Are Google Ads Worth It for a Small Business in Ireland?

Google Ads are worth it when a customer brings you more profit than the clicks it takes to win one.

That’s the whole test. The management fee, the daily budget, the agency pitch and the horror stories are all detail around that one sum.

Ask the question in any small business group and the answers split down the middle. One camp calls Google a bottomless pit. The other says it’s the only advertising that ever paid for itself. Both are usually telling the truth about their own accounts.

What separates them is often whether the numbers worked before the first euro went in, and whether anyone was counting the calls once it did.

Do Google Ads actually work?

Yes, but only for the customer who is already searching.

Someone types “emergency plumber Navan” or “solicitor for a house sale Galway”, and your ad can answer them straight away. They’ve told Google what they want, in their own words. Little other advertising starts that close to a sale.

That’s also where it stops working. If nobody searches for what you sell, there’s nothing for an ad to answer. A new product people don’t know to search for yet, or something they buy on sight, is a job for Facebook and Instagram, which put an offer in front of people who weren’t looking. We compare the two in Google Ads vs Facebook Ads.

Search demand is the first condition. The second is the sum.

How to work out if Google Ads are worth it for your business

You need four numbers. Three you already know, or can guess well. One comes from Google.

1. What a click costs for the searches you’d pay for, in your area. Google’s Keyword Planner gives an estimate.
2. How many clicks it takes to get an enquiry. If one visitor in ten rings or fills in your form, that’s ten. It’s the shakiest of the four, so run the sum at one in ten and at one in twenty.
3. How many enquiries it takes to win a job. If you win one quote in three, that’s three.
4. What a customer is worth to you in profit, not turnover. If they come back, count what they’re worth over the years they stay.

Multiply the first three together and you have what it costs to win a customer. Put it beside the fourth.

If winning a customer costs comfortably less than that customer is worth to you in profit, Google Ads are worth it. If it doesn’t, no amount of clever targeting will fix it. Better targeting moves the first number a little. It can’t make a job that leaves you €60 profit pay at €8 a click.

A worked example. Say you’re a roofer. The middle price of a roofer click across Irish counties is €2.75. One visitor in ten enquires and you win one quote in three, so it takes thirty clicks to win a job. That’s €83 to win a customer.

If a typical job leaves you €1,500, that’s a trade you’d make all day. If most of your work is a gutter repair that leaves you €150, you keep €67 at best. At one visitor in twenty, winning the customer costs €165, so aim the ads at the bigger jobs.

If you’re a charity, the sum is different: Google Ad Grants can give an eligible charity up to $10,000 USD a month of Google Search advertising at no cost. If you sell products online, the sum is the margin on each product against what a click costs, and Google Shopping ads work it product by product.

What it costs to win a customer, trade by trade

Click prices vary more by trade than by anything else. In Google Ads keyword data for Irish searches, the middle price of a restaurant click in an Irish county is about 17 cent. For a mortgage broker it’s close to €10.

The last column uses the roofer’s example: one click in ten becomes an enquiry, one enquiry in three becomes a job. Put in your own rates and the answer moves. The gap between trades doesn’t.

Click prices are Google Ads keyword data for Irish searches, pulled through DataForSEO in September 2026 and converted from US dollars at the ECB reference rate (€1 = $1.146, 18 September 2026).

The middle price is the median, the county in the centre when you line them up from cheapest to dearest. Only counties with at least 30 searches a month for the trade count are included (five to 26 counties a trade, fewest for IT support). The range leaves out the cheapest and dearest quarter, so one odd county can’t stretch it.

Read it the other way round too. €285 to win a customer can be a bargain for a mortgage broker and would sink almost any hairdresser.

Where you are matters less than what you do, but it still matters. Taking all trades together, the middle click runs from €1.00 in Monaghan to €2.71 in Dublin, the cheapest and dearest of the counties we have pages for. Those pages carry the prices for Dublin, Cork, Galway, Limerick and eleven more counties.

How much should a small business spend on Google Ads?

Google leaves the amount to you. Its help page on managing spend says the amount of your budget is “entirely up to you and you can edit this amount whenever you like”.

What a budget buys depends on your trade. Google counts a month as 30.4 days, so €10 a day is €304 a month. Here’s what three budgets buy three trades, with the same one-in-ten enquiry rate. At one in twenty, halve the enquiries.

Is €10 a day enough for Google Ads?

In a cheap trade, yes, to start. About seventeen enquiries a month gives a plumber something to learn from.

In a dear trade, no. Three enquiries a month in solar tells you almost nothing, because one good week or one bad one swings the whole result.

There’s a second problem. Google says its automated bidding can take up to around 50 conversions, or three conversion cycles, to finish learning. Three enquiries a month gives it very little to learn from. A small budget in a dear trade has to be run by hand, on a short list of exact searches, or it drifts.

Is €500 a month enough for Google Ads?

It is if your clicks cost a few euro or less and you keep the campaign to one service in one area, on the exact searches a customer would type. Spread €500 across five services and three counties and none of them gets enough to prove anything.

