“How much does Google Ads cost?” has no single answer, because the question covers three different costs: what you pay Google, what you pay whoever manages the campaigns, and what it costs for your website to turn a click into a customer. This article takes the bill apart piece by piece, with indicative prices for the Bulgarian market and the formula you can use to check for yourself whether your advertising pays off.
What the bill is made of
The first surprise for most businesses is that the ad budget is not the whole investment. Here are the three items you actually pay for every month.
Ad budget
The money that goes straight to Google with every click. You set the cap, daily or monthly. It is the only item you fully control.
Management
Setup, monitoring and optimisation. It is paid as a percentage of the budget, a fixed monthly fee or by the hour. A campaign that nobody manages burns budget quietly and predictably.
Landing page and tracking
One-off: a landing page that converts, and properly configured conversions. Without the latter your ads run blind, and Google optimises based on the data you give it.
How the price of a click is set
Google Ads is an auction, but not an auction on price alone. For every search, the system ranks the ads by a combination of the bid and the quality of the ad: how well it matches the query and where it leads. That is why two businesses that bid the same amount pay different prices.
The practical consequence matters: improving relevance cuts the bill more than cutting the bid. Ad text that matches exactly, a landing page on the topic of the query and a clean campaign structure lower the cost per click without lowering your position.
The auction punishes laziness. A campaign with one generic ad for fifty keywords pays a premium on every click, and keeps paying it every month.
Indicative cost per click in Bulgaria
The table below is an averaged picture from accounts we manage and is meant as a guide when planning a budget. Real figures vary considerably with the season, the competition and the quality of the campaign itself.
| Industry | Indicative cost per click | Note |
|---|---|---|
| Brand searches | €0.05-0.15 | Searches for your own name - the cheapest traffic |
| E-commerce, mass-market goods | €0.15-0.40 | High volume, low margin - conversion decides |
| Tourism and accommodation | €0.20-0.60 | Strongly seasonal |
| Home services and renovation | €0.40-1.20 | Local targeting, high-value searches |
| Medicine and dentistry | €0.60-2.00 | Advertising policy restrictions |
| B2B and industry | €0.50-2.50 | Low search volume, long decision cycle |
| Legal and financial services | €1.00-3.00 | The most expensive searches on the market |
These figures are indicative and they change. The only reliable estimate for your case comes from the Keyword Planner in Google Ads itself, which shows a forecast for the specific searches - free of charge, before you have spent a single cent.
What is the minimum budget that makes sense
Google has no minimum threshold: you can launch a campaign with €50 a month. The real question is a different one: at what budget do you collect enough data to optimise? Below a certain volume the campaign does not learn, and you cannot tell why it is not working.
With a small budget, the better approach is not to spread the money everywhere but to concentrate it: one service, one city, the most precise searches. A narrow, profitable account can be expanded. A broad, loss-making one cannot.
Management fees: the three models
| Model | How it works | When it fits |
|---|---|---|
| Percentage of the budget | Usually between 10% and 20% | For larger budgets, where the workload grows with spend |
| Fixed monthly fee | The same amount regardless of the budget | For small and medium budgets - the most predictable for the client |
| Hourly | You pay for the time actually worked | For a one-off setup or an audit of an existing account |
Be careful with “percentage of budget” models that have no cap. They create an incentive for the budget to grow, not the results. Ask explicitly: whose name is the account in, who has access, and what stays yours if you end the contract? The answer “our account” is a red flag.
The calculation that shows whether it pays off
Three numbers are enough: cost per click, conversion rate and profit per sale. Here is an example for an online store.
- Average order: €120, at a 30% margin → €36 gross contribution per order
- Cost per click: €0.35
- Conversion rate: 1.5% → about 67 clicks needed for one order
- Cost per acquisition: 67 × 0.35 = about €23
- Result: 36 − 23 = €13 contribution before the management fee
It pays off, but with a thin margin. And this is where you see why the conversion rate matters more than the cost per click: raising it from 1.5% to 2.5% brings the cost per acquisition down to about €14 and almost doubles the profit, without spending a cent more on advertising. That is why work on conversion optimisation often returns more than increasing the budget.
Five ways to burn your budget
- No negative keywords. You pay for “free”, “second-hand”, “jobs” and for your competitors. The first week of every campaign is for cleaning up the search terms report.
- Ads that lead to the home page. The user searched for something specific; the home page makes them search for it a second time.
- No conversions configured. Without them, Google optimises for clicks and you pay for traffic that does not buy.
- Display Network partner targeting left on by default. Impressions in apps and on random websites eat up the budget of the search campaign.
- Changing the settings every day. The algorithm is learning. A change every two days means a campaign that never leaves the learning phase.
When Google Ads is not the right choice
To be honest, advertising is not a universal solution. There are three situations in which the money is better spent elsewhere.
- Nobody is searching for what you sell. With a completely new product, demand has to be created first - a job for social media and content, not for search ads. This is where Facebook advertising comes in.
- The website is not ready. A slow site with an unclear offer turns paid traffic into a pure expense. The page first, then the ads.
- The margin cannot carry it. With a profit of €5 per sale and a cost per click of €0.50, the numbers do not work at any conversion rate.
If you are torn between paid advertising and organic visibility, the comparison is in a separate article: Google Ads or SEO: where should you invest first?
Conclusion
Google Ads costs as much as it brings you. For a small business offering local services, that means a realistic start of around €300 in budget plus a management fee. For an online store, from €500 upwards, knowing full well that the first six weeks are an investment in data, not in sales.
The number to watch is not the cost per click but the cost of acquiring a customer compared with what that customer brings you. Everything else is noise.
