How much AI is too much in my content?

Why the percentage is a fantasy

“What ratio is safe” assumes Google is measuring a ratio. It isn’t — there’s no AI-content meter, no documented threshold, and Google has said it doesn’t rank based on how content is produced, only whether it’s helpful. The detector tools you can buy that claim to score “percent AI” are unreliable enough that you shouldn’t trust their number either — false positives on plain human writing, trivially fooled, no agreed standard; more on that on AI-detection tools and the ranking myths around them. So there’s nothing for a percentage to hit. A page that’s 95% AI-drafted and rigorously checked by an expert can be the best answer on the topic. A page that’s 95% hand-typed by someone with nothing to say is filler. The split tells you almost nothing; what the human did with the draft tells you everything.

The test that actually applies

Run the published page — not the draft, the thing that goes live — through four questions:

• Is it accurate? Has someone who knows the subject verified every factual claim, every number, every recommendation? AI confidently states things that are wrong. If nobody fact-checked it, you don’t know if it’s accurate, which means it isn’t ready.
• Is it original? Does it say something — a specific angle, a real example, a first-hand detail — or is it a fluent restatement of the internet’s average take on the topic? Generic is the default failure mode of an unedited AI draft, and generic doesn’t rank because it’s not the best answer to anything.
• Is it genuinely useful? Would a buyer searching for this actually want this page? Does it match their intent and answer it fully? If the honest answer is “not really,” polishing it doesn’t help — no amount of editing fixes a page that has nothing to say. Kill it.
• Does a knowledgeable human stand behind it? Real byline, stated credentials, accountability. “Would someone with expertise in this field recognise this as right?” — and is their name on it? That’s the Experience-and-trust layer AI can’t supply for you, covered on E-E-A-T when AI helped write it and E-E-A-T for service businesses.

Pass all four and the AI percentage is irrelevant. Fail any one and “but it’s only a little AI” doesn’t save it — and “it’s 90% human” doesn’t either. This is also the test for whether adding pages will hurt your rankings: a page that passes earns its place; a page that doesn’t drags the domain’s average down, regardless of who or what produced it.

How we run it

Miss Pepper produces content fast by using AI — and the line above is exactly where we draw it. Senior people set the angle, do the editing and fact-checking, wire the internal links, and stand behind every page; the topical-authority architecture is what makes a hundred pages read as thoroughness rather than a dump. AI is a speed multiplier on that process — it doesn’t replace the brief, the edit, the fact-check, the structure, or the accountability, and it’s the process and the people running it that make the content rank. Bayshore HVAC’s 12 → 184 pages, +312% organic in 90 days, is what that looks like when it’s done right; the pages were genuinely useful and senior-checked, which is why there was no policy problem. That’s the authority-site build, and programmatic SEO is the version for data that fits a template cleanly. Want a read on whether your current content has a real human layer or just performs one?

Stop measuring how much AI is in the page. Start measuring how much judgment is. One has a number that means nothing. The other doesn’t have a number, and it’s the only thing that matters.
