Users appreciate the plugin for its simplicity and minimal bloat compared to other SEO plugins. They like how it utilizes built-in post excerpts instead of custom meta, providing needed functionality like displaying manual excerpts in descriptions for social media and search engines. The plugin is praised for being exceptionally lightweight (8KB zipped) and having a responsive developer. However, some issues include it setting the same description for all pages, negatively impacting SEO, and non-functioning Excerpt or Open Graph options. Suggestions for improvement include adding a button for selecting images directly from the library for Open Graph images.
