Most advice about getting cited by AI is vibes. "Write quality content." "Build authority." Useful as a fortune cookie. The research is more specific than that, and it puts a number on each move.
Four content changes have measured, repeatable effects on whether an AI engine quotes your page. They come from controlled studies, not opinion, and they rank cleanly from biggest lever to smallest. This post lists all four with the percentage lift each one produces, then shows the exact edit that captures it. No theory you can't act on by Friday.

Where These Numbers Come From
The four citation levers come from generative-engine-optimization research that tested specific edits against AI visibility and measured the change. The original work is the Princeton-led GEO study, and 2026 replications across ChatGPT, Perplexity, and Gemini reported the same hierarchy of effects.
The figures below — 41%, 32%, 30%, 28% — are the visibility lifts those studies attribute to each edit, collected in Mersel AI's 2026 GEO guide. They're directional, not guarantees, and they stack: a page that does all four outperforms one that does none by a wide margin. Brass-SEO's research summary on what the data says about AI search walks through the methodology if you want the underlying study design.
Lever 1: Add Quotations (+41%)
Adding a direct quotation from a named person or source raises AI citation likelihood by roughly 41%, the single largest lever in the research. AI engines treat a quoted expert as a trust signal and lift quote-bearing passages more often than plain assertion.
The fix is concrete. Find the strongest claim on your page and attach a real quotation to it, attributed by name, in the form: According to [expert name], [their credential], [the specific finding in their words]. A named quote beats five paragraphs of your own confident prose, because the engine lifts it whole and the attribution travels with it.
Lever 2: Add Statistics (+32%)
Replacing a vague quantity word with a specific number raises citation likelihood by about 32%. "Many businesses" persuades no one and gets quoted by nothing. "62% of small business sites" is a fact an engine can cite, and it will.
Go through your page and hunt the soft words: most, many, often, significant, a lot. Each one is a missed statistic. Swap in the real figure with its source, and if you don't have the figure, find it or cut the claim. A page dense with specific, sourced numbers reads as evidence, and evidence is what gets pulled into an answer.
Lever 3: Cite Your Sources (+30%)
Linking claims to named, reputable sources raises AI citation likelihood by around 30%. A page that shows its work signals reliability, and engines prefer to cite pages that themselves cite credibly.
This is the easiest lever to capture and the most often skipped. When you state a fact, name where it came from and link it. Studies, official documentation, named reports. The act of sourcing does double duty: it earns the citation lift, and it builds the kind of expertise signal that Google now treats as a prerequisite for AI Mode. Brass-SEO's piece on author bylines and E-E-A-T covers the authorship side of that signal.
Lever 4: Tighten Your Fluency (+28%)
Rewriting for clarity and clean structure raises citation likelihood by roughly 28%. A passage an engine can parse and lift in one clean sentence beats a tangled one carrying the same facts.
Fluency here means the mechanical kind. Short opening sentences that answer the question directly. One idea per paragraph. Headings that match how people ask. The trait Brass-SEO writes about most, the answer capsule, is fluency applied to the first line after each heading: say the citable thing first, support it after. Engines quote the clean sentence and skip the buried one.
How to Apply All Four in Brass-SEO
The Brass-SEO AI Citability button scores a page against these exact traits and tells you which levers it's missing, so a vague "improve my content" turns into "this page has no statistics and no named sources, fix those two." Brass-SEO reads your Google Search Console and Google Analytics data and answers in plain English, which means you ask "which of my pages are closest to citable?" and get a ranked list instead of a research project.
Run your highest-value pages through the Brass-SEO AI Citability button first, since a page already drawing impressions is the fastest to convert into a citation. The score names the missing levers. You add the quote, swap in the statistics, link the sources, tighten the opening lines, and re-check. Both Google Search Console and Google Analytics are required, because the score only matters on pages that already earn search visibility worth protecting. The plan is $25 a month with a three-day free trial, and setup takes about two minutes.
Frequently Asked Questions
Which lever should I start with?
Quotations, at a measured 41% lift, give the biggest single gain, so start there on your top pages. Sources are the easiest to add if you want a quick win first. Doing all four on one page beats doing one across many, because the effects stack on the same page.
Are these percentages guaranteed?
No. They're directional lifts from controlled GEO research, not promises for a specific page. AI citation depends on competition, query, and engine. Treat the numbers as a priority order for where to spend effort, which is how the research is best used.
Does this work for ChatGPT and Perplexity, not just Google?
Yes. The 2026 replications measured the same hierarchy across ChatGPT, Perplexity, and Gemini. The traits are about how any large language model evaluates and lifts text, so a page built this way improves across engines rather than gaming one.
How do I know if my page already has these traits?
Read the first sentence under each heading and ask whether it states a sourced, specific fact. If it hedges or buries the point, you're missing levers. The Brass-SEO AI Citability button scores this automatically and lists what each page lacks, which is faster than auditing by hand.
