What Does a Google Ads Manager Actually Do (And What Should You Pay One)?

A Google Ads manager runs the strategy, build, and ongoing optimisation of your paid search campaigns so your budget produces leads or sales instead of clicks that go nowhere. The role covers campaign structure, bidding, keyword and negative-keyword management, conversion tracking, and regular reporting. The gap between a good manager and a poor one is enormous, and it rarely shows up in the price. It shows up three months later in your cost per lead.

This post is the companion to our pricing guide, Google Ads and AdWords pricing in New Zealand for 2026. That piece answers “what will this cost”. This one answers a different question that comes just before it: what does the person or agency you are paying actually do all day, and how do you tell whether they are any good? If you are weighing up who to hire rather than what to spend, start here and read the pricing guide second.

What does a Google Ads manager actually do day to day?

A Google Ads manager designs, builds, and continuously optimises your campaigns against a commercial goal, then reports on what that spend produced. The work is not a one-off setup. It is an ongoing cycle of watching the data, cutting what wastes money, and pushing budget toward what converts.

On a typical account, the recurring work breaks down into a handful of areas that we will walk through one at a time: account structure, bid strategy, keyword and search-term management, negative keywords, conversion tracking, reporting, and ongoing optimisation. Most of these are invisible to the business owner, which is exactly why “set and forget” managers get away with charging for months of doing very little. Once you know what should be happening, the difference becomes obvious.

What is campaign structure and why does it matter?

Campaign structure is how the account is organised into campaigns, ad groups, keywords, and ads, and it is the single biggest factor in whether an account is manageable or a mess. Good structure lets a manager control budget, match ads tightly to search intent, and read the data cleanly. Poor structure hides waste and makes every later decision harder.

A well-built account usually separates campaigns by the things you would want to control or budget for differently. That might be by service line, by location, by intent (someone searching “emergency plumber” is worth more than someone searching “how to fix a tap”), or by campaign type such as Search versus Performance Max. Inside each campaign, ad groups hold tightly themed keywords so the ad copy can speak directly to what the person typed.

The tell-tale sign of a rushed build is one campaign with a single ad group containing forty loosely related keywords and two generic ads. When everything is lumped together, you cannot see which service is profitable, you cannot shift budget toward what works, and your ads are too broad to be relevant to any single search. A manager who takes structure seriously is doing the unglamorous work that makes everything downstream possible.

How do bidding strategies work in Google Ads?

A bid strategy is the method used to decide how much to pay for each auction, and choosing the right one for the account’s stage and data is a core part of the job. Google offers manual and automated options, and the automated ones (“Maximise conversions”, “Target CPA”, “Target ROAS”, “Maximise conversion value”) lean on machine learning to adjust bids in real time based on signals a human cannot process fast enough.

The catch is that automated bidding is only as good as the conversion data feeding it. Point a smart bidding strategy at weak or broken tracking and it will optimise enthusiastically toward the wrong thing. A competent manager knows when an account has enough clean conversion history to hand control to automation, and when it is still too early and needs manual bidding or a simpler strategy while data accumulates.

This is where experience earns its keep. The decision is not “automated is better than manual”. It is matching the strategy to the account’s maturity, budget, and goal, then watching how the algorithm behaves and stepping in when it drifts. A manager who set “Maximise conversions” on day one with no conversion data and walked away is not running a bid strategy. They are hoping.

What are negative keywords and why do they save money?

Negative keywords are search terms you tell Google to ignore, and disciplined negative-keyword management is one of the clearest signs of an active manager versus an absent one. Without them, broad and phrase-match keywords pull in searches you never wanted to pay for.

Say you are a commercial electrician. Your keywords can trigger ads for “electrician jobs”, “electrician course”, “electrician salary NZ”, “free electrical advice”, and “DIY wiring”. Every one of those clicks costs you money and none of them is a customer. Negative keywords block them. The only way to find them is to read the search terms report regularly and add the junk as it appears, week after week, because new irrelevant searches surface constantly.

This is genuinely one of the fastest ways to spot a set-and-forget account. Open the search terms report and look at the last thirty days. If the negative keyword list has not grown and the report is full of obviously irrelevant terms still pulling clicks, nobody is minding the account. A manager doing their job treats the search terms report as a weekly habit, not an annual event.

