If you run a small business in Ireland and are considering Google Ads, the first question is usually the same: how much should I spend?
The honest answer is not a fashionable round number. Your budget should be calculated from the cost of reaching a qualified searcher, the percentage of visitors who enquire, the percentage of enquiries you close, and the value of a new customer.
Google confirms that there is no minimum spending commitment. You control the budget. That flexibility is useful, but it also means Google will happily run a campaign with a budget too small to produce reliable information. The correct budget is the smallest amount that can generate enough qualified clicks and conversions to make a sound commercial decision.
The quick answer
For a focused local campaign in Waterford or Kilkenny, a small service business can test Google Search Ads with roughly €600 to €1,500 per month in ad spend. Competitive sectors, wider service areas or high-value services may require €1,500 to €3,000 or more.
That is a planning range, not a promise. A single-service campaign targeting one county needs less data than a campaign covering ten services across Ireland. Legal, finance, healthcare, construction and emergency services can also carry very different click costs.
Management, landing-page work, call tracking and creative production are separate from the media budget paid to Google.
Calculate the budget backwards
Do not begin with what feels affordable. Begin with the result the business needs.
Use this sequence:
- Target number of new customers
- Close rate from qualified enquiry to customer
- Website conversion rate from click to enquiry
- Estimated average cost per click
Imagine a physiotherapy clinic in Waterford wants ten new patients from search ads this month. The clinic closes half of its qualified enquiries, so it needs twenty enquiries. If the landing page converts 8% of visitors, it needs about 250 qualified clicks. At an estimated €2.50 per click, the working media budget is €625.
The calculation is:
Required customers ÷ close rate ÷ website conversion rate × cost per click = estimated media budget
If the page converts at only 2%, the same target needs 1,000 clicks and approximately €2,500. This is why sending more paid traffic to a weak page becomes expensive very quickly.
Is €300 per month enough for Google Ads?
Sometimes, but only for a narrow test.
A €300 budget is about €9.87 per day when divided by Google's average 30.4-day month. That may work for one service, a small radius and lower-cost search terms. It will struggle when several campaigns, locations and services compete for the same small pot.
A low budget can also create false conclusions. If the campaign buys too few clicks, one good or bad week can distort the result. You may pause a viable channel before it has collected enough conversion data, or keep a weak campaign because one accidental enquiry made the numbers look better than they are.
Use €300 when the scope is deliberately restricted and the test question is specific. For example: can searches for one named treatment within 15 kilometres of Kilkenny generate qualified calls?
What changes the cost in Ireland?
Your sector
The value of a customer affects what competitors will bid. A solicitor, mortgage broker or commercial contractor can justify a higher cost per enquiry than a low-ticket retail service.
Your location and radius
Waterford and Kilkenny can be less expensive than Dublin for some terms, but smaller markets also have lower search volume. Expanding to all of Ireland increases reach and competition. A local campaign should target only places the business can serve profitably.
Search intent
A person searching "emergency electrician Waterford" is closer to buying than someone searching "how does rewiring work". High-intent searches can cost more, but they can also produce better leads.
The landing page
Google Ads does not repair a confusing website. The page needs a clear service, location, proof, price context where appropriate, one obvious action and a form that works properly on mobile.
Tracking and follow-up
If calls, forms and booked appointments are not tracked, the campaign cannot be managed against revenue. If enquiries wait until the next day for a response, the advertising may be blamed for a sales-process failure.
Google may spend more on an individual day
Google Ads uses average daily budgets. Google explains that the platform can spend up to twice the average daily budget on a particular day for many campaigns, while keeping charges within the applicable monthly spending limit.
This matters for cash-flow planning. A €30 average daily budget does not mean the account will spend exactly €30 every calendar day. Review the budget report and monthly limit, not one isolated day's spend.
Set the number that protects your margin
The most important number is your maximum affordable cost per acquired customer.
If a new customer is worth €1,000 in gross profit and you are prepared to invest 20% of that profit in acquisition, your target acquisition cost is €200. If half of qualified enquiries become customers, the target cost per qualified enquiry is €100.
That gives the campaign a commercial boundary. Without it, "more leads" can look successful even while the business loses money.
A sensible first-month structure
For most Irish service businesses, the cleanest first test is:
- One high-value service
- One defined location or service radius
- A short list of high-intent keywords
- Negative keywords to block irrelevant searches
- One dedicated landing page
- Call, form and booking conversion tracking
- A written response and follow-up process
- Weekly review of search terms, lead quality and cost
Do not spread a starter budget across Search, Display, YouTube and several automated campaign types. Prove one route to revenue first.
What to do this week
1. Decide how many new customers you actually need next month. 2. Calculate your maximum affordable cost per customer and per enquiry. 3. Check whether the landing page and follow-up process can convert the traffic before increasing spend.
If you need the website, tracking, advertising and follow-up connected as one system, review Oconcept's client acquisition services.
Frequently asked questions
What is the minimum Google Ads budget in Ireland?
Google sets no minimum spending commitment. In practice, the budget still needs to buy enough relevant clicks to test whether the campaign converts.
Is €500 enough to test Google Ads?
It can be enough for one tightly targeted local service. It is unlikely to support several services or a national campaign reliably.
Should management fees come from the ad budget?
No. The ad budget is paid to Google. Strategy, setup, management, landing pages and tracking are separate business costs.
How long should the first test run?
Run long enough to collect meaningful click and conversion data. For many local businesses, four to six weeks is more useful than judging the campaign after a few days.
