Google Ads for small business: a beginner's guide

Google Ads for small business works like this: you choose the searches you want to appear for, write ads for them, set a daily budget and pay only when someone clicks. Done well, it puts your phone number in front of people at the exact moment they are looking for what you sell. Done carelessly, it sends your money to people searching for jobs, free advice or a competitor's name.

This beginner's guide walks through the parts of an account, the first decisions you need to make, and a sensible order for launching your first campaign. It is written for owners who want to understand what is happening in their account, whether they run it themselves or hire someone.

How an account is organized

Every Google Ads account has the same layers, and knowing them makes everything else easier to follow.

• Account: billing, users, conversion tracking and account-wide settings. It should be registered under your business email, not a freelancer's.
• Campaigns: each one has its own budget, location targeting, schedule and bidding strategy. Most small businesses need one to three.
• Ad groups: buckets of closely related keywords, for example "drain cleaning" separate from "water heater installation".
• Keywords: the phrases you bid on, with a match type that controls how loosely Google interprets them.
• Ads and assets: headlines, descriptions, your phone number, extra links, location and other add-ons that make the ad bigger and more useful.

A clean structure is not about tidiness for its own sake. When drain cleaning and water heater searches sit in the same ad group, you can't write a specific ad for either, and you can't see which one actually brings customers.

Which campaign type to start with

Google offers several campaign types, and the account creation flow will happily push you toward the most automated one. For a first campaign, the choice usually looks like this:

For most service businesses, Search is the right start. It catches people who already want what you offer, it is the easiest to read in reports, and it gives you real data on which searches turn into calls. I wrote a separate piece on Performance Max on a small budget if you are tempted by the automated route.

Six decisions to make before you launch

1. What counts as a conversion. A phone call longer than a minute? A form? A booked appointment? Decide this first, then set up tracking. Without it, Google optimizes for clicks, and clicks are not customers. My guide to conversion tracking for calls, forms and bookings covers the setup.

2. Where you want customers from. Use the area you actually serve. In the location options, choose to reach people who are in or regularly in your area, rather than people merely showing interest in it, unless you serve visitors and tourists.

3. Which services to advertise first. Start with the one or two with the best margin and the clearest search demand. You can add more later.

4. Keywords and match types. Phrase match and exact match keep you closer to the searches you want. Broad match can work later, once the account has conversion data and a solid list of negative keywords.

5. Budget and bidding. Begin with a budget you can hold for at least two to three months. Many accounts start on a click-based or simple conversion strategy, then move to target-based bidding once there are enough conversions to guide it.

6. Where the ad leads. A page about the advertised service, with your phone number visible on mobile, a short form and reasons to trust you. Sending everyone to the homepage is one of the most common beginner mistakes.

Settings that quietly waste money

When you create a Search campaign, a few defaults deserve a second look:

• The Display Network box is often ticked. It shows your text ads on websites and apps, where intent is much lower. Untick it for a first search campaign.
• Search partners extends ads beyond Google search. It is not bad, but keep an eye on it in reports.
• Auto-applied recommendations let Google change your account automatically, including adding keywords. Review them and switch off the ones you don't want.
• Ad schedule defaults to all hours. If nobody answers the phone at 2 a.m., calls at that time are lost money.

Writing your first ads

Responsive search ads let you enter up to 15 headlines and 4 descriptions, and Google tests combinations. Give it variety: the service and city, a concrete benefit, a reason to choose you, and a clear next step. "Same-day water heater repair" beats "Quality plumbing services" every time, because it says what you get.

Add assets: a call asset with your number, sitelinks to key service pages, callouts like "Licensed and insured" (only if true) and a location asset linked to your Google Business Profile. They make the ad larger and give people more reasons to click on you rather than the competitor below.

What the first 60 days look like

Week one is about checking that everything works: ads approved, tracking firing, calls coming through. From week two, the search terms report becomes your main tool. It shows what people actually typed before clicking, and you will almost certainly find irrelevant searches to block with negative keywords.

By the end of month two, you should know which keywords and hours bring inquiries and roughly what a lead costs. That is the moment to decide whether to scale up, narrow down or adjust the landing page.

Doing it yourself vs getting help

Many owners can run a simple search campaign with a few hours a week and a willingness to read reports. Others would rather spend those hours on their business. If you are weighing it up, my article on whether to manage Google Ads yourself or hire someone lays out the trade-offs honestly.

If you want a clean start, my Google Ads account setup costs $600 and includes structure, keywords, ads, conversion tracking and a walkthrough on Zoom, with the account registered in your name.
