How to Filter AI Slop From Search Results: Tools and Steps

Low-quality, mass-produced pages and images, often called AI slop, can crowd search results. No setting removes all of it, but a few tools reduce it and two of them let you report what you find. This guide lists what Google, DuckDuckGo, Kagi and the uBlacklist extension offer, with the steps each source gives.

What counts as slop for a search engine

Google does not penalise content simply because AI wrote it. Its spam policies define “scaled content abuse” as generating many pages mainly to manipulate rankings rather than help people. Examples include using generative AI tools to produce many pages without adding value, scraping or stitching together content from other pages, and creating many pages that make little sense to a reader but contain search keywords. Knowing this definition helps you judge a result: thin, repetitive pages built to catch keywords are the target, whoever or whatever wrote them.

Report spam to Google

Google’s spam report page gives these steps:

1. Find the result you think appears because of spam.
2. Leave out any personal information, since Google may not process reports that contain it.
3. Open the report spam form at search.google.com/search-console/report-spam.
4. Fill it in and submit. Google says it may use reports to take manual action against a site.

Block sites with uBlacklist

The uBlacklist project page says the extension hides sites you choose from search results. It supports Google, Bing, Brave, DuckDuckGo, Ecosia, Kagi, SearXNG and Startpage for web, image, video and news results, and is available for Chrome, Firefox, Edge and Safari.

• Add a rule yourself. You can add rules from search result pages or from the toolbar icon. A match pattern such as *://*.example.com/* blocks a whole domain.
• Subscribe to a shared list. The project says you can subscribe to public rulesets, some of which are listed at ublacklist.github.io/rulesets.
• Sync. Rulesets can sync across devices through cloud storage or browser sync.

Blocking is manual and only hides domains you already know about, so it works best for sites that keep returning to your results.

DuckDuckGo: hide AI images

As Engadget reported on July 18, 2025, DuckDuckGo added a filter for AI-generated images. According to TechCrunch, you can open the Images tab and use the “AI images” drop-down to choose show or hide, or turn on “Hide AI-Generated Images” in search settings. It uses open-source blocklists, including the “nuclear” list from uBlock Origin and the uBlacklist Huge AI Blocklist. DuckDuckGo says it “won’t catch 100% of AI-generated results.” This filter covers images, not text pages.

Kagi: SlopStop and the AI images filter

Kagi’s help pages describe two features for its search engine.

• SlopStop. You click the shield icon beside a result and choose Report. If a result was flagged wrongly, choose “Report as not AI slop.” Kagi says reviews usually finish within a week, and you can track reports under Settings, Search, AI, SlopStop Reports. Flagged results are downranked rather than removed. A domain is flagged when most of its pages (roughly over 80%) are AI-generated, and a page on a mixed domain is labelled AI-generated but not downranked. See Kagi’s SlopStop page.
• AI images filter. In Kagi image search, set the AI images filter to None, or add ai:none to the query. Kagi notes detection relies on a site’s reputation rather than each image, so some AI content may still appear. See Kagi’s exclusion page.

A simple routine

1. If you use Google or another engine without a native filter, install uBlacklist and subscribe to a public ruleset.
2. Add any site that repeatedly returns thin, keyword-stuffed pages to your own rules.
3. For image searches on DuckDuckGo or Kagi, turn on the AI image filter.
4. Report clear spam through Google’s form or Kagi’s SlopStop so the engines can act on it.

Limits

All of these tools are imperfect. DuckDuckGo says its filter will miss some images, Kagi says detection can miss content on mixed sites, and uBlacklist only hides what you tell it to. A filter is not a verdict on accuracy: for health, money or safety questions, check a primary source regardless of how a page looks.
