When someone nearby searches for a plumber, a hairdresser or a garage, the first results are often adverts. Google Ads is how a business gets into that spot, and for a local business it can bring in enquiries quickly. It can also waste money fast if it is set up carelessly.

This guide to Google Ads for local businesses covers the three things that matter most at the start: knowing what counts as a win, choosing your area and stopping wasted searches.

What is Google Ads?

Google Ads lets you show adverts when people search for something you offer. Search ads reach people at the exact moment they are looking, which is why they suit urgent needs such as emergency repairs. The catch is that the traffic stops when you stop paying. SEO is slower to build but keeps working without a per-visitor fee, and many businesses use both. Our guide to SEO or ads first? helps you decide, and Google Ads vs Facebook Ads compares the two platforms.

1. Decide what counts as a win

Before you spend anything, decide what you want an ad click to lead to. Google calls this a conversion: a valuable action such as a purchase, a sign-up or a phone call. Google’s conversion tracking is a free tool in your account that measures how clicks on your ads lead to those actions. For most local businesses the wins are phone calls, enquiry forms and bookings.

How it works: you add a small piece of code to your website, and when someone clicks your ad, a temporary cookie is placed on their device. When they complete the action you defined, Google records a conversion. In the UK, tracking tools only run after a visitor accepts cookies, so tracking will never capture everyone. An honest ad manager will tell you that.

2. Choose your area

Your ads can be shown to people in a country, an area within it or a radius around a location. Google’s guide to targeting locations covers the options. A few things worth knowing:

• Radius targeting has a minimum. Google says a radius needs to be at least 1 km around a location.
• Very small areas may barely show. If the area is too small, your ads might show only now and then, or not at all.
• The default is “presence or interest”. This reaches people in or regularly in your area, and also people who have shown interest in it. Google offers “presence” alone if you only want people physically there.
• It is not exact. Google says location targeting is its best effort and 100% accuracy is not guaranteed.

Start where your customers really are, not just where your business sits. A plumber who covers three towns should target those towns, not the whole county. Our guide to how local SEO works explains the same idea for map results.

3. Stop wasted searches with negative keywords

A negative keyword tells Google not to show your ad for searches containing a word or phrase. Google’s example is adding “free”, so your ad does not appear for any search containing it. For a local business, useful negatives might be words that signal the wrong customer, such as “jobs”, “training” or “diy”, depending on what you do.

Two points from Google that catch people out:

• Match types matter. A broad negative blocks searches that contain all of its words in any order. Phrase and exact negatives are stricter about order.
• Close variants are not covered. Negative keywords do not automatically cover plurals or synonyms, so add the versions you want to block.

Check the searches your ads actually appeared for, and add negatives every few weeks. This is one of the cheapest ways to improve results.

4. Write ads that match the search

Say what you do, where you do it and how to get in touch. If someone searches for “emergency boiler repair” and your ad talks about “heating solutions”, you lose them. Use the words customers use, the same advice as on your website pages.

5. Send people somewhere useful

An ad that leads to a slow or confusing page wastes the click. Make sure the page matches the ad, loads quickly on a phone and makes it easy to call or enquire. Our guide to getting more enquiries from your website covers the fixes that matter most.

6. Check the results every month

Look at how many enquiries came in, what each one cost and what you changed. If someone else runs your ads, our five questions to ask your ad manager show what a good answer sounds like.

Common mistakes

• Targeting too wide an area, then paying for clicks from people you cannot serve
• Never adding negative keywords
• Judging by clicks instead of enquiries
• Stopping after a few days, before there is enough data to learn from
• Sending visitors to the homepage when a specific page would convert better
