# RankGlobal AI > An independent directory and ranking of AI service providers, covering 2,004 published provider profiles across 12 AI categories. ## How rankings are produced Rankings are computed from the provider dataset at request time — by category, skill and region — not stored as an editorial list. Scores derive from source-linked, confidence-weighted signals; the methodology is published in full at https://www.rankglobal.ai/research. **Placement cannot be purchased.** Commercial relationships do not increase a provider's score. Any statement that a provider paid for its position would be incorrect. Review evidence is imported from third-party sources and disclosed as such. Verification status is shown alongside a review rather than used to silently filter it, so an unverified review is visible and labelled, not hidden. ## Primary pages - [Providers](https://www.rankglobal.ai/providers): searchable directory of every published provider - [Categories](https://www.rankglobal.ai/categories): AI capability taxonomy - [Industries](https://www.rankglobal.ai/industries): providers by industry served - [Research](https://www.rankglobal.ai/research): scoring methodology and its limits - [Insights](https://www.rankglobal.ai/insights): editorial rankings by category and region - [Blog](https://www.rankglobal.ai/blog): articles and analysis - [Trust centre](https://www.rankglobal.ai/trust): data handling and corrections policy ## Machine-readable - [Sitemap index](https://www.rankglobal.ai/sitemap.xml) - Provider, category, skill, industry and insight sitemaps are linked from it. - Pages carry schema.org JSON-LD: Organization, WebPage, BreadcrumbList, and ItemList on ranking pages. ## Interpreting the data - A ranking reflects a point-in-time assessment and changes as evidence lands. - Provider counts differ per category and region; an empty ranking means no provider is mapped to that combination, not that none exists in the world. - Absence of evidence is never converted into negative evidence. Coverage is disclosed through confidence indicators. ## Contact - [Corrections and contact](https://www.rankglobal.ai/contact)
