When Should You Bring Paid Media Management In-House?
A practical way to decide whether your organisation needs a permanent paid media employee, an agency or fractional specialist support.
At some point, every growing business asks whether it should stop outsourcing advertising and hire someone internally. Sometimes that’s exactly the right move. Sometimes it creates a new problem: a single employee is suddenly expected to be the strategist, platform expert, analyst, creative reviewer and emergency troubleshooter across every channel.
The right answer depends on the size and complexity of the work, not simply whether an in-house role feels more permanent.
What are you actually trying to solve?
Before drafting a job description, work out what isn’t working today.
Is the agency too slow to implement changes? Do you lack visibility into decisions? Is your internal team struggling to coordinate offers and landing pages? Are you paying for skills that rarely get used? Or do you genuinely need a specialist available throughout the week?
Different problems require different fixes. If the issue is tracking or account structure, replacing the provider may not solve it. If the issue is daily coordination between merchandising and media, bringing someone closer to the business may help considerably.
Signs that an in-house role could make sense
Paid media requires significant daily coordination
If advertising decisions depend on changing inventory, promotions, sales feedback and creative approvals, close collaboration can be valuable. A full-time employee can spend more time with colleagues and respond quickly to commercial changes.
There’s enough work for a genuine specialist role
A business spending across several active channels, markets and product lines may have a sustained workload beyond occasional optimisation. But distinguish necessary work from activity for activity’s sake. More meetings and reports don’t automatically mean more management value.
You can support the hire properly
A capable paid media lead needs access to commercial information, creative resources, tracking support and decision-makers. Hiring one person without those foundations can create unrealistic expectations.
You want to build internal knowledge over time
An in-house team can help develop stronger organisational understanding of customers, offers and what drives performance. That knowledge becomes particularly valuable when acquisition is central to the business.
Reasons to consider a fractional specialist first
For many businesses, there’s a gap between needing specialist ownership and needing a full-time hire.
A fractional Head of Paid Media can provide senior strategy, hands-on campaign management and collaboration with an existing marketing team on a defined number of days or deliverables.
It can be useful when you need to stabilise accounts, establish measurement, improve reporting or find out what workload the eventual permanent role should cover.
You can also use a fractional specialist to support or mentor a junior employee rather than expecting that junior hire to own every strategic decision.
When an agency is still the better fit
If you need large-scale creative production, specialists across many platforms, continuous operational coverage or international coordination, an agency’s broader team may be valuable.
The critical point is to establish who actually manages campaigns and whether strategic decision-making is connected to execution. A large team isn’t inherently better if accountability is unclear.
Calculate the full cost, not just the salary
An in-house hire involves more than the advertised salary. Consider recruitment, employer costs, equipment, training, software, management time, leave coverage and the cost of a vacancy.
An external engagement may have separate charges for creative, analytics or development. Compare like for like by listing responsibilities and costs across each option.
For example, if you need Google Ads management, LinkedIn campaign builds, landing-page feedback and weekly reporting, write those deliverables down before asking anyone for a quote or setting a salary band.
Make a responsibility matrix
I find it useful to map out four categories:
| Responsibility | Who should own it? |
|---|---|
| Channel strategy and budget allocation | Senior marketing/paid media owner |
| Campaign builds and ongoing optimisation | Named hands-on specialist |
| Creative production and landing pages | Internal or designated external team |
| Data, tracking and CRM integration | Marketing operations or technical specialist |
One person can cover several areas, but everyone needs to know the actual arrangement. Ambiguity is what creates delays and missed work.
Don’t make the decision entirely about media spend
A business spending £15,000 a month on several technically complex B2B programmes may require more specialist attention than one spending substantially more on a relatively simple ecommerce setup.
Consider campaign complexity, volume of changes, measurement requirements, product breadth and number of stakeholders alongside the media budget.
A sensible transition plan
If you do bring paid media in-house, avoid switching everything overnight.
Ensure the business owns platform accounts and critical data. Document campaign objectives, budgets, conversion goals, audiences, existing tests and recurring tasks. Transfer access and reporting responsibilities deliberately.
For the first month, prioritise continuity and measurement before making a wholesale restructure just to show progress.
The bottom line
Bring paid media in-house when there is sustained work, the role is properly supported and closeness to the business will improve decisions. Use a fractional specialist when you need senior capability without a full-time workload. Use an agency when broader delivery capacity is a meaningful requirement.
The best model is the one with clear ownership and effective execution.
