What it does
Many SEO plugins grow large over time and add settings you may never touch. This plugin keeps its footprint small, at 87KB, while still covering the on-page work most sites need. You can write custom meta titles and descriptions so you control how pages are presented in search results, and Open Graph tags shape how your content looks when people share it on social networks.
Structured data is often the hardest part of SEO for site owners, so the plugin includes its own schema builder with AI-assisted generation to help you create markup without writing it by hand. Alongside that, you get tools for sitemap management, a robots.txt editor for controlling crawler access, and breadcrumbs support for clearer site navigation. It suits bloggers and businesses who want these tools in a compact plugin.
Best for
- Bloggers who want a compact on-page SEO plugin
- Small business websites managing their own SEO
- Site owners who need help creating schema markup
