Google Ads for beginners: how not to burn the budget on your first campaign

Google Ads is the fastest way to get enquiries online: a campaign can produce its first clicks within hours. It is also the fastest way to lose money if the account is built wrong. The difference comes down to a handful of settings.

This guide takes a beginner through a first campaign in order and says which default settings to change immediately and what a small business should realistically expect.

When Google Ads is worth it

Google Ads suits you when there is existing search demand for your service: somebody is actively looking for what you sell. It is especially effective for urgent needs (a burst pipe, a towing service, acute toothache), because the searcher wants a solution now.

It suits less well when nobody knows to search for your product, because nobody knows it exists. In that case Meta advertising and content work better: there demand is created, in search it is captured.

Before the first campaign: three prerequisites

1. Get the landing page right. The ad leads to a page that has to match exactly what was advertised, load fast and make getting in touch easy. The front page is almost always a poor landing page.

2. Set up conversion tracking. Without it you do not know which search terms produce enquiries, and optimisation is guesswork. Track form submissions, phone clicks and any purchases. This is an absolute prerequisite, not an extra feature.

3. Work out what a customer may cost. If the average sale is €2,000 with a 30 per cent margin, you have €600 of room per sale. If one in five enquiries turns into a sale, an enquiry may cost around €120. That number guides every decision.

Building the campaign step by step

1. Choose Search as the campaign type

A beginner should start with a search campaign, not with Performance Max. In a search campaign you can see which search terms produce and steer money precisely. Performance Max is effective, but it is a black box worth using only once data has accumulated.

2. Turn off the Display network

By default Google suggests showing your ads outside the search network too. Switch this off: it spends budget on cheap, low-quality clicks that look good in the stats and produce nothing.

3. Set the location precisely

Choose the area you actually serve. Check the location setting’s detail as well: the default also shows ads to people who are interested in your area but not in it. Change the setting to “presence”, so you reach only people who are there.

4. Choose keywords and match types

Start with 10–20 keywords that describe exactly what you sell. Use phrase match and exact match rather than broad match: broad match shows ads for loosely related searches too and burns a beginner’s budget fast.

5. Add negative keywords immediately

Block the words you do not want to appear for: “free”, “cheap”, “reviews”, “jobs”, “DIY”. That list is the single biggest cost saving there is, and it is worth topping up every week from the search terms report.

6. Write ads with a benefit and a call to action

Put the search term the ad answers into the headlines, along with a concrete benefit and a differentiator. “Roof repairs in Manchester”, “Fixed price and a 10-year guarantee”, “Request a free assessment visit”. Avoid generic promises every competitor uses.

7. Set a budget that generates data

Too small a budget does not produce enough clicks for you to optimise. A realistic start in most industries is a few hundred euros a month, but the right level depends on the click price: if a click costs €3 and you need 30 clicks per enquiry, calculate from there.

The first weeks: what to do

Week 1. Do not touch anything for the first few days; the algorithm is finding its bearings. Look at the search terms report and add negative keywords.

Week 2. Cut the keywords spending money without conversions. Add budget to the ones that produce.

Weeks 3–4. Test new ad copy. Compare the landing page’s conversion rate: if clicks arrive but enquiries do not, the problem is on the page, not in the ad.

After a month. Now you have data. You can consider an automated bidding strategy (maximise conversions, for instance) if enough conversions have accumulated.

Five expensive beginner mistakes

• Broad match without negative keywords. The fastest way to burn the budget on entirely irrelevant searches.
• Sending ads to the front page. The visitor has to hunt for what was advertised, and they leave.
• No conversion tracking. Optimising without data is guesswork, and Google’s automation does not work without conversion data.
• Too many keywords on too small a budget. A hundred keywords and €200 a month means no keyword gets enough data.
• Switching the campaign off after two weeks. Google Ads needs data to learn. Give it at least a month before drawing conclusions.

A campaign structure that stays under control

The most common reason an account gets out of hand is a muddled structure. The clear model is this: one campaign per service area or service group, and ad groups by theme inside it.

For a plumbing company, for instance: a “Pipe renovations” campaign with the ad groups “pipe renovation”, “drain relining” and “water pipe replacement”. Each ad group has a few closely related keywords and ads that match them.

This way you see immediately which service produces, you can move budget between services, and every ad answers exactly what was searched for. A muddled account with one ad group and a hundred keywords tells you nothing and cannot be optimised.

Quality scores and why they are worth knowing

Google gives keywords a quality score on a scale of 1–10. It is based on three things: how often your ad is clicked, how well the ad matches the search and how good the landing page is.

Quality scores affect money directly: with good scores you pay less for the same position than a competitor with poor scores. In practice this means the keyword, the ad and the landing page have to talk about the same thing. It is a simple principle that most people never act on.

Calls and extensions

For service businesses a call is often worth more than a form. Turn on the call extension so people can call straight from the ad, and set calls as conversions. You can also limit ads to appear only during opening hours if calls are the main way people get in touch.

The other extensions are worth filling in completely: sitelinks, callouts and location. They increase the size of your ad in the search result at no extra cost and clearly raise the click-through rate.

When to get help

You can learn Google Ads yourself, and on a small budget that is the right call. Professional help usually pays for itself when the monthly budget exceeds around a thousand euros, when competition is tough and clicks are expensive, or when the account has been running for months without results. In those situations the value of optimisation exceeds its price.

Frequently asked questions

How much does Google Ads cost?

You pay per click, and the click price varies by industry from a few tens of cents to several tens of euros. A realistic starting budget for a small business is typically from a few hundred euros a month upwards, and the right level is calculated from the value of a customer.

How quickly does Google Ads produce results?

The first clicks arrive within hours and enquiries often in the first week. Optimising a campaign takes data, though, so a realistic evaluation period is at least a month.

Is Google Ads worth it for a small business?

It is, if there is search demand for your service and the value of one customer covers the acquisition cost. For urgent services the return is often excellent. If the margin is very thin, other channels are worth considering.

What is a good conversion rate in Google Ads?

In service industries 2–8 per cent is the usual range, but the figure varies a lot by industry and by keyword. A more important metric is the cost per enquiry relative to the value of a customer.

Should you start with a Performance Max campaign?

Not as a beginner. Start with a search campaign, where you see keyword-level data and learn what works. Performance Max works best once the account already has conversion history the automation can learn from.
