Learn Google Ads Yourself or Hire an Agency? An Honest Guide for Australian Small Businesses

DIY, freelancer or agency, compared fairly · Updated November 2026

Few marketing decisions cause as much second-guessing as this one. Google Ads spends real money every day, so getting it wrong hurts fast. Agencies say it is too technical to DIY. Plenty of online courses say agencies are a waste of money. The straight answer sits in the middle, and it depends on your budget, your time and how much risk you can carry while you learn.

This guide compares the three realistic options for an Australian small business: doing it yourself, hiring a freelancer, or hiring an agency. If you are still deciding whether Google Ads is the right channel at all, start with Google Ads vs Facebook Ads and whether Google Ads is worth it for small business, then come back here.

The Three Options at a Glance

How Google Ads Management Is Usually Priced

Prices vary so much by scope, location and provider that any single number would mislead you, so get written quotes. What you can do is understand the fee models, because each one creates a different incentive:

• Flat monthly management fee. A set amount each month regardless of spend. Easy to budget. Check exactly what is included: how often the account is reviewed, whether new ads and landing page advice are covered, and how reporting works.
• Percentage of ad spend. The fee rises as your budget rises. Common and simple, but notice the incentive: a manager paid on spend earns more when you spend more, not necessarily when you earn more. Often paired with a minimum monthly fee.
• Setup fee. A one-off charge to research keywords, build campaigns and set up conversion tracking. Reasonable for a proper build. Ask what you get to keep if you leave.
• Hourly or project rates. More common with freelancers. Good for a one-off build or a health check, less predictable for ongoing work.

Remember that every fee sits on top of your actual ad spend. For realistic click costs and budgets, see how much Google Ads cost in Australia. A useful gut check: if the management fee is close to, or larger than, the amount going to Google, most of your budget is paying for management rather than reaching customers.

Doing It Yourself: The Honest Pros and Cons

The case for DIY is simple. Nobody knows your customers, margins and busy seasons like you do, and nobody cares as much about every dollar. You keep full control, you see every search term that triggered your ads, and the skill stays in the business.

The costs are real too. You need time to learn, then a regular weekly slot to check search terms, add negative keywords and review results. Your first campaigns will include some wasted spend while you learn, which is the tuition fee nobody advertises. And Google keeps adding automation, such as Performance Max, that is easy to switch on and harder to understand. Our Performance Max vs Search guide explains why that matters.

DIY suits you if: your budget is modest, you sell a clear service in a defined area, and you can protect a regular block of time each week. Our step-by-step guide to setting up your first Google Ads campaign is a good place to start.

Hiring a Freelancer

A good freelancer gives you specialist hands without agency overheads. You usually deal directly with the person doing the work, which makes for faster changes and clearer conversations. Freelancers are often a strong fit for a one-off account build or audit, or ongoing management of a straightforward account.

The trade-offs: one person can only handle so much, holidays and illness mean gaps, and skill levels vary widely. Ask to see how they report, who covers when they are away, and make sure the account stays in your name.

Hiring an Agency

An agency brings a team, processes and experience across many accounts. That breadth is valuable when your account is big or complicated. The downsides are cost, the risk that a junior staff member runs your account day to day, and contracts with minimum terms that make it hard to leave if results disappoint.

When an agency is the better choice

We teach people to run their own marketing, and we will still say this plainly: sometimes an agency is the right call. Choose one when:

• Your monthly ad spend is large enough that small percentage improvements are worth a lot of money.
• You run e-commerce with a big product catalogue, Shopping feeds or several campaign types at once.
• You advertise across many locations, or in a very competitive, high-cost industry where mistakes are expensive.
• Your hourly value is clearly higher than the management fee, and you would rather spend that time on customers.
• You need tracking, analytics and landing page work handled together by people who do it every day.

The Hybrid Option: Learn the Basics, Then Decide

For most small businesses the smartest move is not choosing a side. It is learning enough to either run a simple account yourself or brief and manage a provider well. Owners who understand the basics write better briefs, spot wasted spend early and are far harder to fob off with vanity metrics. We make the same case for marketing in general in course vs hiring a marketing agency; Google Ads is where it matters most because the spend is immediate.

In practice, "the basics" means you can:

• Read the search terms report and tell relevant searches from wasted ones.
• Explain what counts as a conversion in your account, and check that tracking actually records calls, forms or sales.
• Understand match types, negative keywords and how your daily budget is spent.
• Run a quick monthly health check, like our 20-minute Google Ads audit, and diagnose problems with the not-converting checklist.

That is a few evenings of learning, not a career change. If you want a structured path, you can learn Google Ads in 20-minute lessons covering keyword research, budgeting, search ad analytics, retargeting and Performance Max, finishing with a draft Search campaign of your own.

Questions to ask any freelancer or agency before you sign

• Will the Google Ads account be in my business's name, and will I have my own login?
• If we part ways, do I keep the account, campaigns and history?
• What is the management fee, how is it calculated, and is it shown separately from ad spend on invoices?
• What is the minimum contract term and notice period?
• What counts as a conversion, and how will you prove tracking works?
• Will you share the search terms report with me each month?
• Who will actually work on my account day to day?
