The Sourceability Score analyzes your content to identify claims that need supporting evidence and evaluates how well your current sources back up your statements. In an era of AI fact-checking and credibility assessment, properly sourced content is essential for trust and citation potential.
This tool scans your content for factual claims, statistics, and statements that require evidence, then checks whether adequate sources are provided. It identifies unsupported claims that could undermine credibility and suggests appropriate source types for each claim.
Beyond identifying gaps, the tool provides specific citation opportunities, showing where adding sources would most improve credibility. This is particularly valuable for content that aims to be authoritative and frequently cited by both humans and AI systems.

Sourceable content has clear evidence for all factual claims, uses credible external sources, links directly to supporting data, and maintains a good ratio of sources to claims. This makes it trustworthy for both readers and AI systems.
Aim for at least one source for every 2-3 major claims or statistics. Long-form content (2000+ words) typically needs 5-10 external sources. Quality matters more than quantity - use authoritative, relevant sources.
Primary sources (original research, official data), authoritative institutions (.gov, .edu), peer-reviewed studies, and recognized industry experts are most credible. News sites and blogs can support opinions but shouldn't be sole sources for facts.
Yes, proper sourcing improves E-E-A-T signals, which Google considers for rankings. Well-sourced content also earns more backlinks, gets cited more often, and builds domain authority - all positive ranking factors.
