The Problem With Most Job Ads
Here is an uncomfortable truth. The best candidates in your market are not reading your job ads. They glance at the title, scan the first two lines, and move on. Not because they are not interested in the role, but because your ad looks exactly like every other ad on the board.
Most job ads fail because they are written for the hiring manager, not the candidate. They lead with what the company wants instead of what the candidate gets. They list 20 requirements when 8 would do. They hide the salary. They use corporate language that nobody actually speaks.
The difference between a job ad that gets 5 applications and one that gets 50 is not the job itself. It is how you present it. This guide shows you exactly how to write job ads that work. If you want to go deeper into structuring job descriptions, we have a separate guide on writing effective job descriptions.
The Anatomy of a High-Performing Job Ad
After analysing thousands of job ads across UK job boards, the ones that consistently attract the most qualified applicants follow a clear structure:
1. A Clear, Searchable Job Title
Your job title is the first thing candidates see, and it determines whether your ad appears in search results. Use the title that candidates actually type into job boards. "Senior Software Engineer" works. "Digital Transformation Ninja" does not.
Avoid internal job codes, creative titles, and unnecessary qualifiers. If the role is a Marketing Manager, call it a Marketing Manager. Add location if it is relevant ("Marketing Manager - Manchester" or "Marketing Manager - Remote UK"). Keep it under 80 characters.
2. The Salary (Yes, Include It)
Job ads that include a salary or salary range get significantly more applications. Research from multiple UK job boards shows that ads with visible salaries receive up to 30% more clicks than those marked "competitive" or "DOE".
Think about it from the candidate's perspective. They have limited time. They are scanning dozens of ads. If two ads look similar but one shows the salary and the other does not, which one gets the click?
If you genuinely cannot disclose the exact number, give a range. "55,000 to 65,000 pounds" is infinitely more useful than "competitive salary". And be honest about the range. Advertising 50,000 to 80,000 when the budget is actually 55,000 erodes trust.
3. An Opening That Speaks to the Candidate
The first two sentences of your ad are make-or-break. Most ads open with a paragraph about the company. "We are a leading provider of..." Nobody cares. Not at this stage, anyway.
Instead, open with something that speaks to what the candidate wants. What will they achieve in this role? What problem will they solve? Why is this role exciting?
Bad: "We are a fast-growing SaaS company looking for a talented Project Manager to join our team."
Good: "You will lead the delivery of three major platform launches this year, working directly with the CTO and a team of 12 engineers. If you want to ship products that matter, not sit in meetings about meetings, keep reading."
The second version tells the candidate what they will actually do, signals the pace and culture, and gives them a reason to keep reading.
4. Requirements (Keep Them Honest)
This is where most job ads go wrong. They list every skill the hiring manager can think of, creating a wish list that no single candidate could ever match. Research shows that men apply when they meet about 60% of the criteria, while women apply when they meet 100%. An inflated requirements list directly reduces your talent pool, especially among underrepresented groups.
Split your requirements into two sections:
- Must-haves (5 to 7 items): The non-negotiable skills and experience. If a candidate does not have these, they genuinely cannot do the job.
- Nice-to-haves (3 to 5 items): Skills that would give a candidate an edge but are not essential. Be honest. If you would still interview someone without this skill, it is a nice-to-have.

Do not just list the standard benefits everyone offers. "25 days holiday plus bank holidays" and "company pension" are expected, not differentiators.
Focus on the benefits that genuinely set this role apart:
- Flexible or remote working arrangements and what they actually look like in practice
- Progression opportunities with specific timelines
- Training budget with the actual amount
- Team culture details that are specific and real, not generic
- Projects they will work on or products they will build
6. A Simple Application Process
Every additional step in your application process costs you candidates. The best talent has options. If your application requires a cover letter, a personality test, a video introduction, and three references before they even speak to someone, you will lose the best applicants to competitors with simpler processes.
For most roles, a CV and a short screening call is enough to make a first-stage decision. Save the assessments for later in the process when the candidate is invested.
