A small business owner working on how to write a job description at her desk

Hiring the wrong person is one of the most expensive mistakes a small business can make, and it often starts with a weak job description. A vague, copy-pasted, or wildly unrealistic job ad attracts a flood of poorly matched applicants, or worse, scares off the capable, steady people you actually want. A good one does the opposite: it draws in the right people and gently filters out the rest, before you have spent a single hour interviewing.

This guide explains how to write a job description that attracts the right people: the difference between a job description and a job ad, what to include, how to make it genuinely appealing, and the common mistakes that quietly cost you good candidates. Get this right and the whole rest of your hiring becomes easier.

Why a Good Job Description Matters

Your job description does a lot of quiet work before anyone applies. It is the first impression of your business for every candidate, it sets the expectations the role will be judged against, and it decides who takes the time to apply. Written well, it is a filter that saves you from a pile of wrong-fit applications. Written badly, it either repels good people or buries you in unsuitable ones.

47%
job ads that show a salary attract an average of 47% more applications, and most jobseekers say they are more likely to apply when a pay range is listed, according to SEEK research, a simple example of how a detail in your ad changes who applies (SEEK).

Small choices like that add up to the difference between a hire you are thrilled with and one you regret. Getting the job description right is the foundation of good hiring, and it feeds everything that follows, from your interviews to your onboarding and performance conversations. It is a core part of building a strong team and a healthy leadership and culture.

Job Description vs Job Ad

It helps to be clear on two related documents that people often confuse. A job description is the internal document that defines the role: its purpose, its key responsibilities, the skills and experience needed, who it reports to, and how success will be measured. It is your foundation, used for hiring and then for managing the person once they start.

A job ad is the public version you post to attract applicants. It draws on the job description but is written to appeal: it leads with why the role matters, shows what you offer, reflects your culture, and invites the right people to apply. For a small business the two overlap a great deal, so the practical approach is to write a clear job description first, then shape it into an appealing ad. Nail the description, and the ad almost writes itself.

The Sections Every Job Description Needs

A good job description is not long, but it does cover the essentials in a clear order. Here are the sections to include, and what belongs in each.

A clear job description is the foundation for everything that follows, from attracting the right applicants to running focused interviews and setting fair expectations.
SectionWhat to include
Job title A clear, searchable title people actually look for, not a quirky internal one
Role summary A short paragraph on the purpose of the role and why it matters to the business
Key responsibilities The 5 to 8 things they will actually spend their time on, not an exhaustive list
Skills and experience What is genuinely required, kept separate from what is merely nice to have
The practical details Location, hours, employment type, who they report to, and the salary range
What you offer Pay, culture, benefits and a genuine sense of what it is like to work with you
How to apply Clear instructions and, ideally, a real person as a point of contact

Cover these and nothing important is left to guesswork. If you are hiring for the first time, this same structure pairs with our step-by-step guide to hiring your first employee, which walks through the legal and practical side of bringing someone on.

Including the right sections makes a job description complete. Making it attract the right people takes a little more craft. The aim is not the biggest possible pile of applications; it is the right handful of people who understand the role, want it, and fit how you work.

Writing to Attract the Right Person

  • Write to one person. Picture your ideal candidate and speak directly to them, rather than to a vague, faceless crowd.
  • Lead with why it matters. Open with the purpose and impact of the role, not a dry list of duties, so good people lean in.
  • Be honest about the role. Describe the real day-to-day, including the hard or repetitive parts, so people can self-select accurately.
  • Name your values. Say what you stand for and what it is like to work with you, so the right people are drawn in and the wrong ones step away.
  • Include the salary. Show a pay range, because it attracts more and better-matched applicants and signals respect and transparency.
  • Keep the must-haves short. Separate genuine requirements from nice-to-haves, so you do not scare off capable people who tick most boxes.
  • Use plain, welcoming language. Drop the jargon and clichés, and avoid anything that could unintentionally exclude good people.

The real payoff of a well-written job description is a team of the right people: those who understand the role, want it, and genuinely fit how you work.

Done this way, your job description becomes a quiet matchmaker, drawing in the people who belong and gently waving off the ones who do not. That clarity also sets the tone for the kind of culture that keeps good people once they join, which connects to everything we cover on reducing staff turnover.

Common Mistakes to Avoid

A few predictable mistakes undo an otherwise good job description. The biggest is the endless requirements list: a wish list of twenty must-have skills that no real person possesses, which scares off strong candidates who would have thrived. Close behind is the vague buzzword soup of rockstars, ninjas and fast-paced environments, which describes nothing and often repels the steady, capable people you actually want.

