How it works

Score your content
in three steps.

The tool analyses your content against the five signals most correlated with AI citation rates. You can run it on any live page or paste content directly — useful for drafts, gated pages, or content you're editing before it goes live.

01
Enter a URL or paste text
For a live page, paste the URL and the tool fetches the content directly. For drafts or content behind a login, switch to text mode and paste your copy. Both routes run the same five-dimension analysis.
02
We score five AI dimensions
The tool checks BLUF structure, answer density, content structure, sentence clarity, and FAQ presence. Each dimension is scored independently so you can see exactly which one is dragging your overall grade down.
03
Get your score and rewrite
Your overall grade (A through F) appears alongside a per-dimension breakdown and a BLUF-rewritten version of your opening sentences. Copy the rewrite directly into your content or use it as a model for the full page.
How scoring works

Five things AI engines
check before citing your content.

Traditional readability tools measure sentence length and syllable count — metrics built for human comprehension. AI readability is a different problem. A model extracting an answer from your page cares about answer location, answer density, and structural clarity. These five dimensions capture what actually predicts citation rate.

BLUF Structure
30% of score
Does the page state its main answer in the first two sentences? LLMs weight the opening 50–80 words 4–8x more heavily than the rest of the page when extracting a quotable response. A page that opens with context-setting background before getting to the point will consistently lose citations to a page that leads with the answer.
Quick fix
Rewrite your H1 and opening sentence so that together they answer the page's primary question directly. The supporting detail can follow.
📊
Answer Density
25% of score
The ratio of direct, specific answers to total word count. A 2,000-word page with 400 words of genuine answers scores higher than a 600-word page with 100 words of answers. Filler, transition paragraphs, and brand storytelling dilute density — which is why long-form content often underperforms shorter, denser pages in AI citation tests.
Quick fix
Cut every sentence that doesn't add a new fact, clarification, or example. Then check if what remains actually answers the question.
🗂
Content Structure
20% of score
Clear heading hierarchy, scannable bullet points, numbered lists for sequential steps, and logical section flow. Models extract content in chunks bounded by headings and list items. A wall of prose gives the model one undifferentiated block to work from. A page with clear H2s and structured lists gives it clean, citable units.
Quick fix
Every H2 should be answerable as a standalone question. If it reads like a topic label ("Our Approach") rather than a question or answer ("How X works"), rewrite it.
💬
Sentence Clarity
15% of score
Short sentences, plain language, low jargon, and high specificity. Vague declaratives ("our solution drives results") score near zero because they can't be cited as factual claims. Specific statements ("response time dropped from 4.2s to 1.1s after switching to edge hosting") score high because they give the model something concrete to quote.
Quick fix
Run a ctrl+F for the word "solution", "leverage", "innovative", and "seamless". Replace every hit with the specific thing you're actually describing.
FAQ / Q&A Presence
10% of score
Pages with explicit FAQ blocks get cited at 3.2x the rate of pages without them. The reason is structural: a question-and-answer pair is the exact format an LLM is being asked to produce. A page that pre-formats its content as Q&A gives the model a ready-made answer it can extract with minimal transformation.
Quick fix
Add a FAQ section to any page targeting an informational query. Five questions minimum, each answered in 2–4 sentences. Add FAQPage schema to make it machine-readable.
✍️
BLUF Rewrite
Bonus output
Beyond your score, the tool generates a BLUF-rewritten version of your opening sentences. This isn't a generic suggestion — it's a rewrite of your actual content, restructured to lead with the answer. You can copy it directly into your page or use it as a reference for rewriting the rest of the section.
Quick fix
Compare the rewrite against your original. The gap between them is your BLUF deficit — the information your readers (and AI engines) have to dig for before getting the answer.
AI vs traditional readability

Why Flesch-Kincaid
doesn't predict AI citations.

Rudolf Flesch developed his readability formula in 1948 to help the US Army write clearer field manuals. The formula counts syllables and sentence length — a reasonable proxy for how hard a human finds text to read. Copywriters and content teams have used variants of it ever since.

It tells you nothing useful about AI citation rates. A page written at a sixth-grade reading level with short sentences and simple words can still score an F on AI readability if it buries the answer in paragraph six. Conversely, a technically dense page with long sentences can score an A if it leads with a precise, direct answer and structures the rest as clearly labelled sections.

The difference comes down to what's being optimised. Flesch-Kincaid optimises for human comprehension — the experience of reading through a document linearly. AI readability optimises for machine extraction — the ability of a model to locate and quote a specific answer from anywhere in the document without reading the whole thing.

LLMs don't read your page from top to bottom the way a person does. They tokenise it, weight different sections by position and structure, and pull the highest-confidence answer chunk. A page that's structured for that process — BLUF opening, headed sections, FAQ block — performs well regardless of sentence complexity. A page that reads beautifully but puts its conclusions last performs poorly.

Who benefits

Every team publishing content
that should be cited by AI.

Content that scores well on traditional SEO metrics often performs poorly in AI search. This tool is for any team that's noticed the gap — pages ranking on page one that never appear in AI-generated answers.

How to move from a C
to an A without rewriting everything.

Most pages score C or below not because the content is bad but because it's structured for a human reader scanning from top to bottom. Restructuring for AI extraction is usually faster than rewriting — you're moving and reformatting existing content, not generating new ideas.

BLUFLow effortVery high impactRewrite your first sentence to state the page's primary answer directly. If your page is "How to improve Core Web Vitals", your first sentence should be the answer — not background on why Core Web Vitals exist. Move all context-setting to paragraph two or below.
BLUFLow effortHigh impactAdd a TL;DR or key takeaway box immediately below your H1. A 2–3 sentence summary at the top of the page gives AI engines a clean, pre-formatted answer chunk before they process the rest of the content.
Answer densityMedium effortHigh impactDelete your introduction section. Most introductions restate the title, explain what the article will cover, and promise to answer the question — without actually answering it. Cut to the first substantive paragraph and your answer density will jump immediately.
Answer densityMedium effortHigh impactReplace vague claims with specific ones throughout. Audit every paragraph for sentences containing "significant", "many", "some", "various", or "several" — these are density killers. Replace each with the actual number, name, or specific claim.
Content structureLow effortHigh impactRewrite your H2s as questions or direct answers. "Our approach to content marketing" → "How to structure content for AI citations". A heading that answers a question is extractable on its own. A heading that names a topic is not.
FAQ presenceLow effortVery high impactAdd a FAQ section to every informational page. Five to eight questions, each answered in 2–4 sentences. Wrap it in FAQPage schema. This single change consistently produces the largest single-session score improvement for pages that don't already have one.
Sentence clarityLow effortMedium impactFind your three most jargon-heavy paragraphs and rewrite each with concrete nouns in place of abstract ones. "Leverage our synergistic platform capabilities" → "Use the dashboard to schedule, analyse, and export your data." Same meaning, machine-readable.
