How to Permanently Exclude a Website from Search Engine

Google abandoned its own "Personal Blocklist" feature years ago, leaving users defenseless against recurring junk sites. To permanently exclude a website from a search engine today, you have to run a local script. The Search Cleaner extension restores this lost functionality beautifully. By caching your excluded domains in browser storage, the extension intercepts your search result data and filters the specific website out of the feed before the page even fully paints to your screen.
