Outsourcing your PPC: a profitability decision, not a comfort one

Paying a Google Ads consultant only makes sense if the net gain beats their fees. Below a certain media budget, it mathematically doesn't. Google's own documentation and agency landing pages push you to outsource the moment you touch paid search. In practice, I see the opposite all the time: small businesses paying €500 a month to manage €600 in ad spend. The math never works out.

The logic is simple. Say a consultant improves your campaigns by 25%, which is already a strong result. On an €800 monthly media budget, that gain is worth €200. If their fee runs to €500, you lose money by hiring them. The lever only becomes worthwhile once your volume is large enough that their optimizations generate more than their invoice.

What media budget justifies paying a consultant?

Below €1,000-1,500 in monthly media budget, outsourcing is rarely profitable for a small business. Fees eat up the potential gain, and the account stays too small to offer meaningful room for optimization. At €3,000 a month and above, the equation flips clearly: every point of ROAS gained pays off big.

According to France Num's digital barometer, most small and mid-sized businesses still commit modest advertising budgets to digital, often below the break-even point for outside help. That's not a minor detail. It means that for a large share of small companies, keeping things in-house or waiting remains the financially sound call.

In-house, agency, or freelancer: what does the math say?

You have three options, each with a very different cost structure. The table below compares the real total cost by media budget.

On an €800 budget, paying €400 to a freelancer means putting a third of your total budget toward management. To see where your money is really going, cross-referencing these costs with your priority digital marketing KPIs for running a small business keeps you from deciding on gut feel.

What does a Google Ads consultant really cost?

A freelance Google Ads consultant most often charges between €400 and €1,200 a month for ongoing management, or €50 to €90 an hour for a one-off audit. The spread comes down to experience, Google Partner certification, and the volume of accounts they manage.

What is the going rate for a Google Ads consultant?

Three pricing structures dominate the market: a fixed monthly fee, a percentage of media budget, and an hourly rate for one-off engagements. On platforms like Codeur.com, PPC freelancers frequently list day rates of €300 to €600. A serious account audit typically runs €400 to €800 depending on how deep it goes.

The €400 offer Google gives new advertisers has nothing to do with a consultant. It's a welcome ad credit: you spend a certain amount on ads, and Google credits your account up to €400. It's an incentive to get started, not a strategic engagement.

Flat fee, percentage of budget, or hourly rate: which model should you choose?

The percentage model creates a built-in conflict of interest: the more you spend, the more the consultant earns. A flat fee aligns interests better but can encourage passivity. Here's the trade-off for each option.

My advice: a flat fee with ROAS targets spelled out in writing. When I work with an e-commerce SMB, I almost always start with a one-off, hourly-billed audit before any monthly commitment, to gauge the account's real potential without locking anyone in. The details of bidding models and ad quality are documented in Google Ads' official help center.

The KPIs to demand before signing (and measure afterward)

The only metric that settles the in-house-versus-outsource debate is net ROAS: revenue generated, minus media budget, minus fees. Everything else follows from that line. A consultant who doesn't bring it up at the first meeting isn't selling performance, they're selling management hours.

How do you measure a Google Ads consultant's real ROI?

You lock in four numbers before the engagement starts, then compare them 90 days later. That before/after snapshot is the only objective proof of added value. Without it, you're paying on trust, never on results. Here's the framework I use.

CPA is what it costs you to win a customer. ROAS measures how many euros in sales each euro of ad spend brings back. Both figures show up in GA4 once conversions are set up, as explained in Google Analytics 4's official help center.

Which metrics should you track in GA4 and Google Ads?

Beyond ROAS, watch the Quality Score (the 1-to-10 quality rating Google assigns to your keywords) and the share of irrelevant search terms. An average Quality Score below 5 points to ads that are poorly matched to the queries. A high share of off-topic terms means you're paying for wasted clicks.

In early 2025, on a local tradesperson's account we were monitoring, simply excluding 40 irrelevant search terms cut CPA by almost a third in six weeks, without touching the budget. To structure this kind of review, our Google Analytics analysis method and the reports that actually matter breaks down the six reports worth following.

Checking these numbers yourself for a few weeks before signing shifts the balance of power in the negotiation. If you'd like us to look at your account together before making that call, our team answers directly on the contact page.

