Should you outsource PPC management? A decision framework for in-house teams
"Outsource or keep in-house" gets answered on cost too often, and on capability too rarely. The framework that separates the businesses that should outsource from the ones that shouldn't.
The "should we outsource PPC management?" question gets answered on cost more often than it should. The honest answer depends on four things — capability, capacity, complexity and continuity — and the right call varies by where each of those sits in your specific business. Get the analysis right and you save 6-12 months of "this isn't quite working" before you switch.
Here's the framework we use when prospects come to us asking whether to outsource. Sometimes our recommendation is "yes, hire us"; sometimes it's "no, keep this in-house"; sometimes it's "neither — hire someone else specifically".
The four factors that decide it
1. Capability — is the right expertise available internally?
Honest assessment: does someone on your team know Google Ads well enough to make good structural decisions, not just execute on them? Two different things.
Execution skills (running campaigns, monitoring metrics, running A/B tests) can be learned in a year of dedicated work. Structural decision-making (when to restructure, which bidding strategy fits the volume, how to structure conversion tracking) takes 5+ years of varied accounts to get right.
If you have execution but not structural, you can hire a part-time consultant (4-8 hours a month of senior time) to make the structural calls while in-house executes. This is a hybrid worth considering, not just a pure in-house vs outsource choice.
If you have neither, outsource. Building both internally is a 2-3 year project; a £200k+ commitment in salary plus tools plus time. Most businesses don't justify that cost against their PPC spend.
2. Capacity — does the work actually need a full-time person?
The mistake people make: they hire a Google Ads manager full-time, then realise the role only needs 2 days a week of actual PPC work. The other 3 days fill with reports, meetings, and "strategy" projects that don't move the numbers.
Rough scaling guide:
- Under £5k/month spend: 8-15 hours a month of management work. Doesn't justify a hire. Outsource.
- £5-15k/month spend: 20-40 hours/month. Could be 0.5 FTE in-house, or fully outsourced. Cost is similar; the question is which gives better quality.
- £15-50k/month spend: 1 FTE worth of work. Either 1 in-house manager or a dedicated agency relationship.
- £50k+/month spend: 1-2 FTE worth, plus specialist help. Usually in-house manager + agency or consultant for senior strategy.
Below £15k/month, the in-house route requires you to find someone willing to do PPC half-time alongside other duties. That hire is harder than it sounds — most senior PPC people want full-time PPC roles or full-time consultant lives, not split roles.
3. Complexity — is this work standard or unusual for your category?
Standard categories (e-commerce with normal product feeds, B2B lead-gen with normal sales cycles, local services) have well-known PPC playbooks. The expertise needed is broadly available. Either in-house or outsource works.
Unusual categories (regulated sectors, marketplaces with attribution complexity, businesses with very long sales cycles, extreme seasonality, multi-stage conversion funnels) need specialist expertise. The pool of people who've actually run PPC for your specific category is small. Outsourcing to a specialist who's worked in your space is faster and cheaper than training someone in-house.
Test: how many businesses with your category profile are running successful Google Ads accounts? If the answer is "many", standard. If the answer is "few", specialist.
4. Continuity — what happens if the person leaves?
The single biggest failure mode of in-house PPC: the experienced person leaves, taking institutional knowledge with them, and the account drifts for 3-6 months while a replacement gets up to speed.
A consultant or agency relationship has structural continuity in a way an individual hire doesn't. Even if your account-team rotates inside the agency, the agency retains the account history, the documentation, the access. Replacement is faster.
If your business genuinely depends on PPC performance (more than 30% of revenue tied to it), the continuity argument tilts toward outsourcing. The risk of a 6-month gap from an in-house departure is often more expensive than the agency premium.
If PPC is a small minority of your acquisition, an in-house hire is fine — a gap won't break the business.
When outsourcing is clearly right
Combine the four factors. Outsource when:
- Capability isn't strong internally, AND
- Capacity needed is part-time or volatile, OR
- Complexity is high and you don't have category-specific expertise, OR
- Continuity matters because PPC is a major revenue driver
Two or more of those = outsource is probably right.
When in-house is clearly right
The reverse pattern. In-house when:
- Capability is genuinely strong internally (you have a senior PPC person, not someone learning), AND
- Capacity is full-time at your spend level, AND
- Complexity is normal for your category, AND
- Continuity risk is manageable (good documentation, succession-planned)
All four = in-house is the right call. Most businesses don't have all four; that's why most of them outsource at least some of the PPC work.
The hybrid model that's underrated
There's a third option neither side of "outsource vs in-house" usually presents: in-house execution with outsourced senior strategy.
How it works: you hire a junior-mid PPC executor in-house (£35-50k/year, well within your existing team's budget), and contract a senior consultant for 4-8 hours/month of strategic oversight. The consultant doesn't run campaigns; they review structure, sign off on bid strategy choices, audit conversion tracking, and provide a senior pair of eyes on monthly performance.
Total cost: £35-50k + £600-1,200/month consultant = £42k-65k/year. Equivalent to a single mid-senior in-house hire, but with a much higher ceiling on quality.
This works best for accounts at £8-25k/month spend where you have enough work to justify partial in-house, but not enough to justify a senior in-house operator.
We do this hybrid arrangement for several clients — typically 6-8 hours/month of senior time alongside their in-house executor. Worth considering if pure outsource feels like overpaying and pure in-house feels like underqualified.
The cost comparison nobody runs properly
Most "outsource vs in-house" comparisons go: "agency is £3k/month, in-house hire is £4k/month, in-house wins". That's not the comparison.
Real cost comparison includes:
- Salary plus on-costs for in-house: salary × 1.25-1.30 (NI, pension, benefits)
- Tools and platforms: SEMrush, Optmyzr, Looker Studio, etc. — £200-500/month if not already paying for them
- Recruitment: 15-25% of salary for the placement, amortised over expected tenure
- Management overhead: someone has to manage the PPC manager. 2-4 hours of senior time/week.
- Training and conferences: £2-5k/year to keep an in-house person current
- Time-to-productivity: 3-6 months before a new in-house hire is operating at full capability
Versus an agency or consultant:
- Retainer fee
- Tools usually included
- Productive from day 1 (or week 1)
- No management overhead beyond performance review
For accounts under £20k/month spend, the all-in cost of in-house is often higher than the agency retainer once everything is counted. The "in-house is cheaper" story usually doesn't survive proper accounting.
What we recommend
For most businesses spending £3-15k/month on PPC: outsource to a specialist. The economics and quality argument both favour it at that scale.
For businesses spending £15-50k/month: the hybrid model. In-house execution + outsourced senior strategy.
For businesses spending £50k+/month: in-house manager backed by either an agency for execution capacity or a senior consultant for strategy.