Why is conversion tracking the part that gets skipped?

Conversion tracking is the setup that records when a click turns into something valuable, such as a form submission, a phone call, or a purchase, and it is the foundation everything else depends on. Without it, you are flying blind, and worse, so is Google’s bidding algorithm. Yet it is the piece most often set up badly or skipped entirely.

Proper tracking means the important actions are actually being recorded, phone calls are captured (not just form fills), duplicate or junk conversions are filtered out, and where possible the values passed back reflect real business outcomes rather than a raw count of clicks on a button. When this is right, you can finally answer the only question that matters: what did we spend, and what did we get for it?

A good manager treats tracking as the first job, not an afterthought, and audits it periodically because tracking breaks quietly. A site redesign, a new form plugin, or a changed thank-you page can silently kill your conversion data, and if nobody checks, you can burn budget for weeks optimising toward numbers that stopped being real. When a business tells us their previous campaigns “just stopped working”, broken tracking is one of the first things we check.

How often should a Google Ads manager report to you?

A reasonable reporting cadence is monthly at minimum, with the manager available for questions in between, and the report should be readable by a business owner rather than a wall of platform screenshots. Reporting is not just accountability. It is where the manager translates account activity into commercial language: what the spend produced, what changed, and what is planned next.

A useful report leads with the outcomes that matter to your business, cost per lead or cost per sale, number of enquiries, and return on ad spend where you sell online, then explains what was optimised and why. It should be honest about what is not working, because no account performs perfectly every month, and a manager who only ever reports good news is either hiding something or not looking hard enough.

Be wary of reports that drown you in metrics like impressions and click-through rate while never connecting spend to actual business results. Impressions do not pay wages. The right cadence also depends on spend: a large account moving quickly warrants closer contact than a modest one, but even a small account deserves a clear monthly picture of where the money went.

What does “ongoing optimisation” actually include?

Ongoing optimisation is the continuous cycle of testing, cutting, and reallocating that keeps an account improving rather than slowly decaying, and it is the work you are really paying a manager for month to month. A campaign is never finished. Competitors change their bids, search behaviour shifts, seasons turn, and Google updates its systems constantly.

In practice, month-to-month optimisation includes reviewing and refining the search terms report, adding negatives, pausing keywords and ads that spend without converting, testing new ad copy against the current best performers, adjusting bids and budgets toward what works, refining audience and location targeting, and reviewing landing pages that receive traffic but do not convert. None of these is dramatic on its own. Together, over months, they compound into a meaningfully lower cost per lead.

This is precisely what “set and forget” managers do not do. They build the account, switch on automated bidding, and let it run untouched while the monthly fee keeps arriving. The account might tick along for a while, then quietly degrade as the market moves and nobody adjusts. If you cannot point to specific changes made in your account over the past month, you are paying a management fee for something that is not being managed.

What separates a genuinely good Google Ads manager from a set-and-forget one?

The difference is engagement with the account and honesty about results. A good manager can show you what they changed recently and why, ties every decision back to a commercial goal, and tells you plainly when something is not working. A set-and-forget manager sends a login, switches on automation, and reappears only to invoice.

Here are the questions that separate the two, and they are worth asking before you sign anything:

What will you change in the first month, and how will you decide what to change after that? A good answer references the search terms report, conversion data, and testing. A vague answer about “monitoring performance” is a warning.
How is my conversion tracking set up, and how will you verify it is working? If tracking is an afterthought in the conversation, it will be an afterthought in the account.
Who owns the account? You should own your Google Ads account and keep access to it if you ever leave. If an agency locks you out of your own data and history, walk away.
How will you report, and what metrics will you lead with? You want cost per lead or sale and enquiry volume up front, not a vanity dashboard of impressions.
What happens when a month underperforms? Honesty here tells you whether you are dealing with a manager or a salesperson.

A good manager also knows when Google Ads is not the answer. If your margins cannot support the cost per click in your market, or there is simply no search demand for what you sell, the honest move is to say so rather than take your money. That candour is one of the strongest signals you can get.

