Should You Manage Google Ads Yourself or Hire an Agency? A Straight Answer for Sydney

The genuine case for doing it yourself

Google Ads is not sorcery. The platform is public, the help documentation is better than its reputation, and an owner who is genuinely interested can build a small, tight Search campaign that brings in work. Nobody understands what a good customer looks like better than the person who quotes them. If most of the following describe you, keep your money and run it yourself.

Your ad budget is small. At roughly $800 a month of spend, a $750+GST management fee nearly doubles what the channel costs you. To justify that, an account has to be improved enormously, and on a budget that size there is often not enough data arriving each month for anyone, us included, to improve it quickly. Thin data is stubborn. It resists good management as much as bad.

You sell 1 clear thing. Complexity is what makes accounts expensive to run. A single service, a single price band and a single kind of buyer is a campaign you can hold in your head. It is a very different job to a business advertising 9 services across 3 categories, each with its own auction, its own margins and its own page.

Your service area is contained. An operator working the Inner West is running a far simpler geographic setup than one covering Penrith through to the Northern Beaches, where the same keyword has to earn its place in wildly different markets.

You have the hours and you do not resent them. This is the one that decides it. Somebody who finds the auction interesting will keep an account healthy for years. Somebody who finds it a chore will build it well in January and not open it again until the invoice looks alarming in June.

What running it yourself actually takes

The setup is the visible half: choosing the keywords worth bidding on, writing ads that match them, pointing the click at a page built for that search rather than a homepage, and wiring up conversion tracking so calls, form submissions and phone-link taps are all counted once and counted properly. Budget 12 to 20 hours for that first stretch if tracking and the landing page are part of it. Tracking is the step most owners skip because it is fiddly and invisible, and it is the one that decides whether every decision you make afterwards is informed or guessed.

Then comes the unglamorous part that never ends. Reading the search terms report and adding negatives. Checking which ad variations are pulling. Watching what a click costs this month against last. Noticing that a campaign quietly started serving in a suburb you do not service. Done honestly this is 3 to 6 hours a month, forever, and it is where nearly all of the result lives. An account is not built once. It is built and then defended.

Put a value on those hours. If your time is billable, 4 hours a month of your own attention is rarely the cheapest labour in your business. That is not an argument for hiring us. It is an argument for being honest with yourself about whether those hours will actually happen.

The 4 failures we find in almost every unsupervised account

When we open an account that has been running on its own for a year, the same 4 things are usually waiting. None of them are exotic. All of them are expensive.

1. Broad match left switched on. Broad match is the default and it is the single most effective way to spend a small budget on searches that were never going to become an enquiry. It is not useless, but it needs a mature negative list and conversion data to steer it, which is exactly what a new self-run account does not have yet.

2. An empty negative keyword list. If nobody has added negatives, the account is paying for people researching how to do the job themselves, people chasing jobs, people after free advice, and competitors having a look. Negatives are the cheapest performance work in Google Ads and the most consistently neglected.

3. Smart campaigns, or letting the automation run unattended. Google is very good at spending a budget in full. Smart campaigns hand over the keyword choices, the placements and much of the visibility, then report back in the flattering language of impressions and clicks. Automation genuinely works when it has clean conversion signals and a tight structure to work inside. Given neither, it optimises towards volume, because that is all you have given it to aim at.

4. No conversion tracking, or tracking that counts the wrong thing. This is the fatal one. Accounts count page views as conversions, or count a thank-you page load 3 times, or never fire at all. Without a reliable count of tracked enquiries, a call, a form or a phone-link tap, there is no way to know which keywords deserve the budget. Everything after that is decoration.

In-house, freelancer, agency: the other 3 doors

Hiring in-house only stacks up when there is enough work to fill the role. A salaried marketer costs many multiples of a management retainer once superannuation, software, training time and the recruitment gaps are counted, and paid search alone rarely occupies a full week. It starts making sense when ad spend is large enough that a percentage point of improvement pays the salary by itself, or when Google Ads is one slice of a genuinely full marketing job. The other catch is depth. One in-house person sees 1 account, so the pattern recognition that comes from watching many accounts in many auctions is not available to them.

A freelancer is often the cheapest supervised option and a good one can be excellent. The label matters far less than the answers to 3 questions: who touches the account, how the fee is worked out, and whose name the ad account is registered in. The real freelancer risk is availability. Holidays, illness and a better-paying client all mean weeks where nobody looks, and there is nobody behind them when that happens.

An agency buys you continuity and pattern recognition, and the good ones earn their fee by removing waste rather than by adding activity. The failure mode is well known: a percentage-of-spend fee, which pays the agency more every time more of your money leaves the account, a junior learning on your budget, and reports built around impressions because impressions always look like progress. Those are avoidable faults, not inevitable ones, which is why the questions above matter more than the category.

Where the crossover point sits

The crossover is not a budget threshold somebody can hand you. It is a piece of arithmetic you can run in a couple of minutes, and it goes like this: a management fee is worth paying when it is smaller than the waste it removes, plus the value of the hours it hands back to you. Open your search terms report and total the spend against terms you would never have quoted on. If that figure is comfortably above the fee, the maths already works. If it is close to nothing, your account is in better shape than most and you should keep running it.

A second, blunter test: how many weeks has it been since you looked? Neglect costs more than inexperience. We would back an engaged owner with 6 months of self-taught Google Ads over a dormant account that was professionally built and then abandoned, every time.

What management is actually buying is usually structure and attention rather than secret knowledge. On an interstate account for reference, a South Australian roofing client we manage runs at roughly $230 a day with each advertised service pointed at its own landing page: roof replacement converts at 31.13% for $75.79 per enquiry, gutter replacement at 30.00% for $55.31, tracked from October 2025 to July 2026. Read conversion strictly there, a call, a form submission or a phone-link tap, never a booked job or revenue. The gains came from separation and tracking, not from a lever you cannot reach yourself.

If you do decide to hire, 4 things to check first

Ask who personally touches the account, and get a name. Ask how the fee is calculated, and treat a percentage of ad spend as the warning it is. Ask whose business the Google Ads account will be registered to, because keyword history and conversion data are worth keeping and you should be able to walk away with them. Ask what gets counted as a result, and see whether the answer is enquiries or impressions.

For the record, ours are: Chris Lourenco, personally, as a Google Partner with 8 years, 200+ campaigns and $3M+ in managed ad spend behind him. A flat $750+GST a month, never a percentage, with no lock-in and $0 setup. The ad account is registered to your business from day 1. A result is a tracked enquiry. You can read how the Google Ads management works or see exactly what the flat fee covers.

If you are still not sure

Send the account for a free review before you decide anything. We will look through what you have built and the auction you are bidding into, and tell you which of the 4 failures above is present and what it is costing. If the honest answer is that you are running it well enough and should carry on, you will get that answer, and it will not cost you anything. Plenty of Sydney owners get exactly that reply.
