Entity Corroboration is the process of getting third-party sources across the web to confirm and reinforce the factual information you state about your brand on your own website, or Entity Home.

Jason Barnard uses the term Entity Corroboration to explain that algorithms, like people, do not simply take your word for it; they require independent verification to build trust. After you define your brand's narrative on your Entity Home (the single source of truth for an entity, typically the About page on its official website), corroboration is the process of getting other trusted websites and platforms to repeat and confirm that information. When multiple credible sources echo the same facts, an algorithm’s confidence in those facts increases significantly. This process is fundamental to educating AI systems like ChatGPT, Bing Copilot, and Google AI about your brand's identity, preventing misrepresentation and building the algorithmic trust necessary to control your narrative.

At Kalicube, systematically building Entity Corroboration is a central pillar of The Kalicube Process, Kalicube's proprietary methodology for implementing a holistic, brand-first digital marketing strategy. After establishing the client's Entity Home as the single source of truth in Phase 1 (Understandability), we focus on building a network of corroborating sources in Phase 2 (Credibility). We identify and optimize trusted first-, second-, and third-party platforms to ensure they consistently echo the core facts about the client. This methodical approach is designed to "educate" AI systems, increasing their confidence in the entity's facts and making our client's website the definitive, trusted reference. This verification is how our clients' narratives become not just self-proclaimed, but algorithmically validated, which is essential for driving business goals.

For decades, marketers have understood the power of Robert Cialdini's principle of Social Proof: people look to the actions and endorsements of others to determine what is correct. In the pre-AI digital world, this meant gathering testimonials and media mentions to influence potential customers. However, AI Assistive Engines like ChatGPT and Google AI Overviews have introduced a new, non-human audience that also needs to be convinced. Jason Barnard's concept of Entity Corroboration translates Cialdini's timeless principle into the practical, technical language of algorithms. It is no longer enough to have scattered social proof; brands must now create a web of interconnected, consistent facts that algorithms can easily verify. Entity Corroboration, as applied in The Kalicube Process, is the technical execution of social proof for machines. By systematically getting authoritative sources to confirm your brand’s story, you provide the algorithm with the digital equivalent of social consensus, making your brand the correct and trusted choice in this new AI-driven acquisition funnel.