What should you pay a Google Ads manager in New Zealand?

Management fees in the New Zealand market are generally structured as a flat monthly retainer, a percentage of ad spend, or a hybrid of the two, and what you pay should track the work and skill involved rather than a headline number. We cover the full breakdown in the Google Ads pricing guide, so here we will keep it to how the fee relates to the role.

A flat retainer suits accounts where the workload is fairly steady month to month and is the most predictable for a business owner to budget. A percentage of spend (commonly somewhere in the mid-teens as a proportion of ad budget in the local market, though this varies widely) scales the fee with the size of the account, which can make sense for larger budgets but can misalign incentives on smaller ones, since it rewards spending more rather than spending well. Hybrid models try to balance the two.

Whatever the structure, the fee should reflect that management is ongoing work, not a one-off setup. The cheapest option is rarely the cheapest outcome. A manager charging a low fee who then set-and-forgets your account can quietly waste far more in ad spend than a higher fee would have cost, because wasted clicks come out of your media budget, not theirs. Judge the fee against the total of management plus ad spend, and against the quality of the work described above, not against the retainer in isolation. For the actual ranges and how to compare quotes, read the pricing guide.

Should you hire a Google Ads manager or run it yourself?

Run it yourself if you have the time to learn the platform properly and your budget is small enough that mistakes are cheap; hire a manager once the spend is large enough that wasted budget outweighs the fee, or when you simply do not have hours each week to give it. Google Ads is learnable, but it rewards consistent attention, and most business owners run out of that attention long before they run out of things to optimise.

The honest test is opportunity cost. If you are spending a few hundred dollars a month and enjoy tinkering, running it yourself is a fine way to learn. Once you are spending enough that a poorly managed account wastes more than a manager would charge, or once the hours you spend on it are worth more elsewhere in your business, bringing in someone who does this every day usually pays for itself through lower waste and better conversion rates.

We have delivered more than 100 projects since 2018 and generated over $1M in revenue for clients from the leads and sales those campaigns produced, and the day-to-day discipline described in this post is exactly how we run every account.

Frequently asked questions

What does a Google Ads manager do?

A Google Ads manager designs, builds, and continuously optimises your paid search campaigns against a commercial goal, then reports on the results. The role covers account structure, bid strategy, keyword and negative-keyword management, conversion tracking, and ongoing optimisation such as reviewing search terms, pausing what wastes money, and testing new ads. It is ongoing work, not a one-time setup.

How much does Google Ads management cost in New Zealand?

Management fees are typically a flat monthly retainer, a percentage of ad spend, or a hybrid of the two, and they sit separately from the ad budget you pay Google. The right fee reflects the ongoing work and skill involved rather than a headline number, and the cheapest option is rarely the cheapest outcome once wasted ad spend is counted. Our Google Ads pricing guide breaks down the ranges and how to compare quotes.

How do I know if my Google Ads manager is any good?

Ask what they changed in your account in the last month and why. A good manager can point to specific optimisations, ties every decision to a commercial goal such as cost per lead, reports honestly when a month underperforms, and makes sure you own your own account and data. If nobody can show you recent changes and the search terms report is full of irrelevant clicks still being paid for, the account is not being managed.

What is the difference between a good manager and “set and forget”?

A good manager engages with the account continuously, reviews the search terms report, adds negative keywords, tests ads, and reallocates budget toward what converts. A set-and-forget manager builds the account, switches on automated bidding, and leaves it untouched while the monthly fee keeps arriving. The account may hold up for a while, then quietly degrade as the market shifts and nobody adjusts.

Can I manage Google Ads myself instead of hiring someone?

Yes, especially if your budget is small and you have time to learn the platform and check the account regularly. Google Ads is learnable but rewards consistent attention. The point where hiring a manager makes sense is when your spend is large enough that wasted budget outweighs the management fee, or when the hours the account demands are worth more elsewhere in your business.

Should I own my Google Ads account or does the agency own it?

You should own your Google Ads account and retain access to it if you ever change providers. Your account holds all the historical performance data and learning that makes future optimisation possible, so losing it means starting from scratch. Any manager or agency that locks you out of your own account is a serious warning sign.
