Writing Effective Job Adverts

Essential Elements

• Not overly creative (people search standard terms)
• Accurate reflection of level

2. Company information

• Company name (unless genuine confidentiality needed)
• Brief description of what you do
• Location(s)
• Company size (gives context)

3. Role summary

• What the job involves (2-3 sentences)
• Who they'll work with
• Purpose of the role

4. Key responsibilities

• 5-8 main duties
• Use bullet points
• Action verbs (manage, develop, lead, analyze)
• Be specific, not generic

5. Essential requirements

• Skills absolutely needed from day one
• Qualifications if genuinely necessary
• Experience level required
• Any mandatory requirements (license, registration)

6. Desirable criteria

• Nice-to-have skills
• Preferred experience
• Don't overload this section

7. Salary and benefits

• State salary or range
• Mention key benefits (pension, holidays, flexibility)
• Highlight anything that makes you stand out

8. Working arrangements

• Hours per week
• Full-time/part-time/flexible
• Office-based/remote/hybrid
• Shift patterns if applicable

9. How to apply

• Clear instructions
• Application deadline
• Expected interview dates
• Contact for questions

10. Equal opportunities statement

• Reassures candidates you're professional

Writing Style

Do:

• Be clear and concise
• Use plain English
• Be honest about the role
• Highlight what makes you a good employer
• Show your culture and values
• Make it easy to skim-read
• Proofread carefully (errors suggest unprofessional)

Don't:

• Use jargon or acronyms (unless industry-standard)
• Make it too long (people skim)
• Oversell or exaggerate
• Be vague ("various duties")
• Copy-paste generic descriptions
• Use discriminatory language

Salary: To State or Not?

Arguments for stating salary:

• Attracts candidates in your budget
• Reduces time-wasters
• Shows transparency and fairness
• Increasingly expected by candidates
• Required in some sectors (public sector often must)

Arguments against:

• Negotiation flexibility
• Current employees may see it
• Competitors see what you pay
• May limit applicant pool if lower than market

Best practice: State a range (e.g., "£35,000-£40,000 depending on experience")

Minimum: Don't say "competitive" with no figure - state at least "from £X"

Legal Requirements

What You MUST Do

1. Don't discriminate

Your advert must not discriminate based on:

• Age
• Disability
• Gender reassignment
• Marriage/civil partnership
• Pregnancy/maternity
• Race
• Religion or belief
• Sex
• Sexual orientation

2. Comply with National Minimum Wage Act

If you mention salary, it must be realistic. Don't advertise minimum wage roles as "excellent salary" or "competitive pay" without stating actual amount.

3. Be truthful

Don't misrepresent:

• The role or seniority
• Working conditions
• Salary or benefits
• Company situation

Misrepresentation can lead to breach of contract claims or candidates withdrawing.

4. GDPR compliance

If collecting applications, you need:

• Privacy notice explaining data use
• Lawful basis (usually legitimate interests for recruitment)
• Secure storage
• Data retention policy

Discriminatory Language to Avoid

Age discrimination: ❌ "Recent graduate" ❌ "Young, dynamic team" ❌ "Digital native" ❌ "Experienced" (could imply older) ❌ "Energetic" ✅ "2+ years' experience" (specific, not age-proxy)

Gender discrimination: ❌ "Salesman" (use salesperson) ❌ "Waitress" (use server/waiting staff) ❌ "Handyman" (use maintenance worker) ❌ "Cleaning lady" (use cleaner)

Race/nationality discrimination: ❌ "Native English speaker" ❌ "British or EU passport" (unless genuine requirement post-Brexit) ❌ "No foreign accent" ✅ "Fluent in English" (if genuinely needed)

Disability discrimination: ❌ "Physically fit" ❌ "Able-bodied" ❌ "Must be able to stand for 8 hours" (unless genuinely necessary) ✅ State actual requirements: "Role involves frequent stair climbing"

Marital/family status: ❌ "Single" ❌ "No family commitments" ❌ "Must be flexible with hours" (implies childcare issues)

Other: ❌ "Recent school leaver" (age) ❌ "Mature person" (age) ❌ "Attractive" (sex/appearance)

When You CAN Specify Characteristics

Genuine Occupational Requirement (GOR):

Very rare, but you can specify protected characteristics if:

• Authenticity needed (actor to play specific role)
• Privacy/decency (changing room attendant same sex)
• Religion (minister of religion)
• Organized religion roles (Catholic school may prefer Catholic)

Must be:

• Proportionate
• Necessary for the role
• Applied narrowly

Get legal advice before using GOR.

Standing Out in a Competitive Market

Show Your Culture

What makes you different?

• Flexible working from day one
• Career development opportunities
• Modern, collaborative environment
• Strong values and purpose
• Supportive team culture
• Work-life balance commitment

Show, don't tell: ❌ "We're a fun, fast-paced environment" ✅ "We offer flexible hours, weekly team lunches, and monthly learning budgets"

Highlight Benefits

Beyond salary, emphasize:

• Enhanced pension
• Private healthcare
• More holiday than statutory
• Hybrid/remote working
• Training and development
• Performance bonuses
• Death in service
• Employee assistance programme
• Gym membership
• Cycle to work scheme

Use Real Employee Quotes

"I joined as a junior and was promoted twice in 18 months" - Sarah, Operations Manager

Real testimonials add credibility.

Include Application Stats

"80% of our managers were promoted internally" "Average tenure: 5 years"

Shows it's a good place to work.

Common Mistakes

Being too demanding:

• Requiring master's degree for admin role
• "5 years' experience in software that's 3 years old"
• Expecting expert in 10 different tools
• Result: No applications

Being too vague:

• "Various duties"
• "Fast-paced environment"
• "Dealing with customers"
• Result: Wrong applicants or no applications

Copying competitors:

• Generic, boring copy
• Same language as everyone else
• Nothing distinctive
• Result: Don't stand out

Ignoring mobile users:

• 60%+ of job seekers use mobile
• Long application forms fail on mobile
• Result: Lose half your applicants

No call to action:

• Unclear how to apply
• Complicated process
• Result: Candidates give up

Slow response:

• Taking weeks to acknowledge applications
• Candidates accept other offers
• Result: Lose best people

Where NOT to Advertise

Avoid:

• Unprofessional platforms
• Sites known for spam
• WhatsApp groups where posting T&Cs unclear
• Your personal social media (mixing personal/professional)
• Anywhere you can't provide privacy notice

Measuring Success

Track:

• Number of applications
• Quality of applications
• Cost per hire (advertising spend / hires made)
• Time to hire
• Source of best candidates (which platform works)
• Diversity of applicant pool
• Offer acceptance rate

Adjust strategy based on data:

• If too many poor applications → make requirements clearer
• If too few applications → advertise wider, improve advert
• If one platform works well → invest more there
• If diverse candidates not applying → review language
