Quantitative evidence is a numerical finding used to support a claim, whether original or properly sourced. This factor combines two related strengths in the accepted list: a distinctive primary result and a checkable number. A percentage without its population, method, or date is not meaningful evidence. A small, carefully documented dataset can be more useful than a large but opaque statistic. [Google's helpful-content guide](https://developers.google.com/search/docs/fundamentals/creating-helpful-content) and [review guidance](https://developers.google.com/search/docs/specialty/ecommerce/write-high-quality-reviews). ## Impact details **Impact: Medium, conditional on relevance and reliability.** Original measurements can answer questions that generic summaries cannot and give another writer or AI system a concrete finding to reference. Google highlights original research and analysis in its helpful-content questions and recommends quantitative measurements for reviews. Bing advises examples, data, and cited sources to support claims reused in AI-generated answers. These sources support the value of evidence-rich content, not a universal citation boost from adding numbers. Irrelevant or poorly measured statistics can weaken trust and lead to inaccurate summaries. [Google's helpful-content guide](https://developers.google.com/search/docs/fundamentals/creating-helpful-content), [review guidance](https://developers.google.com/search/docs/specialty/ecommerce/write-high-quality-reviews), and [Bing's AI Performance guide](https://blogs.bing.com/webmaster/February-2026/Introducing-AI-Performance-in-Bing-Webmaster-Tools-Public-Preview). ## Proof & consensus details **Proof: Medium. Consensus: Mixed** for direct AI visibility. Google and Bing both advocate original information and evidence, and Bing explicitly mentions data when discussing AI citations. The public guidance does not quantify how much an original dataset changes selection across providers, nor does it distinguish useful data from decorative numbers through a simple rule. Originality can be valuable, but credibility depends on sample selection, measurement, definitions, and reproducibility. A number copied from another source is not proprietary research and should be attributed. Treat causal claims with particular care: correlation or a before-and-after observation alone may not establish why an outcome changed. [Google's helpful-content guide](https://developers.google.com/search/docs/fundamentals/creating-helpful-content), [Bing's AI Performance guide](https://blogs.bing.com/webmaster/February-2026/Introducing-AI-Performance-in-Bing-Webmaster-Tools-Public-Preview), and [Bing Webmaster Guidelines](https://www.bing.com/webmasters/help/bing-webmaster-guidelines-30fba23a). ## Recommendation Publish the finding together with enough method for a reader to interpret it: what was measured, when, by whom, on which sample, and with which definitions. State units, denominators, uncertainty, and exclusions near the figures. Make tables or downloads available where feasible, with privacy and contractual limits respected. Link numerical claims to the relevant section of the study or primary dataset. Explain what the data supports and what it cannot show. Prefer a smaller set of meaningful measures over a page filled with uncontextualized percentages. Update figures when the underlying system or market materially changes. ## AI platforms **Google AI Overviews and AI Mode** can draw on Search pages containing original, useful evidence; Google provides no data-specific citation guarantee. [Google's AI optimization guide](https://developers.google.com/search/docs/fundamentals/ai-optimization-guide) **Bing and Copilot** explicitly recommend data and cited sources to support claims in AI answers. [Bing's AI Performance guide](https://blogs.bing.com/webmaster/February-2026/Introducing-AI-Performance-in-Bing-Webmaster-Tools-Public-Preview) **ChatGPT** has no published scoring rule for proprietary statistics. For any provider, check whether a generated answer quotes the right number, denominator, period, and source rather than merely citing the page. [OpenAI's publisher FAQ](https://help.openai.com/en/articles/12627856-publishers-and-developers-faq) **Claude:** Anthropic describes evaluating Research outputs for source quality, including use of primary sources. Original studies can serve that role, but the evaluation is not a publisher ranking formula. Verify that cited numbers retain their population, period, and method. [Anthropic’s Research system explanation](https://www.anthropic.com/engineering/multi-agent-research-system). **Perplexity:** Deep Research is described as finding primary sources and citing claims. That makes original evidence relevant to research tasks, without guaranteeing preference for a particular dataset. Check that the answer preserves the measurement and its limitations. [Perplexity Deep Research](https://www.perplexity.ai/en-GB/hub/products/deep-research). ## Audit instructions 1. List the main numerical claims on priority pages and identify which are original measurements and which come from outside sources. 2. For each figure, check its source, date, sample, denominator, units, and method. Flag claims whose meaning or reliability cannot be assessed. 3. Add missing context or correct the number, then verify the rendered page. Compare any AI summary with the exact figure and its limitations.
