1. Using the WordPress Plugin Boilerplate as a starting point for your plugin. This ensures that your plugin is structured properly and follows WordPress coding standards.
  2. Using proper WordPress functions and APIs to interact with the WordPress database, rather than writing your own custom SQL queries.
  3. Using the wp_enqueue_script() and wp_enqueue_style() functions to properly enqueue your JavaScript and CSS files, respectively.
  4. Using the register_activation_hook() and register_deactivation_hook() functions to properly handle plugin activation and deactivation events.
  5. Using the add_action() and add_filter() functions to properly attach your custom functionality to WordPress core actions and filters.
  6. Using a version control system, such as Git, to manage and track changes to your plugin code.
  7. Properly documenting your plugin code using inline comments and PHPDoc blocks.
  8. Testing your plugin thoroughly before releasing it to the public. This includes testing for compatibility with different versions of WordPress, different browsers, and different server environments.
  9. Maintaining a changelog for your plugin to keep track of changes and updates.
  10. Being responsive to user feedback and bug reports, and releasing regular updates to improve your plugin.
