How to Check Blog Content for AI
What to watch for when checking blog content for AI:
- Keyword-heavy but insight-thin — many words, little original take.
- Formulaic intro-body-conclusion with heavy signpost transitions.
- Generic advice that could apply to any brand or topic.
- No first-hand experience, specific examples, or original data.
- Even, frictionless rhythm with no authorial voice.
Google does not penalise AI writing. It penalises this.
The premise behind most "AI content checkers" for publishers is wrong. Google's stated position is that it rewards helpful content regardless of how it was produced, and acts against content produced primarily to game search rankings. Those are different things, and confusing them leads people to fix the wrong problem.
The rule is scale plus unhelpfulness, not authorship
What gets hit is mass-produced pages with no first-hand insight — near-identical articles spun from one template, thin coverage of a topic already covered better elsewhere, text written for a crawler rather than a reader. A model makes producing that easy, which is why the two get conflated.
Templated multilingual output is a common trap
One page cloned across dozens of languages, each a machine translation of the same thin original, is the pattern most likely to be treated as scaled abuse. Fewer pages that are genuinely written for their audience outperform many that are not.
What "helpful" concretely means
Something the writer knows that a summariser could not: original data, a test you ran, a mistake you made, a specific recommendation with the reasoning behind it. Pages without any of that struggle whether a person or a model typed them.
So what is a detector for here?
As an editorial check, not a compliance one. A high score on a draft usually means the piece has drifted into generic summary — useful as a prompt to add something concrete. Deleting a good article because a tool returned 80% would be the wrong move.
We say this from experience rather than theory: this site was itself hit by an algorithmic demotion, and the fix was not removing AI assistance — it was removing self-serving markup, cutting duplicated multilingual pages, and making each page say something the others do not.
