Slim SEO

Slim SEO is a lightweight WordPress plugin that handles search optimization automatically, so beginners can install it and get on with running their business. It generates meta tags, schema markup, XML sitemaps, breadcrumbs and image alt text without much configuration, and it manages redirects while monitoring missing-page errors to catch broken links. A Pro version adds advanced schema, link management and a Writing Assistant that gives real-time feedback while you write. A free version is available on wordpress.org. Slim SEO also works with the WordPress Abilities API and an MCP Adapter plugin, which lets AI apps such as Claude or Cursor connect to a WordPress site and carry out editing tasks. It integrates deeply with Meta Box and ACF for custom field data.