How to tell a good consultant from a passive account manager

A good Google Ads consultant optimizes structure and tracking. A passive account manager just watches the budget and switches on Performance Max. The difference shows up in a fifteen-minute conversation, as long as you ask the right questions, and you don't need to be technical to ask them.

Who is the best Google Ads consultant?

There's no absolute ranking. The best consultant for you is the one who understands your margins, your sales cycle, and your tracking. Be wary of "top" lists: someone excellent at e-commerce can be mediocre at B2B lead generation. The real signal isn't a list of awards, it's their ability to talk about your profitability, not their own.

Always verify their actual certification through the Google Partners program. A Partner badge confirms a minimum level of competence and managed ad spend. It's no guarantee of results, but it's a useful filter against improvised profiles.

What questions should you ask during the free audit?

Here's the screening checklist I hand to non-technical business owners. Ask these questions during the free audit and listen closely to how precise the answers are.

• How do you measure my conversions, and which tool reports them?
• What net ROAS are you targeting, and over what period?
• How do you handle irrelevant search terms week to week?

These first three questions already reveal a lot. A consultant who hesitates on measurement or gives a generic answer about ROAS isn't really optimizing, they're administering. Then move on to structure: how do they organize your campaigns by search intent? Will they turn on Performance Max, and why? What reporting do they provide, and how often? Someone who just sets up automated campaigns will stay vague on these points. A real optimizer will go into detail about your conversion tracking without you having to push.

Tracking first: why no ROI is provable without reliable measurement

Without GA4 conversions and Consent Mode V2 properly configured, the ROI any consultant claims is unverifiable. That's the big blind spot in sales pitches: you're sold optimization before anyone can measure anything at all. Measurement has to come before the engagement, never the other way around.

GA4 conversions, Consent Mode V2, and server-side tracking: what are they?

A GA4 conversion is an action you want to measure: a purchase, a submitted form, a call. Consent Mode V2 is the mechanism that adjusts measurement based on your visitors' cookie consent, required in Europe since March 2024. Without it, part of your conversions stay invisible and your numbers understate reality by default.

Server-side tracking (collecting data on the server rather than in the browser) makes measurement even more reliable against ad blockers. According to Google's documentation on advanced measurement, a growing share of conversions slip past classic browser tracking. For a small business, the stakes are simple: a consultant optimizing on incomplete data is optimizing in the dark. Our step-by-step method for making Google Ads conversion tracking reliable in GA4 lets you lock down this measurement before you sign anything.

Before any engagement, I always spend half a day checking the tracking. On the accounts we work with, conversions are often misfiring or counted twice. Fixing that sometimes moves the reported profitability more than six months of optimization would. Our guide to managing SEO with Search Console usefully rounds out this measurement foundation.

Verdict: outsource, keep it in-house, or wait, depending on your situation

Outsourcing becomes a clear win past €1,500 in monthly media budget, with clean tracking and a numeric ROAS target. Below that, it's better to keep things in-house or wait. Here's my verdict by profile, based on real situations we've seen across several accounts. If your hesitation is more about a bigger setup, our comparison, Google Ads agency: outsource or manage it in-house, applies the same threshold framework.

Cases where a consultant is clearly worth it

For a 10-to-50-person e-commerce business spending €4,000 a month, outsourcing is almost always worth it. On one case we tracked internally, moving ROAS from 3.2 to 4.5 in four months generated several thousand euros in extra margin, well above the €900 in fees. At that volume, every point of ROAS carries real weight.

B2B services with a long sales cycle also benefit from outsourcing, provided the consultant can track leads all the way through to the CRM. Here, raw ROAS often lies: only full attribution reveals the real value. Our article on marketing attribution and which channel actually drives your sales explains why last-click attribution misleads small businesses.

Cases where it's better to keep it in-house or wait

For a local tradesperson spending €600 a month on a handful of geo-targeted keywords, paying a consultant €400 makes no sense. The account is too simple and too small. A few hours of training are enough to run basic local campaigns yourself, and an expert's gain would never cover their invoice. Before you even settle that debate, check that the channel is worth it in the first place: our analysis, Google Ads for small businesses: is it actually profitable?, gives the thresholds by company size.

Same logic for a small business just starting out without reliable tracking. As long as conversions aren't measured, outsourcing means paying to fly blind. Fix the measurement first, run a small test budget, then decide. Patience costs less than premature outsourcing.
