A job board is a website where employers post openings directly, and candidates browse or apply on that site. A job aggregator does not host jobs of its own; it collects and indexes listings from many sources across the web, such as job boards, company career sites, and staffing agencies, and presents them in one searchable place.
That single distinction, hosting versus collecting, drives almost everything else: how a job gets in front of candidates, how you pay, and how you should measure results.
What Is a Job Board?
A job board is a destination site built to hold job listings. Employers (or their recruiters) create an account, post an opening, and that listing lives on the board until it expires or is filled. Candidates come to the board specifically to search for work.
Because the employer posts directly, the board controls the listing, the application experience, and the data. Boards can be general (covering every industry) or niche (focused on a role type, industry, or location). Many charge to post, to feature a listing, or to access their candidate database.
If you have compared this model to a more automated approach, our explainer on programmatic job advertising versus traditional job boards breaks down where each fits.
What Is a Job Aggregator?
A job aggregator is a search engine for jobs. Instead of hosting listings, it crawls and pulls postings from thousands of other sites, then organizes them into a single index candidates can search. When a candidate clicks a result, they are usually sent to the original source (the job board or career site) to apply.
Aggregators exist because job seekers do not want to check dozens of sites one at a time. By concentrating listings in one place, an aggregator becomes a high-traffic entry point, which is exactly why it matters for employers trying to be found.
Job Board vs Job Aggregator: A Side-by-Side Comparison
| Job Board | Job Aggregator | |
|---|---|---|
| What it is | A site that hosts job listings | A search engine that indexes jobs from other sites |
| How jobs get there | Employers post directly on the site | Listings are crawled, fed, or pulled from job boards and career sites |
| How you pay | Often a posting fee, featured-listing fee, or subscription | Often performance-based (cost per click or cost per applicant), plus free organic indexing |
| Where candidates apply | Usually on the board itself | Usually redirected to the original source |
| Examples | LinkedIn Jobs, niche and industry boards | Google for Jobs, and search-engine-style job products |
| Best for | Targeted reach on a specific audience; employer-branded listings | Broad distribution and visibility across many sources at once |
How Do the Big Platforms Actually Work?
The lines blur in practice, because several well-known platforms operate as hybrids.
Is Indeed a job board or an aggregator?
Both. Indeed began as a job search engine that aggregated listings from across the web, and it still indexes jobs from many sources. Over time it also added the ability for employers to post openings directly and to sponsor listings, which is job-board behavior. In everyday use it functions as a hybrid: an aggregator with a built-in board.
Is Google for Jobs an aggregator?
Effectively, yes. Google for Jobs is an enhanced search feature inside Google Search, not a standalone board. It surfaces job listings pulled from across the web, including job boards and company career sites, and organizes them into a dedicated experience. Employers do not post to it directly; instead, Google reads structured data (the schema.org JobPosting markup) on a page to understand and display the listing. Candidates are sent to the source site to apply.
Where do LinkedIn and other networks fit?
LinkedIn Jobs behaves primarily as a job board layered on a professional network: employers post openings directly, and candidates apply within the platform. Some networks and tools also distribute a single posting to a wider set of partner sites, which is why one job can appear in many places at once.
Which One Should You Use?
For most employers, this is not an either-or decision. Job boards give you targeted, brand-controlled placement in front of a specific audience. Aggregators give you scale and discoverability across the whole market. Used together, they cover both intent-driven candidates and passive browsers.
The harder problem is managing both at once: different pricing models, different data, and different performance across dozens of destinations. That is where a programmatic job advertising platform helps. Rather than posting and monitoring each source by hand, you can distribute a single set of jobs across boards, aggregators, and search, social, and display channels, then shift budget automatically toward whatever is delivering the best applicants at the best cost.
Frequently Asked Questions
What is the main difference between a job board and a job aggregator?
A job board hosts listings that employers post directly on the site. A job aggregator does not host listings; it collects and indexes jobs from other sites into one searchable place and usually sends candidates to the source to apply.
Is Indeed a job board or a job aggregator?
Indeed operates as both. It started as an aggregator that indexed jobs from across the web and later added direct employer posting and sponsored listings, making it a hybrid.
Is Google for Jobs an aggregator?
Google for Jobs works like an aggregator. It is a search feature within Google that surfaces listings from across the web using structured data on the source pages, and it redirects candidates to those sources to apply rather than hosting the jobs itself.
Do job aggregators charge to list jobs?
Many aggregators index listings organically at no cost, then offer paid options such as cost-per-click or cost-per-applicant to give jobs more visibility. Pricing varies by platform.
Can one job appear on both a job board and an aggregator?
Yes. A job posted on a board can be crawled or fed to aggregators, so the same opening often appears in multiple places. This is common and usually desirable for reach.
Should employers use job boards or aggregators?
Most employers benefit from using both, because boards offer targeted, brand-controlled reach and aggregators offer broad discoverability. Distributing and optimizing across both, ideally through a single platform, tends to produce the best results.
