Job aggregator
Definition
A job search site that collects vacancies from many sources, like careers pages and job boards, and shows them in one place.
A job aggregator doesn't wait for you to post a job there. It goes out and collects jobs itself, by crawling careers pages, pulling in feeds from job boards and ATS systems, and putting everything in one big searchable list. For the job seeker it's handy, one search instead of ten sites. For you it means your vacancy can end up in places you never posted it.
That sounds like free reach, and partly it is. But there's a catch. Aggregators usually show the free listings lower and sell visibility on top, often per click. And when your job gets pulled in from a messy feed, it can show up with the wrong title, an old salary or a broken link, and you won't even know. So it's worth checking where your jobs actually show up, and what they look like there.
The line between a job board and an aggregator is blurry these days, a lot of sites do both. The question to ask is simple: did I put this job here, or did they take it?
Example
A recruiter searches for one of their own open roles on a big aggregator and finds it listed three times: once from their careers page, once from a job board and once from an old feed with last year's salary. They clean up the feed, make sure the careers page is the one source of truth, and the duplicates disappear.
