The Problem with Most Job Ads
Here is an uncomfortable truth. The majority of job ads posted on UK job boards are terrible. They read like legal documents. They are stuffed with jargon. They list 25 requirements and offer nothing in return except "competitive salary" and "great team."
The result? The best candidates scroll straight past. The people who do apply are often underqualified or desperate. And the recruiter or hiring manager wonders why they cannot fill the role.
Writing a good job ad is not complicated. But it does require you to think like a marketer, not a bureaucrat. Your job ad is an advert. It needs to sell the opportunity to the people you want to attract, while giving them enough information to self-select in or out.
This guide covers the specific techniques, frameworks, and examples that consistently produce better results. Whether you are a recruiter posting 50 ads a month or a hiring manager who writes one a year, these principles will make a measurable difference.
The Anatomy of a High-Performing Job Ad
A well-structured job ad follows a clear pattern. Every section has a specific purpose, and the order matters because it mirrors how candidates actually read and make decisions.
1. The Job Title
Your title is the single most important element. It determines whether anyone clicks on your ad in the first place. Keep it simple, specific, and searchable.
Good examples:
- Senior Software Engineer - Python (Remote, UK)
- Marketing Manager - B2B SaaS, Manchester
- Qualified Electrician - Domestic, South London
Bad examples:
- Rockstar Developer Wanted!
- Amazing Opportunity in Marketing
- Spark Your Career (this was a real ad for an electrician)
The title should include the job title that candidates actually search for, the seniority level, and ideally the location or remote status. Drop the creativity here. Candidates search for "Software Engineer" not "Code Ninja."
2. The Opening Hook (First 2-3 Sentences)
Most candidates decide within the first few seconds whether to keep reading. Your opening needs to grab attention immediately. Do not start with a company history lesson. Start with what makes this role genuinely interesting.
"We are building the platform that 200,000 UK small businesses use to manage their finances. Our engineering team is 12 people, growing to 20 this year, and we need senior engineers who want to own entire product areas, not just write tickets."
Compare that to: "Founded in 2015, we are an award-winning fintech company based in London with a passion for innovation..." Nobody finishes reading that sentence.
3. What the Candidate Gets
Before you list what you need from candidates, tell them what they get. This is where most job ads fail completely. They jump straight into requirements without selling the opportunity.
Cover these points:
- Salary or salary range. This is the single biggest driver of application rates. Always include it.
- Benefits that actually matter. Not "competitive benefits package." Specific things like "33 days holiday," "4-day week," "fully remote," or "12% pension contribution."
- Career growth. Where does this role lead? What will they learn? Who will they work with?
- The work itself. What will they actually spend their days doing? Make it sound interesting because if it is not interesting, why would anyone apply?
4. Requirements (Keep Them Honest)
This is where most ads go wrong. They list 15 to 20 requirements when the role genuinely needs five or six. Every unnecessary requirement you add filters out good candidates, especially women and underrepresented groups who are more likely to self-select out if they do not meet every single criterion.
Split your requirements into two categories:
- Must-haves (3-5 items). The genuine non-negotiables. If someone does not have these, they cannot do the job.
- Nice-to-haves (2-3 items). Things that would be a bonus but are not deal-breakers.
Be honest about which is which. If you would interview someone without a degree in the right subject, do not list it as a must-have.

Keep the company section short. Two to three sentences maximum. Candidates will research you online anyway. Focus on the things that are genuinely different about working there, not generic statements about being "innovative" or "passionate."
6. The Application Process
Tell candidates exactly what happens next. How many interview stages? What format? When will they hear back? Transparency here reduces drop-off and shows respect for candidates' time.
The AIDA Framework for Job Ads
If you want a simple framework to follow, use AIDA. It is borrowed from marketing copywriting and works perfectly for job ads.
- Attention: A clear, searchable job title and a strong opening hook.
- Interest: What makes this role genuinely compelling? The project, the team, the growth opportunity.
