Users appreciate the Simple SEO WordPress plugin for its simplicity, ease of use, and effectiveness in handling SEO tasks without unnecessary complexity. They find it lightweight and practical, giving them control over metadata without the bloat of more complicated plugins. The plugin is lauded for its quick setup, intuitive interface, and regular updates. However, some users have reported bugs, such as incorrect Open Graph URL tags and issues with saving theme settings. There's also concern about redirects to third-party sites during imports, which some find suspicious. Some suggest improvements like pagination support in titles and better customer support with more configuration guidance.
