What counts as a verifiable fact?

Verifiable facts include concrete numbers and statistics, named sources and references, specific examples and case studies, dates and times, and concrete comparisons. General claims like "many companies" or "significant improvement" do not count.

What is a good fact density score?

A score of 5-7 per paragraph is good for most content types. Academic content and in-depth articles should aim for 7-10, while creative content and opinion pieces can be lower. The tool provides benchmarks based on your content type.

Can too high fact density be negative?

Yes, content overloaded with numbers and statistics without narrative can be hard to read. The goal is balance — enough facts to be convincing and valuable, but with enough narrative to be engaging and readable.

Does the tool work on Norwegian text?

Yes, the tool analyzes both Norwegian and English text. It recognizes Norwegian phrasings, number formats and source references and provides relevant improvement suggestions in Norwegian.

Fact Density Checker

What it does

Analyzes how many verifiable facts the text contains per paragraph. Helps you write more substantive content.

Your content sounds good — but actually says nothing substantive the reader can use

Much of the content on the web is "fluffy" — it uses many words without conveying concrete information. Sentences like "we offer market-leading solutions" and "our innovative approach ensures results" sound professional but contain zero verifiable facts. Readers — and Google — recognize this and reward content with high fact density: concrete numbers, specific examples, named sources and verifiable claims.

Generic claims without evidence convince nobody — "we are the best in the industry" without numbers, comparisons or sources is empty content that readers scroll past
Low fact density signals low expertise — Google E-E-A-T evaluates whether content shows experience and expertise, and content without concrete facts scores poorly
Competitors with higher fact density rank better — studies show that top-ranked pages have 2-3x more verifiable facts per paragraph than lower-ranked pages
It is hard to evaluate your own content objectively — you know what you mean, so you do not notice when the text lacks the concrete details the reader needs

Objective analysis of fact density in your text — with concrete suggestions for improvement

Fact Density Checker analyzes your text paragraph by paragraph and counts the number of verifiable facts — numbers, statistics, named sources, specific examples and concrete claims. You get a fact density score for each paragraph and the entire text, with highlighting of "fluffy" paragraphs that need more substance and concrete suggestions for what facts you can add.

Paragraph-by-paragraph analysis: each paragraph gets a fact density score based on the number of verifiable facts — so you see exactly where the text is strong and where it is weak
Fluffy detector: the tool identifies generic claims, vague phrasings and contentless sentences that drag down the quality of the text
Improvement suggestions: for each weak paragraph the tool suggests specific types of facts you can add — numbers, sources, examples or comparisons
Benchmark comparison: see how your fact density compares to top-ranked pages for the same topic — so you know if you need more substance

Features

Fact density score: each paragraph gets a score from 0-10 based on the number of verifiable facts — numbers, statistics, named sources, specific examples and concrete claims
Fluffy highlighting: generic sentences like "we are leading" and "our innovative solution" are highlighted in yellow so you can replace them with concrete facts
Fact type analysis: the tool categorizes your facts — numbers/statistics, sources/references, examples/case studies, comparisons — so you see which types you are missing
Competitor benchmark: compare your fact density with top 10 results for the target keyword — see if you need more numbers, sources or examples to compete

How it works

Paste the text you want to analyze — it can be a blog post, a landing page, a product description or any other text you want to improve
Get a detailed analysis with fact density score per paragraph, highlighting of fluffy content and categorization of the facts you already have
Use the suggestions to strengthen weak paragraphs with concrete numbers, sources, examples and comparisons — and see the score increase in real-time

Use cases

SEO content writers who want to increase rankings by producing more substantive content with higher fact density than competitors
Editors quality-checking articles before publication who need an objective measurement of whether the content is substantive enough or too generic
Marketers writing landing pages and product descriptions who want to replace vague claims with convincing facts that increase conversion rates

Why use Fact Density Checker?

In a world where AI can generate thousands of words in seconds, fact density is what separates valuable content from generic filler. Google rewards content that demonstrates E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness), and concrete facts are the most direct way to demonstrate expertise.

The tool gives you an objective assessment that is impossible to get yourself. When you write about something you know well, the text feels substantive because you know what you mean. But the reader only sees the words — and without concrete numbers, sources and examples the content remains vague and unconvincing.

For SEO, fact density is a competitive advantage. When you compare your text with top-ranked competitors and see that they have twice as many facts per paragraph, you know exactly what you need to improve to compete for the top position.
