How do you write a useful job advert?
By describing the job and the conditions honestly, and by removing the barriers that quietly exclude good candidates — most job adverts fail at both, which is why they attract the wrong applicants and repel the right ones.
Include the salary. This is the highest-impact change available. Adverts without a salary attract fewer and worse-matched applicants, waste everyone's time through late-stage mismatches, and entrench pay gaps, because outcomes then depend on who negotiates hardest. Several jurisdictions now require pay ranges by law. "Competitive" tells a candidate nothing except that you would rather not say.
Separate essential from desirable — ruthlessly. Long requirement lists are a documented filter with a bias: research consistently finds that under-represented candidates are more likely to self-select out when they do not meet every criterion, while others apply anyway. Every item you add costs you applicants you would have wanted. If a requirement has never been the reason someone failed, it is not essential.
Describe the actual work. What will this person do in a typical week, what problems will they solve, who will they work with, what does success look like in six months. Candidates cannot assess fit from a list of responsibilities written as verbs.
State the conditions plainly — location and what hybrid actually means in days, hours, shift patterns, travel, the contract type and its duration.
Describe the process — how many stages, what each involves, rough timescale, and who they will meet. This is cheap, rare and disproportionately appreciated.
Write in plain language. Jargon, internal acronyms and inflated titles obscure what the job is. A title nobody searches for will not be found.
What to cut: "rockstar", "ninja" and "family"; unexplained years-of-experience thresholds, which are weak proxies and can be age-discriminatory; boilerplate about being dynamic and fast-paced; and degree requirements for roles that do not need one, which exclude capable applicants for no measured benefit.
Say how to ask questions, and name a real person.
