What uBlacklist does well

  • One-click block from results. When a junk site appears in your results, a “Block this site” link appears next to it. One click and you’ll never see that domain again.
  • Community blocklists. Subscribe to maintained lists for content farms, AI-spam sites, Pinterest mirrors, recipe-blog wrappers. The uBlacklist Huge AI Blocklist is the de facto standard.
  • Regex and wildcards. Block patterns like *.medium.com/* or /(quora|chegg)\.com/.
  • Cross-browser, cross-engine. Works on basically every major search engine you’d actually use.

What uBlacklist doesn’t do

  • Filter social feeds. It only acts on search results. For Reddit, use Ultimate Reddit Filter. For social, use News Feed Eradicator.
  • Block direct visits. If you type the URL or click a non-search link, uBlacklist doesn’t fire.
  • Auto-sync. You wire up Google Drive or Dropbox yourself the first time.

Best for

Anyone whose search results in 2026 are choked with AI-generated content, content farms, or specific sites they’ve sworn off (Quora, Pinterest, Medium clones).

Setup in 2 minutes

  1. Install uBlacklist from iorate.github.io/ublacklist for your browser.
  2. Open the options page.
  3. Subscribe to a community list — the AI content-farm blocklist is a good starting point.
  4. Search Google. When junk appears, click Block this site beside it.
  5. (Optional) wire up Google Drive sync.

Alternatives

  • Kagi search — paid search engine with native domain blocking and ranking adjustments built in. Different model entirely.
  • Manual -site: Google operators — works but doesn’t persist between searches.

Frequently asked questions

Partially. It removes blocked domains from organic results and from sources cited in AI Overviews where the citation surfaces as a normal link. The generated summary text itself is not filtered.
