What is AI slop? How to spot mass-produced AI websites

AI slop is low-effort content mass-produced with generative AI and published with little or no human review. The term spread in 2024 to describe the flood of filler articles, fake product roundups, generic recipe pages and odd AI images that started crowding search results and social feeds. On the web, slop usually exists for one reason: to catch search traffic and turn it into ad views or affiliate clicks.

This guide explains how slop differs from an ordinary AI-built site, the signs that give it away, and what you can do about it.

Slop is not the same as "built with AI"

It is easy to lump these together. They are separate questions:

• Built with AI is about the tool. A florist who builds their site with Lovable has an AI-built site. It may be useful, honest and carefully written.
• Slop is about effort and intent. A content farm publishing two hundred "best air fryer" pages a day is slop, whether it uses a chatbot, cheap freelancers or both.

Kitsuvo keeps them apart for this reason. The AI-built score is a neutral note about how a site was made. Slop has its own label, with its own evidence. You can read more about the first in what is a vibe coded website?

The signs of AI slop on a web page

Ordered from strongest to weakest:

1. Chatbot replies pasted into the page. Phrases that only make sense in a chat window: As an AI language model, Certainly! Here's, I hope this helps!, As of my last knowledge update, or even Regenerate response. Nobody who read the page before publishing would leave these in.
2. Template slots nobody filled in. Square-bracket placeholders like [Insert product name], [Your Name], [City] or [keyword], and stray Lorem ipsum. These are the fingerprints of a template run at scale.
3. Pages built around ads. A short article broken up by a dozen ad slots, autoplaying video and "recommended content" grids. The text exists to hold the ads in place.
4. Stock people. Authors, reviewers or testimonials from John Doe and Jane Smith, or the same headshot across unrelated sites.
5. No one behind it. Long articles with no author, no about page and no way to contact anyone.
6. LLM phrasing throughout. Dense use of the stock phrases covered in the phrases that give away AI-written website copy. Weak on its own, because people write like this too.

One sign rarely settles it, except the first: a pasted chatbot reply is about as close to proof of carelessness as the web offers. The others matter when several appear together.

Why there is so much of it

Generating an article now costs close to nothing, while an ad view or affiliate click still pays something. That gap rewards volume. A single operator can publish thousands of pages across dozens of domains, and only a few need to rank to turn a profit. AI app builders lower the cost of the sites themselves, too.

How search engines are responding

• Google added "scaled content abuse" to its spam policies in 2024: producing many pages mainly to manipulate rankings, however they are made. Google's stated position is that it rewards helpful content regardless of how it was produced.
• Kagi launched SlopStop in November 2025. Users report slop, Kagi's staff review it, and domains judged to be mostly AI slop are labelled and pushed down.
• DuckDuckGo offers a setting to hide AI-generated images, based on public blocklists.

None of these removes slop entirely, so the tools you control still matter.

How to avoid AI slop

• Favour sources with names attached: an author you can look up, an organisation with a history.
• Add a forum or "reddit" to product searches to find people describing real use.
• Exclude known farms and builder domains with -site: operators or blocklists. Our guide to hiding AI-generated sites from search results covers the options.
• Leave quickly when a page is mostly ads and says nothing specific in its first paragraph.

Kitsuvo labels slop separately from AI-built sites, with the evidence it found, such as pasted chatbot text, unfilled template slots or ad density. Slop gets a note, never a block, so you decide what to read. It runs on your computer and sends nothing about your browsing to us.
