meta description. Auto-analysis runs on post publish. The meta box shows a visual score badge (green, yellow, or red) and a detailed check table with icons and explanations.

Each check can be toggled on/off in the settings. The minimum content length is configurable. The readability check measures average sentence length and flags content with overly long sentences.
