A small business in Greece starting with Google Ads should expect a minimum useful budget of €300 to €600 per month in ad spend, plus a management fee of €250 to €600 per month if an agency runs it. Below roughly €10 a day, the campaign rarely gathers enough data to optimise.
Why there is a floor
Google needs conversions to learn. A budget that produces two or three clicks a day takes months to reach a signal, and by then you have spent the money learning nothing. It is usually better to run one tightly focused campaign properly than three underfunded ones.
What the budget depends on
- Your cost per click. Legal, medical, and construction terms in Greece can run €1–4 per click; local services and niche products are often far cheaper.
- Your margin. A €40 haircut and a €4,000 kitchen justify very different budgets.
- Your close rate. If one in three enquiries becomes a customer, you can pay more per enquiry.
A simple test for month one
Pick one service, one location, and a landing page that matches the ad. Run it for 4–6 weeks. Track calls and form submissions, not clicks. Then calculate cost per enquiry and cost per customer. If a customer costs less than they are worth to you, scale. If not, fix the page or the targeting before adding budget.
The most common waste
Sending paid traffic to a homepage instead of a page about the exact thing the person searched for. The ad can be perfect and still fail there.