- Desire: The salary, benefits, and working conditions that make candidates want this specific role.
- Action: A clear call to apply with information about the process.
Common Mistakes That Kill Application Rates
Based on data from thousands of UK job ads, these are the most common mistakes that reduce application rates.
Not Including Salary
This is the number one issue. Job ads with salary information get up to 30% more applications than those without. "Competitive salary" is not a salary. Neither is "DOE" (depending on experience). Candidates assume you are hiding the salary because it is below market rate. Even a range like "45,000 to 55,000 pounds depending on experience" is far better than nothing.
Too Many Requirements
Every additional requirement you add reduces your applicant pool. A study by LinkedIn found that women apply for roles when they meet 100% of the requirements, while men apply when they meet 60%. If you list 15 requirements, you are filtering out a huge proportion of qualified candidates. Stick to five or six genuine must-haves.
Writing for the Company, Not the Candidate
Your ad should be structured around what the candidate wants to know, not what the company wants to say. Candidates care about what they will do, what they will earn, and how they will grow. Lead with those answers.
Using Jargon and Buzzwords
"Dynamic," "passionate," "fast-paced," "disruptive." These words have lost all meaning. They tell the candidate nothing specific about the role. Replace them with concrete details. Instead of "fast-paced environment," say "we ship features every two weeks and you will be making decisions daily."
Forgetting SEO
Job boards are search engines. If your job title does not match what candidates actually search for, your ad will not appear in results. Use standard job titles, include the location, and use relevant keywords naturally throughout the ad.
Using AI to Write Better Job Ads
AI tools like ChatGPT and Claude can dramatically speed up the job ad writing process. They are particularly good at taking a dry job description and transforming it into a compelling advert.
The key is giving the AI enough context. Here is a simple prompt framework:
"Write a job advert for [role title] at [company name]. Target audience is [describe ideal candidate]. Key selling points are [salary, benefits, culture]. Must-have skills are [list 4-5]. The tone should be professional but conversational. Include salary of [amount]. Keep it under 600 words."

Job Ad Performance Benchmarks
How do you know if your job ads are performing well? Here are some UK benchmarks to measure against.
| Metric | Average | Good | Excellent |
|---|---|---|---|
| Click-through rate (job board) | 1-2% | 3-5% | 5%+ |
| Apply rate (views to applications) | 5-8% | 10-15% | 15%+ |
| Qualified applicant ratio | 10-20% | 25-40% | 40%+ |
| Time to first quality application | 3-5 days | 1-2 days | Same day |
Track these metrics for every ad you post. Over time, you will see patterns in what works and what does not for your specific market and roles. Use your recruitment KPIs alongside these ad metrics for a complete picture of your performance.
Frequently Asked Questions
How long should a job ad be?
The ideal job ad is 400 to 700 words. Research from job boards like Indeed and Reed shows that ads in this range consistently get the highest application rates. Shorter ads lack enough detail for candidates to self-qualify. Longer ads cause drop-off. Front-load the most important information and keep the requirements list focused on genuine must-haves.
Should I include salary in a job ad?
Yes, always include salary or at least a salary range. Job ads with salary information receive significantly more applications than those without. Candidates increasingly skip ads that say "competitive salary" because they assume it means the pay is below market rate. If you genuinely cannot disclose exact figures, provide a range like 45,000 to 55,000 pounds.
What is the biggest mistake in job advertising?
The biggest mistake is writing the ad from the employer's perspective rather than the candidate's. Most job ads are just lists of demands. The best job ads flip this by leading with what the candidate gets: the opportunity, the culture, the career growth, and the compensation. Sell the role first, then outline the requirements.
Can AI help me write better job ads?
Yes, AI tools like ChatGPT and Claude are excellent for writing job ads. They can take a bland job description and transform it into a compelling advert in seconds. The key is giving the AI enough context: the role details, target candidate profile, company selling points, and the tone you want. Always review and edit the output before publishing.