Is €20 a day enough for Google Ads?

For most local service businesses outside the dearest trades, €20 a day is a fair test. It buys a roofer around 220 clicks a month, which at one in ten is about twenty-two enquiries. That’s enough to see which searches bring work and which only bring clicks.

Will Google spend more than my budget?

On a single day, it can. Over a month, it won’t.

Google lets a campaign spend up to twice its average daily budget on a busy day. Across the month, you’ll never be charged more than 30.4 times the daily budget. Set €10 a day and a Tuesday might cost €20, but the month can’t cost more than €304.

In the first week, a couple of €20 days can look like something’s broken. Nothing is.

When Google Ads aren’t worth it

Sometimes the answer is no, and it’s usually one of these.

• The job is too small for the click. If the table says winning a customer costs €247 and your average job leaves you €80, stop there. That’s IT support call-outs for home users, and plenty of other trades besides.
• You can’t take the work. If you’re booked out for six weeks, ads fill a diary that’s already full, and a customer who waits a month for a callback doesn’t stay a customer.
• Nobody answers the phone. The customer you spent €83 to win rings while you’re up a ladder, and gets no answer. Ads pay best for businesses that answer, or ring back the same day.
• You can’t tell which calls came from the ads. This is the one that turns “worth it” into “no idea”. Google Ads can count calls from the ad and from your website, so set that up before any money goes out. Our Google Ads audit checks tracking first, calls included, and our audit checklist is the do-it-yourself route.
• The page the ad lands on doesn’t convert. If that page is slow, vague or ends in a form nobody fills in, you pay for the visit and lose the customer. Fix the page first.
• Word of mouth may already be cheaper. If most of your work comes from referrals, rewarding customers who send you a friend can win new customers for less than a click campaign would. Price both before you choose.

A management fee bigger than the spend is a separate question, and the next section covers it.

Should you run Google Ads yourself or pay someone?

Google asks for no minimum spend, and you pay it for the clicks. Any monthly fee you’re quoted goes to whoever manages the account, not to Google.

So the question is whether the management pays for itself. At a small spend it often doesn’t. Spend €500 a month with Google and pay €450 plus VAT to have it managed, and the fee is about half of everything leaving your account. The campaign has to cover that before it earns you a cent.

Plenty of owners run their own account, and at that size it can be the right call.

The risk is paying for the wrong searches. Left on broad settings, a plumber’s ad can show for “plumbing apprenticeship” and “how to fix a dripping tap”, and you pay for every one of those clicks as if it came from a customer. Our piece on negative keywords shows how to shut them out.

Paying someone makes sense in two cases.

• Your time is worth more than the hours the account needs.
• The spend is big enough for trimming the waste to cover the fee. On €4,000 a month, if one click in eight is wasted, cutting it saves €500, which covers the €450 fee before VAT.

On Google’s side, stopping is simple: you can change or cut your budget from the account whenever you like. If someone manages it for you, check their notice period before you sign.

Should you sort your Google Business Profile before paying for ads?

For a local business, yes. Your Business Profile is free and it’s what shows in the map results. Someone who clicks your ad and then checks your reviews should find recent ones worth reading, and our advice on getting more Google reviews will help there.

You don’t have to pick one, though. The Profile competes for the searches where Google shows a map, and Google Maps ads are a separate route, covered in their own post. Ads in the main results can put you at the top of the page, while local SEO builds underneath.

How long do Google Ads take to work?

Clicks start the day your ads are approved. Knowing whether they’re worth it takes longer, and it depends on enquiries rather than the calendar.

Go back to Google’s learning figure of up to around 50 conversions. At one visitor in ten, a plumber on €10 a day gets about seventeen enquiries a month, so it could take around three months. Solar, at three a month, could take well over a year. Judge a campaign on its first week and you’re judging it half-built.

If the numbers still don’t work once the account has had that long, the money is better spent elsewhere.

Questions people ask about whether Google Ads are worth it

Are Google Ads still worth it in 2026?

For businesses people search for, yes. Search is still where people go when they need something now, and the paid results usually sit at the top of the page. What’s changed is how much Google automates, which makes clean conversion tracking matter more than it used to. The automation learns from whatever you tell it counts as a result.

Do people actually click on Google Ads?

Some people skip them. How often an ad gets clicked depends on how closely it matches the search and on your industry.

How do I claim a Google Ads promotional credit?

Google runs promotional credits for new advertisers, and Google’s terms come with conditions.

The code has to be entered within 14 days of your first ad showing, and you may have to spend a set amount and be billed for it first. The credit typically lands within 35 days of meeting the conditions, expires 60 days after it’s applied, and it’s one per customer.

The amount and the spend required are in the offer itself, so read Google’s promotional credit terms (checked October 2026) before counting on one.

Is Google Ads better than SEO?

They do different jobs. Ads can put you at the top of the page from the day they go live, and they stop the day you stop paying. SEO takes months to build and keeps paying after the work is done. A sensible split is ads for the searches that pay now and SEO for the ones that will keep paying.
