Google Ads is one of the most direct ways to reach customers, because it puts your business in front of people at the exact moment they’re searching for what you offer. It’s also one of the easiest ways to waste money, because the default settings are built for spending rather than for results. This guide walks through how Google Ads actually works, how to set up a campaign sensibly, and the mistakes that catch most small businesses out.

If you’re new to the whole idea of paying per click, what is PPC covers the basics first. And if you’re still deciding between Google and social ads, see Facebook Ads vs Google Ads.

How Google Ads Works

You choose the searches you want to appear for, write an ad, and set a budget. When someone searches for one of those terms, Google runs a quick auction and decides which ads to show. You pay only when someone clicks.

The auction isn’t won by budget alone. Google also considers how relevant your ad and landing page are to the search. A well-matched ad can appear above a competitor who’s willing to pay more per click.

The Main Campaign Types

• Search campaigns- text ads on Google search results; the best starting point for most local businesses
• Performance Max- Google’s automated campaigns across search, YouTube, maps and more; powerful but harder to control
• Display- image ads on other websites; better for awareness than for enquiries
• Local Services Ads- available for some trades, showing a ‘Google verified’ badge

Most small businesses should start with a tightly focused search campaign before trying anything else.

Setting Up Your First Campaign Properly

1. Choose specific searches

Target the searches your customers actually use, especially those with local and buying intent- like a service plus “Glasgow” or “near me”. Avoid broad single words that attract people who’ll never buy.

2. Add negative keywords

Negative keywords stop your ads showing for irrelevant searches- such as “jobs”, “free”, “DIY” or “course”. This single step prevents a large share of wasted spend.

3. Set your location carefully

Target only the area you actually serve, and set it to people located in that area rather than people merely interested in it. The default setting can show your ads to people nowhere near Glasgow.

4. Send clicks to a relevant page

Each ad should land on the page most relevant to what was searched- not just your homepage. A dedicated service page with a clear call to action will convert far more clicks. Our guide to website design for small businesses covers what that page needs.

5. Track conversions

Set up tracking for phone calls and enquiry forms before you spend anything. Without it, you’ll know how many people clicked but not how many became customers.

The Mistakes That Waste Budget

• Using broad keywords without negatives
• Leaving the default location settings in place
• Sending every ad to the homepage
• Running ads with no conversion tracking
• Letting Google’s automated suggestions change the campaign unchecked
• Setting it up and never looking at the search terms report

Many of these apply to social advertising too- our post on why Facebook and Instagram ads aren’t working covers the overlap.

Budget and Expectations

There’s no universal right budget, but there is a minimum below which a campaign can’t gather enough data to learn what works. It’s better to run one focused campaign with enough budget than to spread a small amount across many services. Expect the first few weeks to be about learning: which searches bring enquiries, which waste money, and which ads get clicked.

Google Ads and Your Business Profile Work Together

Paid search sits right above the map results driven by your Google Business Profile. Businesses that appear in both look more established and tend to get more clicks overall. If your profile isn’t set up properly, start with our Google Business Profile guide.

Frequently Asked Questions

Is Google Ads worth it for a small business?

It can be, particularly when people actively search for your service. The key is careful setup- specific keywords, negative keywords, tight location targeting and conversion tracking- so budget goes on people likely to become customers.

How much should I spend on Google Ads?

Enough to gather meaningful data for one focused campaign. Spreading a small budget thinly across many services usually produces poor results.

How long before Google Ads works?

Ads can bring clicks within days, but the first few weeks are about learning which searches produce enquiries. Expect to refine the campaign before judging it.

Should I manage Google Ads myself?

You can, if you have time to review search terms and adjust regularly. Many businesses start themselves and hand over once spend grows, as mistakes become more costly.
