GEO Source Credibility Checker - Verify Your Citations
AI engines prioritize verifiable facts. Score your content's source credibility by analysing outbound links, detecting high-authority domains, and extracting dense statistical data.
How to verify your GEO credibility
Paste your HTML
Copy the rich text or raw HTML of your article, including any <a> tags and blockquotes, and paste it into the analyzer.
Check your citations
The tool extracts all outbound links, evaluating them for high-authority (.edu/.gov) vs low-quality (UGC) domains.
Verify data density
Review the extracted statistics and expert quotes. High data density strongly correlates with AI citation eligibility.
Why source citations dominate GEO
The AI Fact-Checking Protocol
Retrieval systems in ChatGPT and Perplexity actively check the outbound links on a scraped page to verify its accuracy. A page discussing medical AI with zero links to PubMed or institutional research is treated as an opinion, not a citable fact.
Data Density Wins
AI models love numbers. Extracting "85% reduction" or "1.5x speed increase" is far easier for an AI to synthesize than vague qualitative statements. High statistical density acts as a clear signal of objective, research-backed content.
Primary > Secondary
Linking to another blog covering a statistic weakens your GEO profile. You must link to the original data source. AI models can map the citation graph; being one hop away from the primary research makes your content the preferred "node" to cite.

Frequently asked questions
Why is my score so low if I have a lot of internal links?
Internal links are great for classic SEO, but GEO (Generative Engine Optimization) evaluates you as a credible source. A credible source cites *external*, third-party references to back up its claims. A purely self-referential site scores poorly for objective credibility.
Does linking to Wikipedia hurt my GEO score?
Yes. AI engines are trained to prefer primary sources. Wikipedia is a secondary source (User-Generated Content). While Wikipedia itself ranks highly, citing it weakens your E-E-A-T profile because it suggests a lack of deep research. Always cite the primary source Wikipedia references.
How many outbound links should I have?
A good target is 2-4 high-quality outbound citations per 1,000 words. However, the *quality* and *relevance* of the links matter significantly more than the raw count. Linking to an .edu study provides massively more GEO benefit than linking to a lifestyle blog.
What does the tool mean by "Statistics & Data"?
The tool scans your text for statistical patterns (percentages, exact monetary values, comparative ratios). Studies show that content with a high density of verifiable numbers is far more likely to be cited by Perplexity and Google's AI Overviews than qualitative "fluff".
Can this tool parse Markdown?
No, this specific tool requires HTML (e.g., using <a href="..."> tags) to correctly extract the domain names and verify standard web syntax for outbound links. You can copy rich text from Word or Google Docs directly into the tool.
