Why is advertising for senior staff a false economy?

The “unqualified, unemployed, or unhappy” problem

Using advertising as a recruitment tool can produce results in some industry sectors, but for the appointment of senior personnel, advertising for senior staff almost always proves a false economy, because candidates responding to advertised senior roles usually fall into one of three recognisable categories: unqualified, unemployed, or unhappy. We’re not suggesting that advertising never draws good people, but generally speaking, it’s rarely the best or most cost-effective way of attracting high-calibre candidates with the capacity to create value for your organisation over the long term.

That argument was true when we first made it nearly a decade ago, and it’s arguably more true now. The recruitment landscape has changed dramatically since 2017: LinkedIn-led job advertising has become the default, AI-led tooling is now embedded in most applicant tracking systems, and the labour market for senior leadership has tightened materially. Yet the underlying problem with advertising for senior staff hasn’t gone anywhere. It’s simply moved channels.

The hidden costs of advertising for senior recruitment

The hidden costs of advertising for senior recruitment go well beyond the price of the ad itself. Even a modest campaign across LinkedIn, niche industry publications, and a couple of programmatic networks adds up, and the volume of response tends to overwhelm whoever is screening it. The quality of that response is the bigger problem. It’s a pattern frequently compounded by recruiters using generic role descriptions to maximise the volume of responders and the perceived value-for-money of the campaign, and the result is the wrong kind of inbox: hundreds of CVs, very few of which belong to people you’d actually want to interview, let alone appoint.

The senior internal time soaked up by that triage is rarely costed properly. Nor is the opportunity cost of the role staying open. A senior position unfilled for an additional two or three months while the advertised process plays out is two or three months in which the team isn’t led, the strategy isn’t set, and the work that needed doing doesn’t happen. That’s the part of the cost equation that almost never appears in the brief, and it’s typically the largest line on the bill.

What about LinkedIn and social? The modern advertising question

LinkedIn and social platforms haven’t rewritten the rules of senior recruitment; they’ve just made “advertising” lower-cost and faster, which is a different thing entirely. A sponsored job post on LinkedIn still depends on the same fundamental assumption that advertising has always depended on, which is that the right candidate is actively looking and will see the ad. At senior levels, that assumption holds for a small minority of the market and misses the rest.

The reality is that the senior leaders you most want to appoint are almost always already in post, contractually committed, and not visibly available. They aren’t scrolling job boards on a Sunday evening. They aren’t setting up LinkedIn alerts for openings at their own level. They’re running the businesses you’re trying to recruit from, and the only way to start a conversation with them is to approach them directly, discreetly, and on the basis of a brief worth their time. LinkedIn is a useful tool inside that process; it’s a poor substitute for it.

How AI is making the false economy worse, not better

The arrival of AI in recruitment was always going to cut both ways, and at the senior end it is cutting in the wrong direction, because the same generative tools that let a candidate produce a polished CV in minutes are flooding senior advertised roles with applications that look impressive on paper but don’t hold up in a serious conversation. The keyword-matching that drives most applicant tracking systems amplifies the problem, because the CVs that survive the first cut are now the ones written to game the algorithm, not the ones written by the leaders best suited to the role.

The flip side is no better. AI-led sourcing tools are excellent at producing long lists of candidates who look right on paper, and they’re close to useless at judging whether any of those people would actually take the call, do the interview, and accept the offer. The work that matters in senior recruitment, the discreet first conversation that turns a name on a list into a credible candidate, isn’t something an algorithm can do for you. If anything, the noise AI creates around senior advertised roles makes the underlying false economy worse, because it raises the volume of applications without raising the quality.

How headhunting works differently

Working with a professional headhunter to identify potential candidates is an entirely different process from advertising, because direct recruiting is a highly targeted, bespoke service in which the headhunter understands your requirements and the precise skills, experience, and track-record you’re looking for, and then identifies people who match the brief, whether or not those people happen to be looking.

Professional headhunting is a highly skilled methodology, and one that requires not only extensive industry knowledge and a network of professional contacts, but the credibility and judgement to approach senior people tactfully and ultimately persuade them to consider leaving their existing position. It’s a challenging task, and the rewards are usually worth it. The candidates identified through headhunting are almost always already talented, fulfilled, experienced, and in possession of a proven track-record of success. The benefits of headhunting are therefore two-fold: you appoint people with the expertise to add value from day one, and you appoint people who are ready to commit to your business and add greater value over the long term.

Isn’t headhunting more expensive than advertising?

Headhunting can cost more than advertising on the face of it, and if keeping the sticker price down is the primary motive, then an advertised process may feel like the appropriate solution; but if the objective is to appoint a high-quality candidate who’ll still be performing in three years, then headhunting is the clear winner. The cost comparison looks very different once you include the cost of time-to-fill, the cost of a mis-hire, and the cost of the work the wrong person doesn’t do.

It’s worth understanding the two principal commercial models. In retained headhunting, the client pays part of the fee up front and instructs the executive search firm to source a candidate that matches a specific brief, with the remainder of the fee typically split into additional payments at agreed milestones, often at shortlist and on appointment. In contingency recruitment, by contrast, the fee is only payable once a candidate is appointed, and the firm carries the search risk in exchange for a higher placement fee. In both models, the fee is typically structured as a percentage of the appointed candidate’s first-year remuneration, with rates in the UK senior market generally falling in the range of twenty to thirty-five per cent depending on the seniority, complexity, and exclusivity of the search.

The retained model exists because, at the senior end, you can’t run a search well on a contingency basis. The retained fee buys the consultant’s time, the research function behind the search, and the credibility to approach passive candidates without it looking like a fishing expedition. That’s the difference that makes the difference, and it’s the part of the work that advertising can’t replicate at any price.

A thought experiment for hiring managers

If you’re still not entirely convinced, here’s a thought experiment we’ve used in client conversations for years. Look at your own team as an example, the people you directly oversee day to day. That might be a handful of people in your department, or several thousand if you’re the chief executive of a large organisation. Do you think it likely that some of those people are currently exploring other opportunities, looking at job adverts, registering with recruitment agencies? Imagine ten per cent are doing exactly that, which isn’t an unreasonable assumption. And of the people who are actively looking to move elsewhere, do you think they’ll generally be the best-performing ten per cent of your team, or the worst-performing ten per cent?

Without actually running an anonymous survey to prove it, it’s safe to say that it’s more likely to be the under-achieving members of your team who are actively looking to move. It will be those who are unhappy in their current situation, those who aren’t committed, those who are struggling to deliver against their targets. That’s the problem with advertised senior recruitment in a single line: it disproportionately attracts exactly the wrong half of the market, because the right half isn’t looking.

By contrast, the candidates identified by a headhunter are selected on the basis of demonstrable expertise and a track-record of delivering results. They create immediate impact, and because they’ve made a conscious decision to take on a new role as a means of advancing their career, their motivations tend to be very different from someone who’s simply looking for another job. Engaging an executive search firm using a headhunting methodology produces better-qualified candidates who are more focused on delivering results, and the end result is achieved rather more efficiently, because the identification of candidates focuses on quality rather than quantity.
