Zynith SEO

Zynith SEO is a lightweight plugin for WordPress that helps site owners manage search engine optimization without slowing down their websites. It is designed for users who want a single tool to handle meta tags, structured data, sitemaps, redirects, and custom scripts.

• On-Page Optimization: Edit meta titles, meta descriptions, and Open Graph images directly from the page editor. The Google SERP preview updates automatically as you type.
• Schema Markup Builder: Create structured data manually or use AI-generated schema templates. Supports multiple schema types including Article, Event, Product, and more.
• Automatic XML Sitemaps: The plugin regenerates sitemaps automatically and supports sites with over 25,000 pages by creating a sitemap index. You can also customize the sitemap filename.
• Custom Script Manager: Inject HTML, CSS, or JavaScript into specific pages or site-wide. Useful for adding tracking codes, analytics, or chat widgets.
• SEO Signals: Get real-time feedback on content length, HTML-to-text ratio, broken links, and internal/external link counts. Broken links appear as warnings in the page editor.

The plugin also includes a collapsible table of contents with custom CSS support, breadcrumbs for improved navigation, and a 404 monitor to track and manage broken URLs. It requires at least WordPress 5.0 and has been tested up to version 6.5.3.