Job Ad Mistakes That Kill Your Response Rate
Avoid these common errors that recruiters make every day:
| Mistake | Why It Hurts | What to Do Instead |
|---|---|---|
| Hiding the salary | Candidates skip ads without salary info | Always include a range |
| 20+ requirements | Discourages qualified candidates | Limit to 5-7 must-haves |
| Corporate jargon | Feels impersonal and generic | Write like a human |
| No location clarity | Remote? Hybrid? Office? Candidates need to know | State working arrangement upfront |
| 1,500+ words | Nobody reads it all | Keep it between 300-700 words |
| Copy-pasting the JD | Job descriptions are internal documents, not ads | Write the ad separately, for the candidate |
Using AI to Write Better Job Ads
AI tools like ChatGPT and Claude can dramatically speed up your job ad writing. A well-crafted prompt can generate a solid first draft in under a minute. Here is a practical approach:
Step 1: Gather Your Inputs
Before you open an AI tool, gather the key details: job title, salary range, location and working arrangement, the three most important responsibilities, must-have skills, the biggest selling points of the role, and who the role reports to.
Step 2: Write a Specific Prompt
Generic prompts produce generic ads. Be specific. For example: "Write a job ad for a Senior DevOps Engineer in Manchester. Salary 65,000 to 75,000 pounds. Hybrid working (3 days office, 2 remote). The company is a fintech scaleup with 120 people. The role involves leading cloud infrastructure migration from AWS to GCP. Must-haves: 5+ years DevOps, Kubernetes, Terraform, CI/CD. Tone should be confident and direct, not corporate."

Step 3: Edit and Personalise
Never post an AI-generated ad without editing it. Add specific details only you know (like team dynamics, recent wins, or culture specifics). Remove anything that feels generic. Verify all facts. The AI provides speed and structure. You provide accuracy and personality.
Job Ad SEO: Getting Found on Job Boards
Writing a great ad is pointless if nobody sees it. Here is how to optimise for job board search algorithms:
- Use the exact job title candidates search for. Check Indeed or LinkedIn to see what titles have the most active searches in your sector.
- Include the location in the title. "Account Manager - Birmingham" ranks for location-specific searches.
- Use relevant keywords naturally. Include skills, tools, and qualifications in the body text. Do not keyword-stuff, but make sure the terms candidates search for appear in your ad.
- Post at the right time. Data from UK job boards shows that ads posted on Monday to Wednesday mornings get the most initial engagement.
- Refresh regularly. Most job boards rank newer ads higher. If your ad is not performing after a week, refresh it with an updated title or opening line.
Measuring Your Job Ad Performance
Track these metrics for every ad you post:
- Views to applications ratio. If 500 people view your ad but only 5 apply, the ad itself is the problem.
- Quality of applicants. Are the right people applying, or are you attracting unqualified candidates?
- Time to first quality application. A good ad should generate strong applications within the first 48 hours.
- Source performance. Which job boards are delivering the best candidates for this role type?
Most CRMs and ATS platforms can track these numbers for you. If you are still setting up your tech stack, our CRM comparison guide covers the options available to UK recruiters.
Frequently Asked Questions
How long should a job ad be?
The ideal job ad length is between 300 and 700 words. Research consistently shows that ads in this range receive the most applications. Shorter ads lack enough detail for candidates to self-qualify. Longer ads overwhelm readers and cause drop-off. Focus on the information that genuinely helps a candidate decide whether to apply.
Should I include the salary in a job ad?
Yes. Job ads that include a salary or salary range receive significantly more applications than those that say "competitive" or "dependent on experience". Candidates want to know if a role is worth their time before applying. If you cannot disclose the exact salary, give a realistic range. Hiding the salary is one of the biggest reasons good candidates skip your ad.
How can I make my job ad stand out on job boards?
Start with a clear, specific job title that candidates actually search for. Include the salary upfront. Open with a compelling hook that speaks to the candidate's goals, not just your company's needs. Use bullet points for requirements and benefits. Keep the tone conversational and avoid corporate jargon. A well-structured, honest ad naturally stands out because most job ads are poorly written.
Can AI help me write better job ads?
Yes. AI tools like ChatGPT and Claude can generate strong first drafts of job ads in seconds. The key is writing a good prompt that includes the role details, target audience, company culture, and the tone you want. AI handles the structure and persuasion while you add the accuracy and market knowledge. Many recruiters report saving 30 to 60 minutes per job ad using AI. The Pro Playbook for Recruiters includes a library of tested prompts specifically for this purpose.
