wanghaisheng/auto-submit-backlink ? reverse-engineered prompt

Build me a simple browser extension and website for daily backlink submission.

I want users to be able to add their site details once, then use the extension to help submit backlinks and get pages indexed on Google more easily. It should support posting to multiple sites, keep a list of supported sites, and make the daily workflow feel very easy, with a clean popup or dashboard where someone can manage their links and run the submission flow.

Please include the basic public pages too, like a homepage, privacy policy, and terms pages, so it feels like a real product. Keep the design simple and practical, and make it work smoothly in the browser. If you need current extension guidance or Google related details, look up the latest docs online first.
