Concrete numbers, percentages, and dates are quotable, verifiable, and unambiguous, which makes them low-risk for an AI system to surface and attribute. Studies of generative-engine optimization consistently find that adding statistics and citations improves visibility in AI answers. A page that says 'conversion rose 37% in 2024' is far more likely to be cited than one that says 'conversion improved a lot.'

It scans the page text and counts numeric values, percentages, currency figures, and four-digit years, plus outbound links to recognized authority domains (such as .gov, .edu, major research and news sources). It then normalizes those counts per 100 words to give a density score, so a long page is not unfairly rewarded over a concise, fact-dense one.

As a rough benchmark, aim for at least one to two meaningful statistics per 100 words on data-driven pages, with several outbound citations across the article. Very low density (zero stats across hundreds of words) signals thin, opinion-only content. Extremely high density can read like a spec sheet, so the goal is well-integrated, sourced figures, not number-stuffing.

Citations carry more weight when they point to credible, primary sources — government agencies, universities, peer-reviewed research, and established publications. The scorer recognizes common authority signals in link domains. Linking your claims to such sources both strengthens the citation count here and builds the trust that AI systems and readers look for.

Statistics help, but they work alongside topical authority, freshness, and clear structure. A fact-rich page that is also well-organized and answer-first is the strongest combination. Use this scorer to fix the data-density gap, then check structure with our Answer-First Scorer and run brand-citation checks to confirm you are actually being surfaced.

No. It detects the presence and density of numeric and citation patterns, not their truthfulness. You are responsible for ensuring every figure is correct and properly sourced. Inaccurate statistics damage trust and can get content discounted, so always cite a primary source for each meaningful number you publish.

A word counter measures volume and readability tools measure ease of reading. This tool measures evidence density — how much of your content is backed by concrete data and sources. A page can be highly readable yet make no verifiable claims; this scorer surfaces that gap so you can add the proof AI engines reward.
