Make sure to update WordPress, WooCommerce, plugins, extensions, and the theme frequently. If a theme or plugin is no longer supported by its developers, then it’s time to consider ditching them.
Likewise, if a theme/plugin adds unnecessary bloat to your dashboard, start looking for better alternatives. For instance, you might want to consider alternatives to plugins that serve aggressive ads in your dashboard.
This issue is so prevalent that there are plugins solely dedicated to removing bloat from some of the most popular WordPress plugins.
