GEO Times changelog

A chronological record of which questions GEO Times has measured and how its reporting methods have changed.

We log new AI search measurements, changes to the measurement method, and changes to editorial standards here. When an article is corrected, the correction and its date are also shown on the article itself.

September 2026

September 2, GEO Times launches

GEO Times took its first step at geotimesnews.com.

Our main beat is measuring and recording which companies and brands generative AI search recommends and which websites it cites as sources.

The engines measured are the major generative AIs, including ChatGPT, Gemini, Perplexity and Claude. We do not judge from a single answer; measurement begins by repeating the same question several times and checking whether a company appears and which sources are cited.

Alongside the launch we published About GEO Times and our reporting and measurement standards.

Articles carry a type label so their nature is clear: international developments, measured, comparison, guide, experiment and opinion. Measured articles state the date, AI engine, question and number of runs by default.

Measurements starting in September

The first regular measurement starts with questions about Korean GEO vendors.

We select questions a real user would use when looking for a vendor, such as "recommend a GEO agency" or "generative AI search optimization company", and enter them identically into the major AI engines. We will record which vendors appear repeatedly and which web pages each engine presents as evidence.

Rather than a one-off, we will measure the same questions again over a period and look at how the results change.

We will also cover AI search news and research from Google, OpenAI, Perplexity and others, checking the original, summarizing the main points in Korean and showing the source.

English editions of articles will follow.

September 5, first six articles

We published five international news summaries and one guide, in Korean and English.
