Editorial policy

The library on this site is AI-assisted. We say so on every page because it is true, and because a reader deserves to know how a page was made before deciding how much to trust it.

How a page is made

1. Demand first. Every page answers a query or prompt that 99Visibility collected: search keyword data, the prompts we track, and the grounding queries Bing reports for our own site.
2. One intent per page. Pages are planned so that no two compete for the same question.
3. A fixed evidence base. The writer model sees 99Visibility's verified review of the GEO evidence (each claim checked against its primary source), the engines' own documentation, and a list of the only sources it may cite.
4. Automated checks. Every page is checked for unlisted sources, invented links, banned claims and banned phrasing before it is published.

The rules every page follows

• Numbers come from the evidence base, with the source named. If we have no number for something, the page gives none.
• Sources are limited to a verified list of primary documents and studies. No invented URLs.
• No promises of rankings, citations, traffic or scores. Pages separate what a publisher controls from what it does not.
• No invented people, reviews, testimonials, case studies or quotes. Examples are labelled as hypothetical.
• No advice that the evidence contradicts. For example, pages do not tell readers that schema, llms.txt or IndexNow will get them cited; they explain what those are and what the evidence shows.
• No hidden text, cloaking or instructions aimed at AI models, on this site or in anything we recommend.

Byline and dates

Pages are credited to 99Visibility Research, the team that maintains the evidence base. We do not attach a person's name to a page a person did not write. The date on each page is the date the library was last written or reviewed.

Corrections

If a page is wrong, tell us at research@99visibility.com and we will fix it. AI engines change often, so a page can go out of date quickly. See about this site for the experiment this library is part of.
