Job Posting:
Definition, Types & Comparison

A job posting is an advertisement for an open employment position that companies publish online, in newspapers, or through other media sources to attract qualified candidates. It includes a description of the job, its responsibilities, required qualifications, and other relevant information designed to encourage applications from potential hires.

Job postings serve as external marketing documents that introduce both the role and the organization to job seekers. They differ from internal job descriptions by focusing on selling the position rather than providing comprehensive documentation. Modern job postings primarily appear on digital platforms such as job boards, social media, and company websites, reaching wider audiences instantly compared to traditional newspaper advertisements.

Job postings fall into 2 categories based on their target audience:

• Internal job postings: Advertised only to current employees within the organization, also called employee referral programs. These allow employers to fill positions quickly and at lower cost per hire compared to external recruitment.
• External job postings: Advertised to the public through online job boards, recruitment websites, and other external channels. These aim to attract qualified candidates from outside the organization's current employee base.

Writing an effective job posting requires attention to both technical details and inclusive language. Start with a clear, industry-standard job title that job seekers will use in searches. Obscure or overly creative titles reduce visibility in job board search results.

Structure your job posting with these 7 components:

1. Clear job title with engaging lead highlighting top perks
2. Brief company introduction describing history, values, and culture
3. Concise job description covering primary responsibilities
4. List of 5 to 6 top benefits and perks
5. Location details including city, state, and remote work options
6. Contact information and clear application instructions
7. Salary range when required by pay transparency regulations

Include salary information and expected compensation ranges to set clear expectations. Use accessible language that avoids jargon, wordiness, and vague soft skills like "attention to detail." Focus on specific, measurable qualifications and quantifiable experience requirements.

Always edit thoroughly before publishing. Typos and mistakes create poor first impressions and can deter qualified candidates from applying.

Job postings automatically include certain standardized information and require specific content based on legal and organizational requirements. At the University of Washington, for example, job postings automatically display pay range minimum and maximum, other compensation, benefits information, shift details, position type (temporary or regular), FTE, union affiliation, and equal opportunity employer statements.

Required elements you must include in the job posting text are:

• Position title and department
• Reporting structure
• Key responsibilities with estimated percent time breakdown totaling 100%
• Minimum qualifications that mirror approved position specifications
• Essential job duties the employee will perform
• Supervisory responsibilities if applicable

Optional but recommended elements include additional qualifications, preferred qualifications (3 to 5 nice-to-have skills), working conditions, application requirements (cover letter, portfolio), and information about the team or department.

Job postings reach candidates through 10 popular online platforms:

• Indeed
• LinkedIn
• Glassdoor
• Monster
• ZipRecruiter
• CareerBuilder
• Craigslist
• The Ladders
• Job.com
• Simply Hired

Posting methods vary by platform. On LinkedIn, users navigate to the "For business" tab and select "Post a Job" to enter required details and set posting duration. On Indeed, employers click "Post a Job," enter job details, specify screening questions, and can sponsor postings to increase visibility. Monster requires creating an account, selecting job type (full-time, part-time, contract), entering details, and creating optional screening questionnaires.

Research shows that 80% of applicants to tech jobs come from inbound sources like company career pages, LinkedIn, and online job boards, making these platforms critical for recruitment success.

Internal job postings target current employees within the organization and are typically advertised through internal channels only. Organizations use these to fill positions from their existing workforce, enabling faster hiring timelines and lower recruitment costs compared to external hiring.

External job postings advertise open positions to the general public through job boards, recruitment websites, social media, and company career pages. These postings aim to attract qualified talent from outside the current employee base and typically reach significantly larger candidate pools.

A job posting is often compared to 2 related recruiting concepts:

Job Posting vs. Job Description

A job description is a comprehensive internal document that outlines detailed tasks, duties, functions, and responsibilities of a position in plain language. It serves as a tool for setting employee expectations, measuring performance, and ensuring compliance with company guidelines and employment law. Job descriptions help organizations understand reporting structures, determine compensation, and conduct performance reviews.

A job posting is an external marketing document designed to attract candidates by providing a concise, engaging overview of the position and company. It focuses on selling the role rather than documenting every detail. Job postings are typically shorter, use inclusive language, highlight benefits and perks, and convey company culture. While job descriptions are exhaustive internal documents, job postings are succinct elevator pitches.

Using an internal job description as a job posting creates problems because the two documents serve different purposes. Job descriptions provide comprehensive information for internal use, while job postings must achieve specific recruiting goals: appearing in job board searches, describing the job clearly and succinctly, introducing the company, welcoming applicants with inclusive language, and representing the employer brand. Copying and pasting a job description as a job posting can reduce the size, quality, and diversity of the applicant pool.

Job Posting vs. Job Opening

Job postings represent positions that employers choose to advertise online or through other media. They are voluntary advertisements and only reflect jobs that companies actively promote to attract applicants. This means certain positions may be over-represented by job postings relative to actual availability, while others are under-represented.

Job openings are estimated measures of labor demand that account for actual job growth and estimated replacement needs for workers who retire, change careers, or leave the workforce permanently. The Bureau of Labor Statistics develops replacement rates per occupation to calculate job openings. Job openings take a conservative approach to measuring demand but do not account for workers simply moving out of a region or switching jobs within the same occupation.

Job postings can represent the ceiling of demand for a position in a region when employers actively advertise online. However, true labor demand typically falls somewhere between job postings and job openings. Job postings provide useful detail about desired skills, specific job titles, and hiring companies, but one posting rarely equals one job opportunity.
