Differentiation Opportunity
- Product differentiation: this is not a grammar checker and not an AI detector; it is an AI cliche / style tic checker.
| Keyword | Volume/mo | KD | CPC | Read |
|---|---|---|---|---|
| ★ signs of ai writing | 1,300 | 18 | $3.31 | The measured winner: +494% yearly (260 → 2,400/mo over the year), KD 18, and the page-1 incumbents are ALL articles — not one tool. Paste-and-check is a differentiated result type here. |
| ai writing checker | 8,100 | 74 | $3.31 | Codex's pick — 8,100/mo but KD 74: Grammarly-class domains with 20K+ backlink profiles. A year-2 ambition, not the entry point. |
| em dash chatgpt | 1,600 | 25 | — | The em-dash meme — still 1,600/mo but collapsing (-87% yearly). Worth one FAQ page, not a foundation. |
| ai buzzwords | 390 | 2 | $19.53 | KD 2 with a $19.53 CPC — the cheapest ranking real estate in this report, and advertisers pay B2B money on it. |
| not x but y / ai words to avoid | 200 | 13 | $1.00 | The Atlantic's 'negative parallelism' vocabulary entering search: `not x but y` +600% yearly, `ai words to avoid` +75%. Small today, riding the exact wave this report was picked for. |
| ai humanizer / humanize ai text | 823,000 | 63 | $3.40 | Measured for the record: 823K/mo. Deliberately NOT our lane — KD 49–72, a bypass-detection red ocean, and exactly the ethics DECISION rules out. The road not taken, on purpose. |
SERP breakdown: signs of ai writing (Google US, measured 2026-07-15)
| # | Result | What it is |
|---|---|---|
| 1 | Wikipedia:Signs of AI writing | The Wikipedia editors' official field guide — the list everyone cites |
| 2 | Reddit r/AskReddit | 750+ comment thread (4 months old) |
| 3 | Substack (Sean Kernan) | A personal newsletter with 19.4K likes at #3 |
| 4 | huntingthemuse.net | Indie writing blog |
| 5 | wanderingeducators.com | Indie education blog |
| Social | Perspectives pack ×12 | The Atlantic + this week's viral posts: LinkedIn 19 hours ago, Instagram 5–8 days ago, YouTube Shorts |
| PAA | 4 questions | Citing Wikipedia/Pangram/university library guides |
| 6-8 | eLearning Industry, a library guide, another Substack | More articles, lists, guides |
Two key findings: (1) No AI Overview — Google isn't AI-answering 'how to spot AI writing' yet, so page-1 clicks aren't being skimmed; (2) zero tool sites — every incumbent lists the signs, none lets you paste text and check against them. Wikipedia's list is a ready-made public rules corpus, and an Instagram creator is farming engagement by gating the exact fix-it prompt behind comments (liz.on.the.web, 1 week ago) — the demand is already proven by someone else; nobody has shipped the tool.
Verdict: the best growth curve in the archive — a rising head term, article-only incumbents, and the tool slot empty. Publish this week.
ai writing checker at KD 74 is Grammarly country. Also deliberately skip the humanizer family (823K/mo of temptation, but it's the bypass-detection red ocean and the exact ethics line DECISION drew).not x but y +600%; ai words to avoid +75%. Contrast: samsung-health's cluster was flat all year and the family report rode a news pulse. This is the first report whose baseline itself is growing.Target User
