There aren't two ways to run Google Ads — there are three: do it yourself, hire a coach to teach you, or hire an agency to run it for you. Most "coach vs agency" articles quietly drop DIY, even though it's where almost everyone starts. Below, each option is ranked by overall fit for typical advertisers, then scored against the criteria that actually matter.
TL;DR — Quick comparison
| Aspect | DIY | Coach | Agency |
|---|---|---|---|
| Cost | €0 + your time (and learning waste) | Low upfront — sessions or modest retainer | Higher monthly fee or % of ad spend |
| Speed | Slow — you learn by trial and error | Fast fixes if you implement | Slower onboarding, faster for scale |
| Skill you keep | Eventually, but unstructured | Builds lasting in-house capability | None — capability leaves with them |
| Control | Full | Full — you keep account & data | Agency often controls structure & reporting |
| Best for | < €500/month, pure bootstrap | €500–€10K/month, want to own it | €10K+/month, multi-channel, no time |
The real difference
DIY means you learn and run it; a coach teaches you to run it well; an agency runs it for you. They're not rivals so much as sequential stages — most advertisers move through them as budget and complexity grow. The mistake is staying in one too long: DIY past the point where waste exceeds a coach's fee, or jumping to an agency before you can evaluate one.
1. DIY (Do It Yourself)
Do It Yourself
With free resources — Google Skillshop, YouTube, blogs (like this one) — you can get a campaign live and learn the basics. At a tiny budget it's the rational choice. The hidden cost is learning waste: the months of mis-set bids, broad-match leakage, and broken conversion tracking you pay for in spend while you figure it out, with no one to catch the expensive mistakes.
- No fees — lowest cash cost
- Full control and ownership
- You learn at your own pace
- Slow; trial-and-error waste
- No one to catch costly mistakes
- Outdated, conflicting advice
Verdict: The right start at very small spend. The moment monthly waste exceeds a coaching fee, you've outgrown it.
2. Google Ads Coach
Google Ads Coach
A coach works on your account and teaches you the levers as you fix them — compressing months of DIY learning into a few sessions while you keep full control. The high-value work is exactly what burns DIY budgets: bidding strategy, match types, conversion tracking, and account structure. Because the skill stays in-house, the improvements keep paying off long after the sessions end.
- Skill stays in-house and compounds
- Fast, high-impact fixes
- You keep account & data control
- Low upfront cost vs an agency
- You (or a teammate) still execute
- Requires a few hours of your time
- Quality varies — pick carefully
Verdict: The default for hands-on owners who want a repeatable system they own. Learn more about our coaching →
3. Google Ads Agency
Google Ads Agency
Agencies are right when your funnel and offer are validated, you spend €10K+/month, and execution capacity — not capability — is the bottleneck. They bring teams, processes, and multi-channel execution across Search, Performance Max, YouTube, and display. The risk is information asymmetry: outsourcing what you can't yet evaluate, and accepting blended reports that hide where waste lives.
- Fully done-for-you execution
- Capacity to scale multi-channel
- Team depth and process
- Expensive below €10K/mo spend
- No skill retained; vendor lock-in
- Blended reporting can mask waste
Verdict: Right when capacity is the constraint — ideally hired after coaching so you can judge their work. See managed ads →
Scorecard — which wins on what
No option wins everything. Pick the column that matches what you're optimizing for right now:
| Criterion | Winner | Why |
|---|---|---|
| Lowest cash cost | DIY | No fees — but you pay in learning waste. |
| Fastest fix | Coach | Targeted, expert changes in days, not months. |
| Skill you keep | Coach | Capability stays in-house and compounds. |
| Least of your time | Agency | Fully done-for-you once onboarded. |
| Scaling multi-channel | Agency | Team capacity across Search, PMax, YouTube. |
| Control & ownership | DIY / Coach | You keep the account, data, and decisions. |
| Best value, €500–€10K/mo | Coach | Highest return per euro at typical budgets. |
The hybrid stage most people miss
The highest-leverage route is usually: coach first, then hire an agency or build in-house. A coach sets clean structure, measurable KPIs, and documents processes so you know what "good" looks like when an agency takes over.
Without that foundation you risk information asymmetry — outsourcing what you can't evaluate — and paying for delegation rather than performance.
The Math: €200 vs €2,000/month
Concrete scenario: you spend €5,000/month and 40% is wasted (~€2,000/month). A coach can diagnose and fix structural issues in 1–2 sessions (e.g., €200/session × 2 = €400) delivering immediate monthly savings. An agency retainer at €2,000/month often takes 2–3 months to fully optimize, meaning higher upfront fees before waste is materially reduced.
Before: a small DTC home-goods brand, €6,200/month on Google Ads, working with a boutique agency for 8 months. Reported account-blended ROAS: 3.4×. The agency's monthly report led with this number every cycle.
After session one: we split brand-search out of the Performance Max campaign. Once branded clicks were excluded, real prospecting ROAS was 1.3×. Two-thirds of the "ROAS" had been people Googling the brand by name.
Sessions two and three: killed two underperforming PMax asset groups, rebuilt conversion tracking (purchase event was double-firing), and rebalanced budget toward two product categories that actually had margin.
End state, 90 days later: €4,700/month spend (24% lower), real prospecting ROAS 2.6×, new-customer count up 31%. Three coaching sessions cost €600 total. Monthly waste removed paid that back in week two.
My Contrarian Take — Reporting Hides Waste
Most agencies are competent; many simply present aggregated metrics that mask underperforming segments. Reporting tricks — like blended ROAS or CPA across campaigns — can make a program look healthier than it is.
Ask any vendor for campaign-level ROAS, prospecting vs retargeting splits, and product-level contribution margins; those breakouts show where waste actually lives.

Frequently Asked Questions
Should I run Google Ads myself or hire someone?
Run it yourself while spend is very small (under ~€500/month) and you're learning. Once monthly wasted spend exceeds what a coach would cost, hire a coach to compress the learning and keep control. Move to an agency only when your funnel is validated, you spend €10K+/month, and execution capacity—not skill—is the bottleneck.
How much does coaching cost?
Typical coaching ranges from €100–€400 per session or €200–€800/month for ongoing advisory, depending on experience and scope.
Can I do both at once?
Yes. Many clients keep a coach while hiring an agency—coaches act as strategy reviewers and accountability partners to ensure the agency focuses on the right levers.
What if I already have an agency?
Bring coaching in as an audit and governance layer; a coach helps interpret reports, push for better segmentation, and ensure inefficiencies aren't hidden behind blended metrics.
How long until I can run it myself?
With focused coaching and weekly practice, many owners achieve basic competence in 4–8 weeks; mastery takes longer depending on complexity.
Is there a middle option?
Yes: hybrid models (coach + part-time freelancer) or an in-house marketer trained by a coach often outperform pure-agency setups in the €3K–€15K/month range.
