Job advertising: how to write, place and budget job ads that get applicants

Job advertising is paying to put an open role in front of the people you want to hire. A job posting is the description of the role; a job ad is the paid placement that gets it seen, on job boards, on LinkedIn, on social media or through programmatic platforms that spread your budget across many sites. Good job advertising is about two things: writing an ad the right person wants to click, and showing it where that person actually spends time.

This guide covers the main channels and how they charge, how to write ads that convert, how to set a budget, and what to do when the people you need are not looking at job boards at all.

Job posting vs job advertising

The two are often mixed up. A job posting is free or close to free: you publish the role on your careers page and on job boards that accept organic listings. Job advertising starts when you pay for reach, by sponsoring the listing, promoting it or running ads on platforms where people are not searching for jobs. Most hiring teams need both. The posting holds the information; the advertising brings people to it.

The main job advertising channels

None of the big platforms publishes a fixed price list for sponsored jobs. Prices are set in an auction and vary by job title, location and competition, so treat any cost-per-click figure you read online as a rough guide and check the current terms in each platform before you budget.

Facebook job ads: what is different

Facebook and Instagram reach people who are not looking for a job, which is exactly why they work for roles where job boards come up empty. Employment ads are a special ad category in Meta's system. For ads that run in the United States, Canada and parts of Europe, Meta restricts targeting: you cannot narrow by age or gender, postcode targeting is not available, location targeting uses a minimum radius and lookalike audiences are limited. That is good for fairness, but it means the ad itself has to do the filtering. Name the role, the place and the key requirement in the first line, and ask a short qualifying question in the application.

Programmatic job advertising

Programmatic job advertising uses software to buy and place job ads automatically across many job boards and sites. You set a goal, such as a target cost per application, a daily budget and locations, and the platform shifts spend towards the sites that deliver. Appcast, Joveo and PandoLogic are among the best-known vendors.

• It suits employers with many open roles across locations, where manual budget allocation is impossible
• It needs good tracking: the platform can only optimise towards applications or hires it can see
• It still only reaches people browsing job sites. It does not solve a shortage of active candidates

How to write a job ad that gets applicants

• Use the title candidates search for. «Warehouse operative» beats «Fulfilment associate»
• Put pay, location and hours in the first lines. They are what candidates decide on
• Write to one person, in the second person. «You will» reads better than «the successful candidate will»
• Separate must-haves from nice-to-haves. Every extra requirement filters out good people who think they do not qualify
• Show a real day in the job, with real photos or a short video of real colleagues
• Make applying fast on a phone. For frontline roles, a CV upload as step one loses many of the people you want
• For social ads, write a short hook and send people to a short application page, not the full job description

How much should you spend on job advertising

Start from the cost of an unfilled role, not from last year's budget. If a vacancy costs you lost revenue, overtime or agency fees every week it stays open, a modest ad budget that fills it two weeks faster usually pays for itself. Then track three numbers per channel: cost per application, cost per qualified candidate and cost per hire. Cost per application on its own is misleading, because cheap clicks often bring applicants who do not meet the requirements.

• Begin with a small test budget per channel and role for one to two weeks
• Compare cost per qualified candidate, not cost per click
• Move budget to the channel that produces hires, and cut the rest
• Refresh creative when results drop. Social ads tire faster than job board listings

How to get more applicants

When applications dry up, most teams rewrite the ad or raise the budget on the same job board. That helps if the problem is the ad. It does not help if the people you need are simply not on job boards. For nurses, electricians, drivers, warehouse staff and many hospitality roles, most of the right candidates already have a job and are not searching. You reach them where they scroll, not where they search.

• Check the ad first: is pay shown, is the title right, is applying quick on mobile
• Shorten the application. Ask two or three qualifying questions instead of a CV
• Add a channel that reaches passive candidates, such as Facebook, Instagram, TikTok or Snapchat
• Reply to applicants within a day. Slow replies lose people who applied elsewhere too
• Ask employees to share the role. Referrals often bring the best fits

Measure what matters

Tag every channel and campaign so your ATS records where each candidate came from. Without source tracking, you cannot tell which ads lead to hires, and budgets end up following clicks. Review the numbers weekly while a campaign runs, and keep a simple log of what you changed so you know what worked.

Common job advertising mistakes

• Paying for clicks without tracking whether they turn into hires
• Posting the same ad on every channel instead of adapting it
• Leaving out pay, which is the first thing most candidates look for
• A long application that loses people on mobile
• Relying only on job boards for roles with a candidate shortage

How SmartHire helps

SmartHire runs job advertising on Facebook, Instagram, TikTok and Snapchat aimed at people with the right experience, including the many who are not job hunting. Each campaign has its own short application page, candidates are screened against your requirements, and only those who match are delivered into your ATS with the source recorded. For most roles the first qualified candidates arrive within two to five days.

What is job advertising?

Job advertising is paid promotion of an open role to attract candidates, on job boards, professional networks, social media or programmatic platforms. It differs from a free job posting by paying for extra reach.

What is the best place to advertise a job?

It depends on the role. Indeed and similar boards suit active job seekers, LinkedIn suits office and specialist roles, and social media suits frontline and local roles where most of the right people are not looking.

How much does it cost to advertise a job?

Most platforms offer limited free listings and charge for promotion through an auction, per click or per application. Prices vary by role, location and competition, so run a small test and compare cost per qualified candidate.

What is programmatic job advertising?

Software that buys and places job ads across many sites automatically and moves budget to where it performs best, based on goals such as cost per application.

Are Facebook job ads worth it?

For frontline, hourly and local roles, often yes, because they reach people who are not on job boards. Employment ads have targeting restrictions, so the ad and a short qualifying application have to do the filtering.
