It is the first question in almost every initial conversation, and the one most often answered with a shrug and the words "it depends". It does depend - but not on nothing. There is published data on what Greek businesses spend and what a click costs in this region, and there is a practical floor below which the exercise stops compounding. Here is what can actually be said.
First, Separate the Two Numbers
Much of the confusion in this conversation comes from collapsing two different costs into one figure.
Media budget is the money that goes to Google, Meta or TikTok and buys clicks and impressions. It is the fuel.
Management is what you pay whoever plans, builds and runs the campaigns - an agency, a freelancer, or an in-house hire.
The two behave differently. Media budget scales with ambition and can be adjusted daily. Management is a relatively fixed cost whose floor has little to do with how much you spend on ads. Quoting them as a single blended number hides the question that matters: how much of what you pay buys reach, and how much buys judgement.
What Greek Businesses Report Spending on Media
The clearest published picture of this market comes from the State of Balkan eCommerce 2025 report, based on a survey of Greek online merchants conducted over the first nine months of 2025. On monthly advertising budgets it found:
- 34.0 percent spend up to €1,000 per month
- 24.5 percent spend between €1,000 and €5,000
- 32.1 percent spend more than €5,000
- 9.4 percent preferred not to answer
So around six in ten Greek eShops that responded operate below €5,000 a month, and roughly a third below €1,000. The same survey placed Google Ads first among channels at 41.5 percent of respondents, ahead of social advertising at 24.5 percent and SEO at 20.8 percent. Within social, respondents reported Facebook performing best at 45.3 percent, Instagram at 28.3 percent and TikTok at 11.3 percent.
Two caveats belong with those numbers. It is a survey of merchants who chose to respond, not a census, and it covers eCommerce rather than services or B2B. Treat it as the best available indication rather than as a definitive market measurement.
What a Click Costs
There is a genuine gap in the data here that is worth naming: I am not aware of a reliable published CPC benchmark isolated to Greece. If you see a precise Greek average CPC quoted across industries, it is worth asking what it is derived from.
What does exist is European ecommerce data at reasonable scale. Smarter Ecommerce's market observer, measured across roughly €650 million in European ad spend and reported in August 2026, put median CPCs at €0.43 for Search, €0.39 for Performance Max and €0.34 for Shopping.
For direction of travel, cross-industry Search CPC globally was reported at $2.96 in the first quarter of 2026, up from $2.64 a year earlier - a reminder that the trend across the market has been upward.
One addition since this was first written: ChatGPT Ads opened to Greek advertisers on 31 August 2026, so there is now a further channel in the mix with no established benchmarks at all. Budget for it separately rather than folding it into these figures.
The practical guidance is simple. Use the European medians as a planning anchor, understand that your own vertical may sit well above or below them, and expect your account to establish the real figure within a few weeks of running. Competitive verticals such as insurance, legal, private health and energy behave very differently from general retail, in Greece as everywhere else.
The Minimum That Actually Compounds
This section is professional judgement rather than published data, and I would rather label it as such than present it as fact.
The constraint is mechanical. Smart Bidding needs conversion volume to learn. A campaign running at roughly €10 a day, in a vertical with a €0.50 CPC, buys about 20 clicks a day. At a 2 percent conversion rate that is one conversion every two or three days. No bidding algorithm calibrates well on that signal, which leaves you either on manual bidding, capping what the account can become, or on automated bidding that struggles to leave the learning phase.
In my experience the level at which an account starts to compound rather than merely tick over is closer to €800 to €1,000 per month for lead generation and €1,500 to €2,000 for ecommerce - and only when the offer converts and the tracking is sound. Below that, the spend is not wasted, but it buys traffic rather than a system that improves month over month.
This also explains why the August 2026 change to target-based bidding matters unusually much in this market. At these budget levels campaigns sit almost permanently limited by budget, which is exactly the condition that change affects.
How Management Is Usually Priced
Rather than quote figures, which vary enormously by scope and seniority and date quickly, it is more useful to understand the three models in common use and how each behaves.
- Fixed retainer. Predictable for both sides. Needs revisiting if the scope of the account changes substantially in either direction, since the fee no longer matches the work.
- Percentage of ad spend. Common at larger budgets. At small budgets a percentage rarely funds meaningful senior attention, and the model ties the fee to spending more rather than to spending better.
- Hourly or project-based. Well suited to audits, migrations and fixed-scope builds. Less suited to ongoing optimisation, which is not a fixed-scope activity.
The useful question is not which model is cheapest, but which one aligns the incentive with the outcome you actually want.
The Number That Decides Everything
Every figure above is secondary to one you have to produce yourself: what a customer is worth to you.
Without it, a €25 cost per acquisition is neither good nor bad - it is a number floating free of context. With it, everything resolves. If a customer delivers €300 in gross margin over their lifetime, €25 is excellent and your constraint is volume rather than efficiency. If they deliver €40, €25 is precarious, and the problem is not in the campaigns.
A great many accounts that appear to have an advertising problem have a unit economics problem wearing an advertising costume. No amount of campaign work fixes an offer that cannot support the cost of acquiring a customer in its own market.
Questions Worth Asking Before You Commit
- Is media budget separated from management in the proposal? Both are easier to evaluate when they are not combined into one figure.
- What is assumed about tracking? If measurement is not discussed early, the reporting will be difficult to verify later.
- What does the first ninety days look like? Learning periods, conversion volume and the point at which results become readable are reasonable things to ask about in advance.
- How will performance be judged? Agreeing the metric, the window and the source of truth before starting prevents most disagreements afterwards.
The Short Version
In the Greek market in 2026, a realistic starting point for a business that wants performance marketing to compound rather than merely exist is in the region of €800 to €2,000 a month in media, depending on whether you are generating leads or selling products, plus management appropriate to the complexity of the account.
And before committing any of it, establish what a customer is worth. That single number determines whether every other figure on this page reads as cheap or expensive.
