The Search Engines Blocked Warning plugin is a useful tool for WordPress users, particularly when transitioning a site from development to production. This plugin alerts administrators with a warning in the WordPress dashboard when the 'Search Engine Visibility: Discourage search engines from indexing this site' option is enabled. This feature is crucial to prevent unintentional blocking of the site from search engine indexing, which can hinder visibility in search results.

With a simple installation, this plugin ensures that users are reminded of the importance of disabling the indexing option, especially after moving a site live. It requires PHP version 5.6 or greater and is available in both English and Spanish, making it accessible to a wider audience. The plugin is free to use and aims to enhance the management of search engine visibility effectively.
