Synthetic content
Text generated by AI with little human input, verification or original insight. Also called AI slop when published at volume.
In depth
What it really means
The problem with synthetic content is not that a machine wrote it. It is that nothing in it was checked, nothing in it is new, and it exists to occupy a keyword rather than to inform anyone. Detection tools are unreliable, but the underlying quality gap is measurable in other ways.
For AI visibility specifically, this content fails at the reranking stage. It is topically on target and substantively empty, which is exactly what a reranker is built to filter. Publishing it at volume also drags down how your whole domain gets weighted.
How it works
- Content is generated from a thin prompt with no source material.
- It is published with minimal editing or fact-checking.
- Retrieval may pick it up as topically relevant.
- Reranking and reasoning steps discard it for lacking specifics, and the domain’s weight suffers.
Pros & cons
Pros
- AI drafting genuinely speeds up structure, outlines and first passes.
- It lowers the cost of covering necessary but unexciting topics.
- Used with real source material and editing, output can be good.
Cons
- Unedited output damages domain-level trust, not just the individual page.
- It contains no original information, so there is nothing for anyone to cite.
- Factual errors ship silently and get discovered by customers.
Common mistakes
- Judging AI-assisted content by whether a detector flags it, rather than whether it says anything.
- Publishing at volume to cover keywords, which harms the whole domain.
- Generating from a topic rather than from real source material.
- Skipping fact-checking because the draft reads confidently.
Best practices
- Give the model real source material: your data, interview notes, product specifics.
- Add something only you can add: proprietary numbers, customer patterns, a real opinion.
- Fact-check every claim before publication, without exception.
- Publish fewer, better pages rather than covering every keyword.
- Use AI for structure and speed, keep humans on judgment and facts.
FAQs
What is synthetic content?
AI-generated text published with little human input, verification or original insight. Called AI slop when it is produced at volume to fill keyword gaps.
Is AI-written content penalized?
Not for being AI-written. Google’s position is that low quality is the problem, regardless of how it was produced. Content with no original information fails on its own merits.
Why does synthetic content fail in AI search?
It is topically relevant and substantively empty, which is precisely what reranking and reasoning steps filter out. There is nothing specific to cite.
How do I use AI without producing slop?
Supply real source material, add something only you have, fact-check every claim, and publish fewer better pages instead of covering every keyword.
