What is AI slop
AI slop is low-quality content that someone makes in bulk with generative AI and publishes with little or no human editing.
Merriam-Webster chose "slop" as its 2025 Word of the Year and defines it as "digital content of low quality that is produced usually in quantity by means of artificial intelligence." AI slop reads smoothly and tells you nothing new.
AI slop defined for marketers
For marketers, AI slop is any page or post that a model drafted and nobody improved before it went live. The problem is the lack of editorial intervention. Slop comes from a publishing quota that nobody on the team has time to check, so pages ship with no facts or judgment added. The pages also lack experience. To test a draft, ask whether you'd still publish it if search engines didn't exist.
Why AI slop hurts visibility
AI slop hurts visibility because search engines and AI assistants find nothing in it that they can't get elsewhere. A generic paragraph matches thousands of others, so Google ranks the page that first said it well, and assistants cite the source with the specific figure. Readers also leave quickly when they get nothing they can use. Low-value pages can drag down how a search engine judges the rest of your domain, too.
How AI detects low-quality content
Search engines use AI to compare each page with what they've already indexed and to look for signs of effort. Google says its spam-fighting work goes on "however spam is produced" and describes that work as including its SpamBrain system. Warning signs include near-duplicate programmatic pages and a site's page count that grows fast while quality stays flat. Don't rely on the "AI detector" tools that guess whether a model wrote a text. Search engines judge quality, and authorship isn't the test.
What AI slop looks like
You can tell content reads like AI slop when its claims would fit on a competitor's page without changing a word. The signs show up in two places.
Signs in the writing
Signs in the substance
Slop gives numbers without sources, or numbers that don't exist anywhere. It has no example from real work and no named person. It answers the question loosely and then repeats itself to fill space. If you delete half the sentences and the page loses nothing, it's slop.
Avoid producing AI slop
To avoid publishing AI slop, put someone who knows the subject between the model and the publish button.
- 011Write a brief that names the reader and the question they came with.
- 022Give the model your own material, such as data or notes. Interview quotes are another option.
- 033Check every fact against a source, and delete what you can't verify.
- 044Cut each sentence that adds no fact or reason and gives the reader no step to take.
- 055Read the page as the reader would before it goes live.
AI slop vs original content
Original content holds something only its author could supply, while slop repeats the average of what's already online. The content generator doesn't decide which one you get. Danny Sullivan and Chris Nelson of Google's Search Quality team wrote that "appropriate use of AI or automation is not against our guidelines." So an AI-assisted content page built on a practitioner's numbers counts as original. A hand-typed rewrite of the top 10 results is still slop.
How search engines penalise slop
Search engines penalise AI slop through automatic demotion and manual action. Google's scaled content abuse policy, added on March 5, 2024, targets "many pages" created mainly to manipulate rankings. Core updates and SpamBrain push those pages down without any notice to you. In a manual action, a human reviewer flags the site, and the Manual Actions report in Search Console shows it. Pages stay demoted or removed until you fix them and file a reconsideration request.
