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.
