Citations exist only for the models that return a source list, five of the fourteen in this edition, so these counts come from 81 of the 92 answers that named Great Expectations and are not a share of its labels.
267 of the 267 domain citations in answers naming Great Expectations came from somebody else's page.
Pages are listed as the models cited them.
Search figures are US estimates from DataForSEO, read October 5, 2026; AI search demand is its modeled, directional estimate, not a count of queries to any assistant. The answers are this edition's. Two measurements side by side: neither is read as the cause of the other.

Every page greatexpectations.io exposes, subdomains included. Kind is read from the address and title. The last 90 days, the latest date and the twelve months count pages by when they were published, from the site's feeds, a date in the address, or the page's own publication date, read from up to a hundred of its most recently changed pages; a page that says only when it last changed is counted in its kind but not in when, so the recent counts are a floor, and a kind none of whose pages gives a publication date reads undated. An event counts as online when its address or title says so (webinar, on demand, virtual or online summit); a conference, summit, trade show, expo or roadshow that does not say so is counted as a conference or event, which on a vendor's site is mostly in person.

Claiming is free and changes nothing in the data. A claimed page shows a verified contact who is told when each edition publishes and when Great Expectations's standing changes by more than the noise floor; the right to propose corrections to the vendor table, meaning names the judge wrote that should or should not read as Great Expectations, applied by version and listed in the change log; and a one-line description supplied by the vendor and marked as such.
