Perplexity AI has rolled out a significant update to its business citation algorithm in May 2026, with changes that directly affect how businesses appear — or fail to appear — in AI-generated search answers.

The update, which Perplexity has not formally announced but which has been observed across thousands of queries, appears to place significantly greater weight on structured identity records when deciding which businesses to cite in response to commercial queries.

What Changed

Prior to the update, Perplexity's citation algorithm weighted general web presence heavily — businesses with many mentions across news sites, directories, and review platforms tended to appear frequently in answers. The updated algorithm appears to apply a verification filter: businesses with cryptographically verifiable identity records, consistent JSON-LD schema markup, and government registry anchors are being cited more frequently and with greater confidence.

Businesses without these signals are increasingly being omitted from answers or cited with hedging language such as "according to its website" — a phrase that signals to users that the information has not been independently verified.

The Practical Impact

For businesses that have already registered with identity verification services such as AI Verified, the update is likely to be positive. For businesses that have not yet taken steps to establish a structured identity record, the update represents a meaningful reduction in AI visibility.

"This is the direction the entire AI search industry is moving," said one digital marketing analyst. "The question is no longer whether AI systems will require verified identity records — it is how quickly businesses need to act to avoid being left behind."

What Businesses Should Do

Businesses seeking to maintain or improve their visibility in Perplexity and other AI search systems should take three immediate steps: register with a recognised business identity registry, add Organisation JSON-LD schema to their website, and publish an llms.txt file at their domain root. These three actions create the structured identity signals that Perplexity's updated algorithm is now prioritising.
