Are there any official premium features or paid add-ons offered directly by Google for Blogger users?

Google does not offer any official premium features or paid add-ons directly for Blogger's hosting or platform itself. The core Blogger service, including all its built-in features, templates, and hosting, remains entirely free. Any 'premium' features or functionalities usually come from third-party developers who create custom templates, widgets, or tools compatible with Blogger, which you would purchase from those individual providers, not from Google.
