How to Write a Job Advertisement That Works (UK Employer Guide)

Writing a job advert sounds simple, but it is one of the most common reasons employers struggle to hire the right people. Many vacancies receive either very few applications or large numbers of unsuitable ones. In most cases, the problem is not the job market — it is the way the advert is written.

Why Most Job Adverts Fail

The majority of job adverts fail because they are written from the employer’s point of view rather than the candidate’s. Employers often focus on internal jargon, long lists of requirements, or vague promises instead of clearly explaining what the job actually involves.

Common reasons job adverts fail include:

• Unclear or misleading job titles
• No salary information
• Overly long or dull descriptions
• Unrealistic expectations
• Corporate language that tells candidates nothing

A good job advert should answer a candidate’s questions quickly and honestly.

Start With a Job Title People Actually Search For

The job title is the most important part of your advert. It determines whether your vacancy appears in search results and whether candidates click on it.

Avoid internal or creative titles that mean little outside your organisation.

Bad job titles:

• Customer Happiness Champion
• Operations Ninja
• Sales Rockstar

Better job titles:

• Customer Service Advisor
• Operations Manager
• Sales Executive

Use plain, widely recognised job titles that reflect what the role actually is.

Open With a Clear, Honest Summary

The first few lines of your job advert should quickly explain:

• What the role is
• Who it would suit
• Where it is based
• Whether it is full-time, part-time, or remote

This section should be short and readable. Candidates often skim adverts, so clarity matters more than clever wording.

Explain the Role — Not Just the Company

Many job adverts include long company introductions but very little about the day-to-day job. Candidates care far more about what they will actually be doing.

Explain the role in practical terms:

• What tasks make up a normal day
• Who the role reports to
• Whether the work is independent or team-based
• What success looks like in the role

Being honest here reduces unsuitable applications and improves retention.

Be Realistic About Requirements

One of the biggest mistakes employers make is listing too many requirements. This can put off good candidates who meet most — but not all — of the criteria.

Separate essentials from nice-to-haves:

• Essential requirements – skills or experience needed to do the job
• Desirable requirements – skills that can be learned after hiring

Long lists of requirements often discourage strong candidates, especially women and career changers.

Salary Transparency Matters More Than Ever

Job adverts without salary information consistently perform worse. Many candidates will not apply at all if the salary is unclear.

If you cannot offer a fixed salary, consider:

• Providing a realistic salary range
• Explaining how pay progresses
• Including key benefits that add value

Phrases like “competitive salary” usually reduce trust and increase drop-off.

Keep the Language Clear and Human

Avoid corporate jargon and clichés. Candidates respond better to clear, direct language.

Instead of:

• “Fast-paced dynamic environment”
• “Self-starter with a can-do attitude”

Try describing what the pace and expectations actually are.

Mention Flexibility Where Possible

Flexible working arrangements can significantly increase the number of quality applications.

This might include:

• Remote or hybrid options
• Flexible start and finish times
• Compressed hours

If flexibility is genuinely not available, it is better to be clear than vague.

Legal and Fair Hiring Considerations

Your job advert must avoid discriminatory language and comply with employment law.

Good practice includes:

• Using inclusive language
• Avoiding age-specific wording
• Not making assumptions about health or personal circumstances

Keeping language neutral helps protect your business and widens your candidate pool.

Where to Place the Call to Action

A strong job advert clearly explains what the candidate should do next.

This may include:

• How to apply
• What documents are required
• The closing date

Clear instructions reduce confusion and incomplete applications.

Review Your Advert Before Publishing

Before posting your vacancy, check:

• Is the job title clear and accurate?
• Is the salary visible or explained?
• Does the advert explain the job clearly?
• Would you apply if you were the candidate?

Better Job Adverts Save Time and Money

A well-written job advert attracts fewer but more suitable candidates, reduces shortlisting time, and improves hiring outcomes. Investing time upfront often saves money later.

Writing clearly, honestly, and with the candidate in mind is one of the most effective recruitment steps an employer can take.
