Thin content is any page that doesn’t give readers or search engines a real reason to exist — a post that’s technically about a topic but adds no original insight, no evidence, and no first-hand expertise beyond what a dozen other pages already say. AI prompts can’t fix thin content by themselves, but they’re genuinely useful for the first, tedious step: finding which of your pages are actually thin before you decide what to rewrite, merge, or remove.
What Does Google Actually Mean by “Thin” or “Unhelpful” Content?
Google’s own developer documentation on creating helpful content frames the question around whether content is “people-first” rather than “search-engine-first.” It lists explicit warning signs of search-engine-first content, including content produced at scale across many topics with little added value, heavy reliance on automation without a person adding insight, and content that mainly summarizes what others have already said without offering anything extra.
Google frames this through what it calls E-E-A-T — Experience, Expertise, Authoritativeness, and Trustworthiness — with trustworthiness described as the most critical of the four. The guidance is blunt about the questions to ask: does the content provide original information, research, or analysis; is it comprehensive; would a reader bookmark it or recommend it to a friend?
The Core Prompt: Scoring a Page Against Google’s Own Questions
Instead of asking AI to vaguely “grade” a page, feed it Google’s actual published self-assessment questions and your content, so the scoring is grounded in a real published standard rather than an invented rubric:
“Here is the full text of one of our blog posts: [paste content]. Evaluate it against these questions, answering each one directly with evidence from the text: Does it provide original information, research, or analysis beyond the obvious? Is it comprehensive and substantial on its topic? Does it demonstrate clear sourcing or first-hand expertise? Would a reader likely bookmark or recommend it? Based on your answers, classify the page as Strong, Borderline, or Thin, and explain the single biggest gap.”
A Prompt for Triaging a Whole List of URLs at Once
Once you know what “thin” looks like on one page, scale the same logic across a list pulled from your analytics or CMS export:
“Here is a list of blog post titles, word counts, and publish dates: [paste list]. Based on title and word count alone, flag any posts under [word count threshold] words or with titles that suggest overlap with each other as candidates for a manual thin-content review. Group likely duplicates or near-duplicates together so I can decide whether to merge them.”
Fix, Merge, or Remove: A Prompt for Deciding What to Do Next
Flagging thin pages is only half the job — each one needs a decision. This prompt forces a specific recommendation instead of a vague “improve this”:
“This page was flagged as thin content: [paste content or summary]. Recommend one of three actions — (1) Rewrite: expand it with specific original detail, and list exactly what’s missing; (2) Merge: name a stronger existing page on our site it should redirect into; (3) Remove: explain why it likely isn’t salvageable. Justify your recommendation in two sentences.”
What AI Genuinely Can’t Do Here
- It can’t supply the first-hand experience or original research that separates strong content from thin content — that has to come from you
- It can’t reliably judge factual accuracy in a specialized field without a subject-matter expert checking its output
- It can’t see your actual traffic, conversion, or backlink data unless you paste it in, so its triage is only as good as what you feed it
Once you’ve flagged thin pages, pair the fix with the workflow in refreshing old blog posts, and use content briefs to make sure the rewritten version is planned to be comprehensive from the start.
Frequently Asked Questions
How many words counts as “thin content”?
There’s no official word-count cutoff from Google. A 300-word page can be genuinely helpful if it answers a narrow question completely, and a 2,000-word page can still be thin if it’s padded and repetitive. Google’s own guidance focuses on whether the content is comprehensive and original for its specific topic, not on hitting a length target.
Can AI-generated content ever pass as “helpful content” under Google’s guidelines?
Google’s guidance doesn’t ban AI assistance outright, but it explicitly flags “extensive automation to produce content on a number of topics” without human oversight as a red flag. The safest approach is using AI to draft or research while a knowledgeable person adds real analysis, verifies facts, and takes ownership of accuracy.
Should I delete thin pages or try to fix them?
It depends on the page. If it targets a topic your audience genuinely searches for, rewriting it with real depth is usually the better long-term move. If it’s a near-duplicate of a stronger page you already have, merging and redirecting it typically consolidates authority better than maintaining two competing thin pages.
