AI Authority (AA) is a metric from 0 to 100 that says how much a given AI engine leans on a given source. 100 is the source that engine cites most.

It is a count put on a scale, and nothing else: the detections of a source over a rolling 30-day window, measured against the detections of the source that leads its engine. There is no constant to calibrate and no weighting to arbitrate, which is what makes a movement attributable.

Three properties are worth knowing.

- **The 100 comes from the whole corpus.** It is the leading source of every survey run on the platform, not the top of the list you happen to be looking at, so a source at 61 keeps its 61 as your own coverage widens, and your number means the same as your neighbour's.
- **One scale per engine.** Each engine has its own leader and therefore its own 100. Two engines' rankings are close to disjoint, and one AA per engine keeps that relief.
- **A cited source is never zero.** A source the engine cited in the window shows at least 1, however far below the leader it sits. A source it did not cite has no AA at all: absent is not zero.

AA ranks, which is what turns a list of sources into an order of work. Full definition on [the AI Authority page](https://epovest.com/en/ai-authority).
