Slim SEO is an upcoming SEO plugin for WordPress that is designed to be as lightweight and easy to use as possible.
The plugin is being designed with a UI-first approach and with a heavy emphasis on being extendable. This means that instead of cramming every possible useful feature in at release (and adding a lot of bloat), there will be one lightweight base plugin with just the right amount of features, and optional add-on plugins tailored to more specific needs.
Slim SEO is still very much a work in progress – feel free to reach out if you have any feedback or want to help develop or test the plugin when it is ready.
