Generative Engine Optimization

A Georgia Tech and Salesforce AI Research study (NAACL 2025) found that You.com, Perplexity AI, and Bing Chat miss around half of the core sub-questions in a complex query. What sub-question coverage is and how to structure your content to close the gap.

A UC Berkeley study (ACL 2024) found that AI models ignore text style and reward direct relevance to the question. What this means for your content.

A University of Tokyo study measured that reorganizing a text's structure, without changing a single word, raises AI citation rate by up to 17.3%.

A Toronto study measured that AIs cite content up to 52% fresher than Google. With nostosgeo.app's real case: adding a dated sitemap raised its Freshness score from 68 to 82.

A Toronto study measured that AI barely relies on your site for popular topics (91% match with what it already knew) and relies on it almost entirely for specific ones (56%). What to do with that gap.

Google is explicit: of the four components of E-E-A-T, one outweighs the other three combined. What an AI needs to see to cite you as a trustworthy source.

Each AI engine feeds on different sources, but most of what you can do about it pays off the same across all of them. Why chasing each engine separately benefits whoever sells you the monitoring dashboard more than it benefits your site.

Schema.org is the format a site uses to declare what entity it is, instead of leaving a system to infer it from the text. 44% of active sites have no structured markup at all (Web Almanac 2024).

Having lots of content doesn't guarantee AIs will cite you. Aggarwal et al. (KDD 2024) measured that citations, quotations and verifiable statistics together raise source visibility by over 40%.

Share of Model measures how often an AI mentions your brand when answering questions about your industry — and it has nothing to do with your Google ranking.

If your competitor shows up in ChatGPT and you don't, it isn't luck. It's structure: what makes an AI able to identify you as an entity rather than anonymous text.
