Job Aggregator

How a job aggregator works

Aggregators gather jobs in three main ways. They crawl employer career sites and read job posting structured data. They take XML feeds from applicant tracking systems, job boards and staffing firms. And they accept jobs posted directly by employers.

They then remove duplicates, classify jobs by title, location and category, and rank them in search results for job seekers. Ranking depends on relevance, freshness, location and, for sponsored jobs, how much the employer is paying.

When a job seeker clicks a job, they are either sent to the employer's own application page or asked to apply within the aggregator, using a profile or resume they have stored there. Which happens depends on the aggregator and the employer's settings, and it has a big effect on conversion.

Job board vs job aggregator

A job board is a site where employers post jobs directly, usually paying per posting or through a subscription. Jobs exist on the board because an employer put them there.

A job aggregator collects jobs from everywhere, including from job boards, and acts like a search engine for jobs. Many large job sites now do both: they accept direct postings and also aggregate listings from elsewhere.

For employers the practical differences are:

• Coverage. Aggregators may list your jobs whether or not you posted them, which means duplicates or stale listings can appear.
• Pricing. Job boards mostly charge per post or slot. Aggregators mostly charge per click or per application for sponsored listings, with free organic listings.
• Control. On a job board you control the ad. On an aggregator, how your job appears depends on your feed and structured data.

Paying for visibility

Most aggregators sell sponsored placement on a cost-per-click (CPC) or cost-per-application (CPA) basis. Typical CPCs for hourly roles are often well under a dollar to a few dollars, and higher for specialist and professional roles, but prices change with competition by role and location.

Worked example: a logistics company sponsors 20 warehouse jobs at an average of $0.60 per click and gets 5,000 clicks a month, a spend of $3,000. If 15% of clickers complete an application, that is 750 applicants, or $4 per applicant. If application completion is only 5% because the apply flow is long, the same spend produces 250 applicants at $12 each. The aggregator did not change; the career site did.

At scale, many employers use programmatic job advertising to set budgets and bids automatically across aggregators and boards, moving spend toward jobs that need applicants and away from those already full.

Getting your jobs seen

• Use clean job posting structured data on every job page: title, location, pay, employment type, date posted and valid-through date.
• Write standard titles. "Warehouse Associate" ranks; "Fulfillment Hero" does not. Put internal titles in the body.
• Include pay. Many aggregators show or filter by pay, and jobs without pay get fewer clicks. Several states and cities also require it in a job posting.
• Keep listings fresh. Close filled jobs promptly and avoid reposting the same job repeatedly to appear new, which some aggregators penalize.
• One job per location. A single listing for "multiple locations" ranks poorly for local searches.
• Fix the apply flow. Clicks you pay for are wasted if the application is long or broken on mobile.

Common mistakes

• Paying for clicks without tracking hires. Measure cost per applicant and cost per hire by source, not clicks alone.
• Sponsoring every job. Most budgets should go to hard-to-fill or urgent roles; easy roles often fill organically.
• Duplicate listings. The same job from your career site, a staffing partner and an old feed confuses candidates and splits applicants.
• Forgetting compliance. Pay transparency, EEO statements and accurate job details apply wherever the job appears.