Other common traps include hiding the salary, which cuts your applications and your fit; copy-pasting a generic template that could describe any business and inspires no one; and describing an impossible, do-everything role that really should be two jobs. Watch out too for language that could discriminate or unintentionally exclude, such as young and energetic, which can breach anti-discrimination expectations and narrow your pool; your obligations here sit alongside the basics of Fair Work compliance. Avoid these, write with honesty and clarity, and your job description will do its job: attracting the right people and quietly filtering out the rest.

Seek Out the Right People

Choosing the right people to bring into your business is one of the most consequential things you do, and Scripture takes it seriously. When the early church needed to appoint people to a practical role, the apostles did not grab whoever was available. They set clear criteria for the kind of person they were looking for.

"Therefore, brethren, seek out from among you seven men of good reputation, full of the Holy Spirit and wisdom, whom we may appoint over this business."

Acts 6:3 (NKJV)

Notice the care in it: a clear number, a clear character (good reputation, wisdom), and a clear purpose (appointed over this business). A well-written job description is exactly this discipline applied to your hiring: deciding in advance the character and capability you are seeking, rather than settling for whoever turns up. Scripture also honours skill and excellence in a person's work.

"Do you see a man who excels in his work? He will stand before kings; He will not stand before unknown men."

Proverbs 22:29 (NKJV)

Seeking out people of good character who excel in their work, and describing clearly the role you are calling them to, is wise and faithful stewardship of your business and of the people who will give it their time and talent. As a Christian business coach, helping owners hire with that kind of clarity and care, and build teams that thrive, is exactly the sort of practical wisdom we love to bring alongside you.

Frequently Asked Questions

What is the difference between a job description and a job ad?
A job description is the internal document that defines a role: its purpose, responsibilities, the skills needed, who it reports to, and how success is measured. It is the foundation you use for hiring, setting expectations and later managing performance. A job ad is the public, outward-facing version you post to attract applicants. It draws on the job description but is written to sell the role: it leads with why the job matters, shows what you offer, reflects your culture, and invites the right people to apply. For a small business the two overlap heavily, so it is common to write a solid job description first, then turn it into an appealing job ad. Getting the description right makes the ad far easier and sharper.
Should I include a salary range in the job ad?
In almost all cases, yes. Research from SEEK shows that including a salary in a job ad leads to significantly more applications, and a large share of jobseekers simply will not apply to a role that hides the pay. Listing a salary range also attracts better-matched candidates, because people can quickly see whether the role fits their expectations, which saves you time interviewing people who were never going to accept the pay. It signals transparency and respect, which the right people value. If you are unsure of the exact figure, a sensible range is far better than nothing. Hiding salary to keep options open usually just means fewer and less suitable applicants.
How long should a job description be?
Long enough to be clear, short enough to be read. Most good job descriptions fit comfortably on a page or two. The most common mistake is making it too long, with an exhaustive list of twenty or thirty duties and a wish list of requirements that no single person could meet. That overwhelms good candidates and often scares them off. Aim instead for a focused role summary, five to eight genuine key responsibilities, a short list of the skills that truly matter, and the practical details. If a reader can understand in a couple of minutes what the role is, whether they are a fit, and why they would want it, you have the length about right.
How do I attract the right people and not just more applicants?
By being specific and honest rather than broad and vague. Describe the real day-to-day of the role, including the parts that are hard or repetitive, so people can self-select accurately. Be clear about the few skills that genuinely matter, and separate them from the nice-to-haves, so you do not scare off capable people who tick most boxes. Name your values and what it is actually like to work with you, because the right people are drawn to a clear culture while the wrong ones quietly step away. The goal is not the biggest pile of applications; it is the right handful of people who understand the role, want it, and fit how you work.
What words should I avoid in a job description?
Avoid vague buzzwords and clichés that say nothing, such as rockstar, ninja, guru, and fast-paced, as well as tired phrases like work hard play hard. They do not describe the job and can put off exactly the steady, capable people you want. Be careful too with language that could discriminate or unintentionally exclude, such as young and energetic, which can breach anti-discrimination expectations and narrow your pool. Drop internal jargon and acronyms a candidate would not know. Instead, use plain, specific, welcoming language that describes the real work and the kind of person who would do it well. Clear beats clever every time, and it reaches a wider, better-matched group of people.
