what is ai slop? how to spot it on a website

where the term comes from

"Slop" started as a word for low-effort AI images and articles flooding search results and social feeds. It stuck because it describes the feeling well: food made in bulk, for nobody in particular. Websites got the same treatment once anyone could generate a landing page in a minute.

ai slop is not the same as ai-written

Plenty of good sites are drafted with AI. The difference is editing. A person who knows the product cuts the filler, replaces vague claims with real ones, and makes the page look like their company instead of the default output. Slop is what you get when that step is skipped.

So the useful question is not "did a model write this?" Detectors that try to answer that are unreliable. The useful question is "does this page say anything specific?"

how to spot it in the copy

• Stock phrases. Words like seamless, unlock, elevate, empower and revolutionize show up in machine-written marketing far more than in human writing. One is fine. Five in a hero section is a pattern. We keep a longer list here.
• No one-sentence answer. Read the headline and the line under it. If you still can't say what the product does and who it's for, the copy is filler.
• Triplets everywhere. "Fast, secure, and scalable." Models love lists of three adjectives. Real products usually have one thing they're best at.
• Claims with no numbers. "Trusted by thousands", "loved by teams worldwide". If the number were real, it would be on the page.
• Sections that answer no question. A "Why choose us" block that repeats the hero in different words is there to fill space.

how to spot it in the design

• A purple-to-blue gradient behind a centered headline.
• Three feature cards, each with an icon, a two-word title and one vague sentence.
• The default font of the template, the default spacing, the default rounded corners.
• Illustrations or "screenshots" that don't show the actual product.
• Logos of companies that have never heard of you.

None of these is wrong alone. Together they make a site look like every other site built the same week, and visitors notice even when they can't say why.

why it matters

Trust. A visitor decides in seconds whether a site is worth reading. Generic copy and a template look signal "side project nobody maintains", even when the product is good.

Conversion. Vague pages make people work to understand the offer. Most won't. A headline that says exactly what you do keeps more of them on the page.

Search. Google's spam policies name "scaled content abuse": pages generated in bulk mainly to rank, with little value for readers. Its guidance rewards content that shows first-hand experience. Unedited AI copy is the opposite of that, and answer engines like ChatGPT and Perplexity have little reason to quote a page that says what every other page says.

a two-minute self-test

1. Cover your logo. Could this page belong to a competitor?
2. Read only the headline and subheadline. Can you say what the product does and for whom?
3. Count the claims with a number, a name or a screenshot behind them.
4. Find one sentence only your team could have written.
5. Look at the colors and fonts. Did anyone choose them, or were they the default?

If you answered "yes, no, zero, none, default", the page is slop, whatever tool made it.

the human signals that cancel it out

The fastest fix for slop is evidence that real people built the thing: real screenshots, real names and faces, specific numbers, a changelog, a price, an opinion. A single sentence only your team could have written is worth more than a page of polished filler.
